Saturn has surprised us with geometry before. Its north pole hosts a famous hexagon that has endured through every observation for more than four decades. However, spacecraft and telescopes had never found a comparable polygon in the planet’s southern hemisphere. Now Saturn has answered that old mystery with a new one. Instead of six sides, the southern pattern has ten.

The discovery does not mean a rigid decagon floats above the planet. Nor does it mean that ten separate hurricanes have arranged themselves into a perfect ring. Rather, researchers see a giant wave moving through a powerful jet stream. That distinction makes the finding even more fascinating because the shape emerges from nothing more solid than gas in motion.

Saturn Decagon Explained: What Did Hubble Find?

On September 2, 2026, a research team reported the first large, regular-sided jet pattern ever observed in Saturn’s southern hemisphere. The peer-reviewed study, “A decagon wave around Saturn’s south pole,” appeared in Science Advances. A companion NASA Hubble announcement described the feature as giant, evolving and vertically extended through several atmospheric layers.

Hubble images place the wave near 63 degrees south latitude, where it loops around the polar region. In pictures taken at selected wavelengths, alternating changes in clouds and haze trace ten broad sides and vertices. Some corners look sharper than others. Consequently, the researchers think the structure may still be developing or may remain less stable than the northern hexagon.

The team found faint evidence of the pattern in Hubble observations from 2023. It became easier to recognize in 2024 and looked clearer again in 2025. Therefore, the data support the idea that the decagon has strengthened during the short period in which astronomers have tracked it.

Nevertheless, scientists cannot yet name its birthday. Saturn’s axial tilt hid much of the southern polar region from Earth for years, while no spacecraft has orbited the planet since Cassini ended its mission in 2017. The pattern may have emerged during that blind interval. In other words, astronomers know when it entered the available record, but they do not know precisely when it formed.

Is Saturn’s Ten-Sided “Storm” Really a Storm?

Calling the decagon a storm makes a dramatic headline, although “atmospheric wave” gives a more accurate description. The shape sits inside a high-speed jet stream rather than behaving like one self-contained cyclone. Gas races along that jet at a maximum speed of roughly 400 kilometers per hour, or about 250 miles per hour.

Meanwhile, the entire ten-sided pattern drifts much more slowly relative to Saturn’s rotation. The research team measured that motion at around 10 kilometers per hour, or 6 miles per hour. Its corners also oscillate with a period of about 32 days, a behavior that scientists have not observed in the northern hexagon.

Think of a river current that develops a repeating series of bends. Water continues to flow rapidly, even though the larger wavy pattern may shift at a different speed. Saturn’s atmosphere creates a far more complex version of that process. Because the planet lacks a solid surface, its gases can organize into enormous bands, vortices and waves without mountains or continents breaking the flow.

The polygon also reaches through more than one visible cloud level. Hubble photographed Saturn through different filters, and each wavelength sampled a different altitude. The decagon appeared in those separate views, although its position shifted slightly with height. As a result, the feature is not merely a thin color marking painted across the topmost clouds.

How Can Weather Form Straight Sides and Sharp Corners?

Weather rarely looks geometric on Earth, so Saturn’s polygons can seem almost artificial. However, fluid motion can produce regular shapes under the right conditions. Rapid rotation, strong differences in wind speed and the depth and stability of an atmosphere can force a jet stream into a repeating wave.

Saturn completes one rotation in roughly 10.7 hours. That fast spin strongly redirects north-south motion, helping to stretch atmospheric circulation into east-west bands. Moreover, the gas giant offers no solid ground to create the irregular friction that shapes weather on Earth. A meandering jet can therefore settle into a repeating pattern that resembles a polygon when viewed from above.

Scientists have reproduced polygon-like flows in rotating laboratory tanks. Depending on the rotation rate and the properties of the fluid, those experiments can create squares, hexagons, octagons and other shapes. Still, a laboratory demonstration does not reveal exactly what Saturn is doing beneath its clouds.

The new study used simplified numerical simulations to explore the southern feature. Those early models showed that a decagonal wave can arise in more than one way and survive for a time on its supporting jet. However, the researchers have not yet identified the actual trigger. A nearby atmospheric disturbance may have helped start the wave, but continued observations and more advanced models must test that possibility.

Saturn’s Southern Decagon Versus Its Northern Hexagon

The northern hexagon gives scientists an obvious comparison. Voyager 1 and Voyager 2 first recorded that six-sided jet during their Saturn flybys in 1980 and 1981. Later, Cassini studied it in remarkable detail. According to NASA’s overview of the hexagon, the northern structure spans about 30,000 kilometers, or 20,000 miles, and contains winds near 500 kilometers per hour.

Despite their shared geometry, the two patterns do not behave like twins.

Most importantly, scientists do not know whether both polygons come from the same underlying physics. A shared mechanism could produce different numbers of sides as wind speed, latitude, atmospheric depth or stability changes. Alternatively, the resemblance may hide important differences. The decagon’s motion and uneven corners already suggest a more dynamic structure.

Why Didn’t Cassini See the Decagon?

Cassini orbited Saturn from 2004 until 2017, and the spacecraft transformed our understanding of the planet. It repeatedly viewed the southern atmosphere. Yet those observations revealed no sign of a persistent south-polar polygon comparable to the northern hexagon.

That absence matters. If the decagon had remained stable for many decades, Cassini should probably have detected it. Therefore, researchers suspect that something changed after or late in the spacecraft’s mission. Seasonal shifts may have altered the southern jet, or a disturbance may have pushed an unstable current into a ten-lobed wave.

However, the missing years leave room for uncertainty. Saturn takes about 29 Earth years to orbit the Sun, so each season lasts more than seven years. The planet’s tilt gradually carried the south pole away from Earth’s view around 2012. It did not begin returning to a useful viewing angle until 2023.

Thus, the decagon could have formed while the pole remained hidden. It might also have existed as a weak wave that earlier instruments could not distinguish. The current evidence favors a recent and strengthening feature, but it does not prove that the atmosphere created all ten sides at a single identifiable moment.

Amateur Astronomers Helped Reveal a Planetary Giant

One of the best parts of this discovery happened far from a billion-dollar space telescope. The University of the Basque Country operates the Planetary Virtual Observatory and Laboratory, which collects images from observers around the world. In 2024, lead researcher Agustín Sánchez-Lavega and amateur astronomers Trevor Barry and Jean-Paul Oger noticed a faint, undulating band near Saturn’s south pole in those ground-based pictures.

Additional observations during 2025 strengthened the case. Moreover, a wider amateur network followed the changing vertices across the year. Those images helped the team measure the pattern’s slow movement with greater precision.

Hubble then supplied the sharp, consistent views needed to confirm the geometry. Because the telescope works above Earth’s atmosphere, terrestrial turbulence cannot blur its images. Hubble can also record Saturn throughout a complete rotation, letting researchers compare the wave from many angles.

This collaboration shows why patient skywatching still matters. Professional observatories cannot watch every planet every night. In contrast, skilled amateurs can gather frequent images, flag unusual changes and preserve a record that guides larger instruments toward the most promising targets.

Hubble and the VLT Looked Through Saturn’s Layers

The discovery relied on more than a single beautiful photograph. Hubble’s OPAL program—the Outer Planet Atmospheres Legacy program—has imaged the outer planets every year for more than a decade. Consequently, researchers could return to earlier data and watch the faint pattern become more obvious.

For example, Hubble observed the decagon in red and near-infrared light, including a wavelength near 763 nanometers and a methane-absorption filter near 889 nanometers. Those filters highlight different cloud and haze levels. Comparing them revealed vertical structure rather than a flat marking at one altitude.

Researchers also used the European Southern Observatory’s Very Large Telescope in Chile. Mid-infrared observations measured heat coming from Saturn’s troposphere and stratosphere. According to the University of Leicester research announcement, those temperature measurements helped the team estimate atmospheric stability and changes in wind speed with height.

Together, the observatories produced something closer to a three-dimensional weather report. Hubble traced clouds and haze, while the VLT measured thermal structure. Ground-based observers, meanwhile, supplied the frequent time coverage needed to follow the decagon’s motion.

Could the Decagon Last for Decades?

Nobody knows. The northern hexagon has survived for at least one full Saturnian year, which equals nearly three Earth decades. The southern wave, however, looks less settled. Several of its vertices remain weak, and its corners oscillate in a way the hexagon’s corners do not.

Even so, instability does not guarantee a quick disappearance. The jet may continue feeding the wave and sharpen it into a more regular structure. Conversely, changing seasons or another disturbance could weaken the pattern until it fades from view.

Astronomers now have a valuable baseline. Continued Hubble observations will reveal whether the sides strengthen, migrate or break apart. In addition, the James Webb Space Telescope can examine Saturn at infrared wavelengths that probe different pressures and temperatures. More sophisticated computer models can then test which atmospheric conditions reproduce the observations.

The timing makes this discovery unusually useful. Scientists normally find a planetary feature after it has already settled into place. This time, they may be catching one during its early development. If so, every new observation can test ideas about how giant atmospheric waves grow and stabilize.

Why This Strange Shape Matters Beyond Saturn

The decagon offers more than another entry in Saturn’s catalog of oddities. Giant planets act as natural laboratories for fluid dynamics under conditions that Earth cannot reproduce. Their rapid rotation, deep atmospheres, powerful jets and internal heat create weather on scales far beyond terrestrial storms.

Moreover, Saturn may help scientists compare different kinds of polar geometry. Jupiter has groups of cyclones arranged in five- and eight-sided patterns around its poles. However, those formations consist of multiple cyclones rather than one polygonal jet wave. Understanding the contrast could show which ingredients create a wavy boundary and which organize separate vortices into a ring.

The research also asks a deceptively simple question: Why does Saturn appear to be the only planet with these enormous polygonal waves? The answer may reveal how wind changes with depth, how polar jets exchange energy and whether disturbances from nearby storms can lock a fluid current into a stable shape.

Ultimately, planetary science grows through comparisons. Earth, Jupiter and Saturn all obey the same physical laws, yet each atmosphere expresses them differently. By studying the exceptions, scientists can discover which factors truly control the weather.

What Scientists Still Need to Learn

The researchers have strong evidence for the decagon’s existence, location and movement. Nevertheless, the largest questions remain open:

• What triggered the wave?
• How deeply does it extend below the visible clouds?
• Why did the southern jet produce ten sides instead of six?
• Does the decagon share a mechanism with the northern hexagon?
• Will the pattern strengthen, stabilize or disappear?
• Did Saturn’s long southern winter help create it?

Future observations should become easier as Saturn’s southern hemisphere turns farther toward Earth. Meanwhile, repeated measurements will show whether the pattern follows a seasonal cycle or responds to short-lived disturbances. Each year of data will make the models harder to fool.

That last point matters. A computer can create an attractive ten-sided wave under several sets of assumptions. However, only a model that matches the decagon’s altitude, jet speed, drift and 32-day oscillation can begin to explain the real atmosphere.

Frequently Asked Questions About Saturn’s Decagon

Does Saturn really have a ten-sided storm?

Saturn has a real ten-sided atmospheric pattern, but scientists describe it as a wave embedded in a jet stream. “Storm” works as a simple nickname, although the decagon is not one self-contained cyclone.

When did scientists discover Saturn’s decagon?

Researchers announced the discovery on September 2, 2026. Hubble data show that the feature was already faintly visible in 2023, and ground-based observers noticed signs of it in images from 2024. It became more pronounced in 2025.

Where is the decagon located?

The wave encircles Saturn’s south-polar region and centers near 63 degrees south latitude. It sits within a powerful east-west jet stream.

How is the decagon different from Saturn’s hexagon?

The decagon has ten sides, lies in the southern hemisphere and appears to be evolving. In contrast, the six-sided northern hexagon has remained recognizable for more than 40 years. The southern pattern also drifts and shows a roughly 32-day oscillation in its vertices.

Can amateur astronomers see it?

Highly skilled amateurs with suitable telescopes, imaging equipment and processing techniques contributed observations that helped reveal and track the wave. However, casual backyard viewing through an eyepiece will not show a crisp ten-sided outline.

What caused the decagon?

Scientists do not know yet. The leading possibilities involve instabilities or disturbances in Saturn’s southern jet stream. Simplified simulations can produce a ten-sided wave, but researchers need more observations to identify the conditions that created Saturn’s actual feature.

Will the decagon remain on Saturn permanently?

Researchers cannot yet predict its lifetime. It could stabilize and persist, or it could weaken as Saturn’s atmosphere and seasons change. Continued observations from Hubble, Webb and ground-based telescopes should reveal its fate.

Saturn Has Drawn a New Line in the Clouds

Saturn decagon explained does not end with a tidy solution. Instead, the discovery gives astronomers a mystery they can watch unfold. A fast jet of hydrogen-rich gas has organized itself into ten enormous sides, and nobody yet knows why it appeared now, why it chose that shape or how long it will survive.

That uncertainty is the exciting part. The northern hexagon showed that a planetary atmosphere can preserve astonishing geometry for decades. Now the southern decagon may reveal how such a pattern begins—or how it fails.

The possibility raises a delightful question. What if a building’s final day at one location marked the beginning of another chapter?

However, this story reaches much further back than a modern research laboratory. Roman monuments, an Anglo-Saxon crypt, and a famous Victorian exhibition hall all offer different versions of the same idea. A structure may lose its original purpose while its materials still have useful work to do.

How Reusable Brick Walls Work

Researchers at Graz University of Technology worked with brick manufacturer wienerberger on the Re-Use Ziegelwand project. Their approach centers on prefabricated wall elements with detachable connections. Instead of recovering individual bricks after demolition, the system aims to preserve entire wall sections for another building. Its intended applications include supermarkets and other buildings with comparatively short service lives. TU Graz project overview

Crucially, the connections between panels differ from the bonds within them. The research paper describes factory assembly using polyurethane adhesive between bricks. Reversible joints connect the finished elements on site. Typical panels measure approximately four meters long and three meters high. Therefore, think of reusable wall assemblies, rather than loose bricks that simply click apart. Popek and colleagues, 2026

The university reports 44-centimeter-thick walls with insulating wool inside the bricks and factory-applied plaster. Stability comes from sufficient roof weight or tensioned vertical threaded rods, depending on the design. The team also dismantled its demonstration building and reconstructed it at another location, where it remained functional. TU Graz research announcement

That last step matters. A drawing can show where components should separate. A reconstruction tests whether those components can come back together and do their job.

What the 60% Emissions Estimate Actually Means

In its May 21, 2026 announcement, TU Graz reported an estimated CO₂ reduction of around 60% over three life cycles compared with conventional construction. That is a projected benefit of repeated reuse, not a measured reduction from decades of operation. TU Graz research announcement

The related life-cycle paper examines a different scenario: five ten-year supermarket cycles. It distinguishes wall-level benefits from whole-building results and excludes operational energy from its listed assessment stages. Consequently, readers should not interpret the headline percentage as a guaranteed cut in every building’s total footprint. The authors also describe their calculation as an initial static assessment and identify uncertainty analysis as future work. Popek and colleagues, 2026

The underlying logic is straightforward. Reusing a serviceable component can avoid manufacturing its replacement. However, moving, inspecting, storing, and reinstalling that component still require resources.

Imagine buying a sturdy dining table, then taking it with you through three homes. Its value comes from continued service. Buying three tables and discarding two creates a very different material story.

A wall presents much harder engineering questions, of course. Nevertheless, the principle remains familiar: keep using something that still works.

Roman Stone Had Second Careers, Too

Long before anyone discussed carbon accounting, builders incorporated older architectural pieces into new work.

For example, Rome’s Arch of Constantine contains sculptural reliefs from the eras of Trajan, Hadrian, and Marcus Aurelius. Dedicated in AD 315, the arch combined earlier material with new work to celebrate Constantine. According to the Colosseum Archaeological Park, those borrowed images helped connect his authority to Rome’s imperial past. Here, reuse carried a political message as well as supplying material. Colosseum Archaeological Park

Centuries later, Roman stone found another life in northern England. English Heritage identifies material from structures at Chesters and Corbridge in the late seventh-century crypt and associated church at Hexham Abbey. Those sources included bridges and a large mausoleum. English Heritage’s masonry analysis

Moreover, the crypt still preserves clues to those earlier lives. Hexham Abbey describes carved decoration and inscribed stones, including a fragment of an altar dedicated to Maponus Apollo. The materials did not arrive as anonymous blocks. They brought traces of previous buildings and beliefs into their new setting. Hexham Abbey

These examples deserve a distinction from today’s environmental projects. Ancient and medieval reuse could involve appropriation and the loss of earlier monuments. It was not automatically a conservation effort.

Still, the surviving stones make one point difficult to miss: the lifespan of a building and the lifespan of its materials need not match.

The Victorian Palace That Moved

The Crystal Palace adds another chapter to this history.

After hosting London’s Great Exhibition of 1851 in Hyde Park, the building came down and rose again near Sydenham Hill. Its second version was larger and redesigned, rather than an exact reconstruction. Queen Victoria opened it on June 10, 1854. London Museum

The example broadens the story beyond salvaging individual stones. A major building could supply components for a new arrangement at another location.

Of course, one spectacular relocation does not establish an easy method for every building. Its relevance lies in the possibility it demonstrated: architecture can change address and form without starting entirely from scratch.

From Salvage to Buildings Designed for Disassembly

Modern deconstruction carries this thinking into everyday construction. Crews carefully recover useful components, rather than treating everything as demolition debris. The U.S. Environmental Protection Agency describes opportunities ranging from individual fixtures to entire assemblies and structures. It also notes that good bricks paired with weaker mortar can make recovery easier. EPA deconstruction guidance

However, recovering something after construction presents a different challenge from planning its recovery before construction begins.

Buildings designed for disassembly address that problem early. EPA recommendations include accessible connections, durable materials, modular components, mechanical fasteners, and a documented disassembly plan. EPA design guidance

Consider a simple design question: can a worker reach the connection without destroying the surrounding material? If the answer is no, the component’s theoretical reuse value may offer little practical help.

Similarly, the European BAMB project treats reversible design as useful during a building’s working life. Separating building layers can make repairs, replacements, and changes of use easier. Reuse need not wait until the entire structure becomes redundant. BAMB reversible design guidance

That suggests a wider ambition. A good building could accommodate change while protecting the components that do not need changing.

Buildings as Material Banks

The phrase buildings as material banks sounds like a metaphor. It also describes a practical research agenda.

The European Union’s BAMB project ran from 2015 to 2019, bringing together 15 partners. It combined reversible building design with digital materials passports: records describing characteristics that give materials and components value for use, recovery, and reuse. European Commission project report

In this model, a building temporarily holds useful resources. Its next owner or dismantling team needs reliable information about what those resources are.

For example, imagine a recovered wall panel arriving with a readable record of its dimensions, composition, previous inspections, and connection details. That hypothetical record would answer questions a photograph cannot. A buyer could begin assessing whether the panel suits a proposed building before arranging its transport.

However, a digital record cannot repair damage or create demand. Someone still needs the component, and its condition must support the intended use.

The appeal is the combination. Detachable connections make recovery possible; dependable information helps people decide what to recover and where it might go next.

What Still Needs to Happen?

A successful demonstration establishes an important starting point. Long service, repeated handling, and routine commercial use present further questions.

TU Graz describes vibration-based testing, known as modal analysis, to help assess wall condition over time. Changes in a wall’s natural vibration behavior can inform evaluation without destructive testing. TU Graz research announcement

For wider adoption, the practical questions include:

• Condition: What damage has a panel experienced, and what inspection does its next use require?
• Compatibility: Will its dimensions and connections suit the proposed building?
• Logistics: Where will crews store it between projects, and how far must it travel?
• Economics: Will recovery and reinstallation make sense for both seller and buyer?

These questions follow from the reuse model; they are not problems that one reconstruction could settle for every future project.

Furthermore, keeping an existing building useful may avoid the need to dismantle it at all. EPA includes preservation and adaptation among its approaches to reducing construction waste. EPA resource guidance

The most useful future wall may be one that can move when necessary—and remain in place when moving serves no purpose.

Frequently Asked Questions

Does this system eliminate every permanent bond?

No. Adhesive holds bricks together within the prefabricated elements. Reversible connections allow separation of the larger panels. The innovation centers on reusing those assemblies. Popek and colleagues, 2026

Has a building actually been dismantled and rebuilt?

Yes. TU Graz reports that its demonstration building remained functional after dismantling and reconstruction at another location. TU Graz research announcement

How is reuse different from recycling?

Reuse keeps an item or component in service. Recycling processes discarded material into another material or product. Moving an intact wall panel and crushing masonry for aggregate follow different paths. EPA materials guidance

Can an ordinary brick building work this way?

Not automatically. Recovering existing masonry depends on its materials, connections, and condition. The Graz concept designs detachable connections into a purpose-built system. EPA deconstruction guidance, TU Graz project overview

A Building’s Last Day Could Be Its Next Beginning

Reusable brick walls offer a fresh way to think about permanence. We can value a component’s durability while allowing its surroundings and purpose to change.

Roman stone acquired new meanings in later monuments and churches. The Crystal Palace found another address. Today’s researchers are asking how to make future reuse a deliberate part of construction.

Perhaps tomorrow’s demolition site will sometimes look more like a carefully organized departure lounge. The building has finished its job. Its walls have somewhere else to be.

The post Reusable Brick Walls: The Buildings That Get a Second Life appeared first on The Chronicle of Curiosity.

Published in Science Advances on August 26, 2026, the research challenges the idea that Egyptian painters followed a few simple, predictable formulas. Instead, their workshops drew from a surprisingly broad pantry of biological materials. Cattle supplied much of the glue, but sheep or goats, donkeys, horses and perhaps wild antelopes also contributed. Most remarkably, the team found the first taxonomically specific molecular evidence of sesame and moringa products in painted ancient Egyptian artworks.

The discovery does more than add two unusual items to an ancient supply list. It offers a glimpse of resourceful craftspeople who understood how natural materials behaved. Moreover, it shows how modern science can recover a lost recipe without finding a written recipe at all.

Egyptian Paint Was More Than Ground-Up Color

Every paint needs two basic parts. Pigment supplies the color, while a binder holds the pigment particles together and helps them cling to wood, plaster, stone or cloth. Without a suitable binder, even the richest red ochre or brightest Egyptian blue would behave like loose dust.

Ancient craftspeople could choose from many natural binders. Plant gums, waxes, eggs and protein-rich animal glues all offered different working properties. For example, a water-based glue could produce a relatively quick-drying paint. Beeswax, by contrast, supported the encaustic techniques associated with many later Romano-Egyptian mummy portraits. The binder influenced the paint’s flow, gloss, texture and durability as much as the pigment influenced its color.

However, organic binders create a problem for archaeologists. Minerals often leave recognizable chemical signatures, but proteins and oils decay, mix with burial material and suffer through old conservation treatments. Scientists may also need to remove a microscopic sample from a priceless object. Consequently, researchers know far more about many Egyptian pigments than they know about the invisible substances that held those pigments in place.

That gap makes the new research especially valuable. It shifts attention from the colors that viewers see to the biological machinery that made those colors usable.

Twenty-Eight Tiny Samples and 1,800 Years of Art

Clara Granzotto and an international team studied 28 microsamples from 14 artworks. Together, the objects span roughly 1425 BCE to 400 CE. The selection included painted wooden coffins, cartonnage, tomb-wall fragments, a mummy mask, plasterwork and limestone architectural elements.

The objects now belong to three collections: the Museum of Mediterranean and Near Eastern Antiquities in Stockholm, the British Museum in London and the Ny Carlsberg Glyptotek in Copenhagen. One example came from the famous tomb of Nebamun at Thebes. Another came from a painted coffin fragment in Stockholm, cataloged as MM 13944. Although the sample set remains small, it crosses many centuries, object types and workshop traditions.

Researchers removed minute flakes with surgical blades and needles. Next, they used mass spectrometry-based proteomics to break surviving proteins into smaller chains called peptides. Those peptide patterns work somewhat like fragments of a molecular barcode. By matching them against reference databases, the scientists could identify not only broad categories such as “animal glue,” but also likely species and tissues.

The team then combined proteomics with Fourier-transform infrared spectroscopy and pyrolysis-gas chromatography–mass spectrometry. Each technique answered a different part of the puzzle. Together, they revealed a recipe far more complicated than any single test could show.

The Animal Glue Cabinet Was Surprisingly Crowded

Cattle provided the most common source of collagen among samples that contained animal glue. Still, the results did not stop with cattle. The team also detected evidence linked to sheep or goats, donkeys, horses and possibly an antelope. Egg-white and egg-yolk proteins appeared in some material as well.

Animal glue usually comes from heating collagen-rich body parts in water. Many modern descriptions casually picture ancient glue makers boiling bones. However, the protein evidence in this study points strongly toward hides and other connective tissues in several cases. That distinction matters because it says something about raw-material selection and workshop practice. Egyptian artisans or their suppliers may have processed skins, tendons and related butchery byproducts into useful adhesive.

Meanwhile, the variety raises a question that the study cannot yet settle: Did artists request a particular animal, or did glue makers use whatever suitable material they could obtain? The samples revealed no simple one-animal formula that endured across the entire period. Availability, price, local custom and the demands of a specific object could all have influenced the choice.

Rather than imagining one official Egyptian recipe, we should picture a flexible technology. Skilled artisans likely judged glue by how it mixed, brushed, dried and held. Therefore, the material’s performance may have mattered more than its species name.

Sesame and Moringa Changed the Story

The plant proteins delivered the study’s biggest surprise. Scientists identified seed-storage proteins from sesame (Sesamum indicum) and moringa (Moringa oleifera). Seeds keep these proteins as food for a developing plant, so their presence points to seed-derived material rather than a stray leaf or a piece of wood.

In the Stockholm coffin fragment MM 13944, for instance, a red paint sample contained strong molecular signals from both plants. The team also detected moringa in material from more than one museum collection. Therefore, the result does not look like one unexplained speck from a single object.

Earlier chemical methods usually targeted a short list of familiar art materials. They could often distinguish glue, egg or milk, yet an unexpected plant protein might escape notice. Proteomics asks a wider question: Which protein sequences appear in this sample? That open search helped the ancient Egyptian paint ingredients emerge from molecular data instead of from assumptions about what artists “should” have used.

The result carries another historical implication. Scholars have long discussed when sesame and moringa reached Egypt and how Egyptians used them. According to the researchers, these proteins may provide the first molecularly based, taxonomic confirmation that products from both plants existed and served a purpose in ancient Egypt. Nevertheless, the study identifies the biological source more confidently than it identifies the exact workshop procedure.

Were the Artists Painting With Seed Oil?

Both sesame and moringa produce valuable oils. At first glance, then, an oil-based paint sounds like the obvious explanation. The chemical evidence points in a different direction.

Pure, well-filtered oil should contain abundant fatty compounds but relatively little seed-storage protein. In contrast, the samples held protein-rich material alongside only traces of oil. The researchers therefore propose that artisans may have used seed cake, the solid material left after workers crushed or pressed seeds for oil. Ancient processors could have ground that residue, mixed it with water or another liquid and added the resulting material to paint or adhesive.

This interpretation neatly explains why protein and oil appeared together. In addition, it turns an oil-making byproduct into a useful workshop resource. Modern defatted seed meals can still contain substantial protein, and protein-rich substances can influence how mixtures bind or spread.

Yet no one has recovered an Egyptian label that reads “add one scoop of moringa cake.” The study supports the seed-processing hypothesis through several analytical methods, but it does not prove the precise preparation, concentration or purpose. Perhaps the material acted as a binder. Alternatively, it may have modified texture, extended a more expensive ingredient or entered a mixture for another practical reason. Future experiments with reconstructed recipes could test those possibilities.

A Practical Ingredient, a Sacred Symbol—or Both?

The choice of moringa may carry cultural meaning. The study notes an ancient association between the moringa tree and Ptah, the Memphite god closely connected with craftspeople and creation. Egyptian artisans could have understood a moringa product as more than convenient workshop material, especially on funerary objects shaped by religious purpose.

Sesame and moringa oils also held value outside painting. People used plant oils in food, medicine, body care, ritual and mummification. Consequently, the ingredients belonged to wider networks of farming, trade and specialized processing. A painter who acquired seed residue may have stood at the end of a supply chain that began in a field and passed through an oil press.

Even so, symbolic meaning remains a possibility rather than a demonstrated fact. The surviving proteins cannot tell us what an artist believed. Nor can they reveal whether a workshop bought a prestigious sacred material or simply reused an affordable byproduct. Practical and religious motives did not have to exclude each other, either. Ancient Egyptians routinely connected everyday substances with ritual power.

That uncertainty makes the discovery more interesting, not less. It opens a conversation between chemistry, archaeology, economics and religion. More samples from securely dated objects may eventually show whether moringa clustered around certain places, periods, colors or funerary uses.

Why the Discovery Matters to Museums

Knowing a paint’s binder helps conservators predict how the surface may respond to humidity, heat, solvents and adhesives. Animal glue, egg and plant material can age differently. Moreover, a treatment that protects one component could soften, stain or weaken another.

The findings also warn against overly tidy classifications. A conservator cannot safely assume that every matte Egyptian paint uses the same gum or that every collagen signal came from cattle bone. Mixed proteins and unusual seed products may lurk in layers that look nearly identical to the naked eye.

Proteomics will not replace imaging, microscopy or conventional chemical analysis. Instead, it adds a powerful line of evidence. The researchers reached their seed-cake proposal only after combining protein data with infrared spectroscopy, molecular analysis and archaeological context. That multidisciplinary approach provides a model for future studies of fragile art.

Finally, the work restores some individuality to anonymous artisans. These painters did not merely fill outlined figures with standard colors. They chose, prepared and adjusted complicated materials. Their expertise lived in touch, timing and observation—knowledge that rarely entered royal inscriptions but still survives in the paint.

The Lost Recipe Is Beginning to Reappear

This study does not produce one universal formula for how ancient Egyptians made paint. Instead, it reveals a changing toolkit filled with cattle collagen, equid glue, egg and unexpected seed products. The evidence stretches across 1,800 years, so variation should not surprise us. Egyptian art remained visually distinctive because generations of craftspeople adapted materials while preserving powerful traditions.

Most importantly, the research turns a microscopic paint flake into a record of agriculture, animal use, oil production, religion and skilled labor. The ancient Egyptian paint ingredients now emerging from those flakes show that an artwork can preserve far more than an image. It can preserve the decisions that made the image possible.

Frequently Asked Questions

What did ancient Egyptians put in their paint?

Egyptian artists mixed colored pigments with binders such as plant gum, animal glue, egg or wax. The new study also found sesame and moringa seed proteins in some painted objects.

How did scientists identify the paint ingredients?

Researchers used mass spectrometry-based proteomics to identify peptide sequences from surviving proteins. They combined those results with infrared spectroscopy, pyrolysis-gas chromatography–mass spectrometry and archaeological evidence.

Did ancient Egyptians use sesame oil as paint?

The samples contained seed proteins and only traces of oil. Therefore, the researchers favor a protein-rich seed-processing byproduct, such as pressed seed cake, over pure sesame or moringa oil. The exact recipe remains unknown.

Which animals supplied Egyptian glue?

The study found cattle most often among samples with animal glue. It also identified sheep or goat, donkey, horse and possibly antelope sources. In several cases, tissue evidence pointed toward hides and connective tissues.

Why is moringa important in the discovery?

Moringa proteins had not previously been documented in ancient Egyptian artworks. The plant also had a possible cultural connection to Ptah, a god associated with craftspeople, although the proteins alone cannot prove a symbolic purpose.

Researchers did not identify famous authors, samurai, or noble families. Instead, the evidence most likely came from ordinary people who lived in the great publishing cities of Kyoto, Osaka, and Edo, now Tokyo. Their hair recorded the chemistry of rice, fish, salt, metal cookware, and urban pollution. Moreover, it challenged a familiar assumption. Although these commoners ate a diet centered heavily on rice and marine fish, their hair contained higher levels of several minerals than hair from modern Japanese comparison groups.

The discovery turns an old book into two archives at once. One archive preserves the words that printers placed on the page. The other preserves the people who helped make the paper.

When a Book Cover Contains a Stranger

Traditional Japanese books, or wahon, often used thin sheets for their printed pages and thicker recycled paperboard for their covers. Paper makers produced that board from discarded paper, which carried dust, fibers, and sometimes loose human hair. Workers may have mixed the hair into the pulp by accident during waste collection. Alternatively, some may have added strands deliberately to strengthen the recycled sheet.

Either route created an astonishing scientific opportunity. Cheap cover board rarely traveled far because transportation and storage cost money. Consequently, workshops usually collected, pulped, and reused waste paper within the same urban commercial network. A hair in a Kyoto cover probably came from Kyoto; a strand inside an Osaka book probably came from Osaka.

The book’s colophon supplied the next clue. Usually located near the final page, the colophon named a publisher, place, and year. However, woodblocks could print new copies for decades, so a publication year did not always equal the actual printing year. Bibliographic experts therefore examined wear, cracks, and other clues in the carved blocks to refine the dates.

No single strand came with a name. Nevertheless, many strands tied to many books could reveal population-level patterns that diaries, menus, and official records might miss.

From 70,000 Volumes to 104 Chemical Snapshots

The scale of the search makes this project remarkable. Atsushi Maruyama and his colleagues began with approximately 70,000 volumes, most housed at the Ryukoku University Omiya Library. The team then moved through several filters before running chemical tests. Published on August 17, the 2026 Scientific Reports study documents the process in detail.

Researchers found most of the usable books in the orbit of Kyoto, Osaka, and Edo. That pattern reflects the geography of commercial publishing, paper recycling, literacy, and urban leisure rather than the full population of Japan. Therefore, the results speak most clearly about urban commoners.

The team also compared the historical strands with 40 modern samples collected in 2020. That reference group included 15 Kyoto residents, 13 Osaka residents, and 12 Tokyo residents, with both sexes and several adult age groups represented. Researchers excluded vegetarians, vegans, and participants with close family origins outside Japan to reduce major dietary and geographic differences.

How Scientists Read a Single Hair

Hair grows by roughly one centimeter per month. As keratin forms, it locks in chemical and isotopic signals linked to diet and environmental exposure. Unlike bone, which can average many years of life, a hair strand can preserve a shorter window measured in months. That difference makes hair especially useful for studying everyday food patterns.

First, the team used particle-induced X-ray emission, or PIXE, to measure ten elements: silicon, sulfur, chlorine, potassium, calcium, manganese, iron, copper, zinc, and lead. Researchers gently cleaned each historical hair with ethanol, mounted it on a carbon holder, and aimed a focused proton beam at it. The resulting X-rays revealed the elements in the strand. PIXE requires no chemical digestion, and it leaves most of the sample intact.

Next came carbon and nitrogen stable-isotope analysis. The scientists cleaned those samples with a 2-to-1 chloroform-methanol solution, treated them ultrasonically for 10 minutes, and dried them at 60 degrees Celsius for at least 12 hours. Each test used about 0.55 to 0.65 milligrams of hair, usually equal to 8 to 12 centimeters of growth. An isotope-ratio mass spectrometer then measured carbon-13 and nitrogen-15 with precision better than plus or minus 0.2 parts per thousand.

Finally, all samples produced a mean carbon-to-nitrogen ratio of 3.09, with a standard deviation of 0.08. That result fits well-preserved keratin and supports the argument that the strands retained authentic biological signals.

What Ten Elements Revealed

The chemical comparison produced a striking split. Historical hair contained significantly more chlorine, potassium, calcium, manganese, iron, copper, and lead. In contrast, modern hair contained more sulfur and zinc. Silicon showed no statistically detectable difference between eras.

The table below lists the study’s era comparisons. A larger F statistic generally signals a stronger separation after the model accounts for location, although it does not measure nutritional benefit.

Location alone did not create a significant main effect for any element. Yet several smaller patterns appeared. Sulfur ran lower outside the three main cities, chlorine ran lower in Tokyo than Kyoto, and potassium ran higher in the provincial samples. In addition, manganese and chlorine showed modest era-by-city interactions. Iron moved downward over time in Kyoto but upward in Osaka, while copper increased in Kyoto and decreased in Tokyo.

These details matter because human hair found in old Japanese books does not point to one magical food. Instead, it records a changing system of agriculture, trade, processing, cooking, preservation, and personal habits.

A Simple Diet That Was Not Chemically Simple

Carbon and nitrogen isotopes revealed the broad menu behind the mineral results. In plants, different photosynthetic pathways produce different carbon-13 signatures. Rice, wheat, and most vegetables use the C3 pathway. Millet and foxtail millet use the C4 pathway. Meanwhile, nitrogen-15 generally rises higher in food webs, so marine fish often leave a stronger nitrogen-15 signal than staple plants.

Historical hair showed carbon-13 values 3.0 parts per thousand lower than modern Japanese hair after the researchers corrected modern values for the atmospheric changes caused by fossil-fuel emissions. Conversely, historical nitrogen-15 ran 1.4 parts per thousand higher. Both differences reached p values below 0.001.

Together, those values place rice and other C3 staples at the center of the urban diet, with marine fish supplying much of the nitrogen. The pattern also agrees with the team’s 2018 pilot study, which examined 24 secondhand book sets. Twenty-three supplied enough hair for isotope tests, and some covers held as many as roughly 1,000 fragments.

Interestingly, the pilot study found hair signatures between C3 plants and marine fish rather than near meat, dairy, tofu, or natto reference values. That result does not mean people never ate those foods. Instead, it means rice, vegetables, and fish dominated the average biochemical signal.

Rice Polishing Left a Timeline in Hair

Rice processing offers one of the clearest historical clues. Minerals concentrate heavily in the grain’s outer layers, so polishing removes silicon, potassium, calcium, manganese, iron, copper, and zinc along with the bran. As cities gained better milling infrastructure, highly polished white rice became easier to obtain and more desirable.

Across the historical samples, potassium declined sharply with time (t = -7.16; p < 0.001). Silicon also fell, although more modestly (t = -2.09; p = 0.039). Provincial samples carried more potassium than Kyoto samples, which suggests that intensive polishing reached major cities earlier or affected them more strongly.

Carbon isotopes tell a related story. Historical carbon-13 declined over time (t = -2.43; p = 0.016), indicating that C4 crops such as millet and foxtail millet gradually lost ground to C3 staples, especially rice. Consequently, the chemical record shows not a static “Edo diet,” but a food system moving steadily toward refined rice.

That transition carried a known danger. Heavy dependence on polished rice could strip away thiamine-rich bran and contribute to beriberi. People once called the disease Edo wazurai, or the “Edo affliction,” because visitors sometimes became sick while eating the city’s white-rice-heavy diet. The 2018 study even proposed that Edo residents may have eaten more millet than people in Kyoto or Osaka as a partial response.

Fish Reached Both the Dinner Bowl and the Rice Field

The nitrogen evidence moved in the opposite direction from millet. Nitrogen-15 increased significantly through the historical period (t = 4.97; p < 0.001), which points toward a growing role for marine fish. Expanding coastal fisheries and better transport networks made that trend historically plausible.

During the eighteenth century, highly productive sardine fisheries grew around Chiba. Herring fisheries expanded around Hokkaido during the nineteenth century. Ships and commercial routes then carried marine products toward large inland markets. Moreover, Osaka served as a crucial distribution hub for rice and other goods that moved between domains and major cities.

Fish may have reached human hair by two routes. People ate inexpensive species such as sardines and mackerel, gaining protein and minerals directly. Farmers also spread fish-derived fertilizer on paddy fields, potentially changing the isotopic and mineral composition of the rice itself.

The 75 book sets with both tests strengthen this interpretation. Higher nitrogen-15 correlated positively with manganese (t = 2.81; p = 0.006), iron (t = 2.16; p = 0.034), and copper (t = 2.22; p = 0.029). Those same elements failed to decline as rice polishing alone would predict. Therefore, marine resources may have compensated for some minerals lost when millers removed the bran.

Researchers cannot yet separate direct fish consumption from fish fertilizer. Future tests on historical rice could help solve that puzzle.

Salt Preserved Food—and Left a Powerful Signal

Before mechanical refrigeration, salt did far more than sharpen flavor. It protected fish and other foods from spoilage, supported fermentation, and helped urban markets move food across time and distance. Accordingly, chlorine produced one of the largest gaps between historical and modern hair.

Regional cuisine added another layer. Kyoto and Osaka developed traditions involving salt-fermented fish such as narezushi and the relatively salty usukuchi soy sauce. Tokyo depended heavily on salt shipped from the Seto Inland Sea, so price and supply could shape how residents used it. By 1879, the Seto Inland Sea region supplied about 80 percent of Japan’s salt output, according to the historical data assembled in the study.

A negative relationship also appeared between carbon-13 and chlorine (t = -2.98; p = 0.004). However, the researchers warn against treating that link as a direct biological mechanism. Geography affected both variables, so the correlation may reflect regional combinations of rice dependence and salt use.

High chlorine does not prove a healthier diet. On the contrary, it may document heavy salt exposure created by life before refrigeration.

Cookware, Cosmetics, and the Chemistry Around Dinner

Not every element came directly from a meal. Iron and copper cookware can transfer small amounts of metal into food, especially during long cooking or contact with acidic ingredients. Thus, pots and vessels offer a plausible explanation for part of the elevated iron and copper signal. City-specific changes in those elements may even reflect different local paths in household technology.

Lead tells a darker story. The researchers connect high historical lead most plausibly to oshiroi, a white cosmetic powder that often contained lead. Earlier osteoarchaeological research found severe lead contamination among some Edo-period children from samurai families. Other urban sources may have contributed as well. Either way, lead in the hair represents toxic exposure, not dietary quality.

Zinc moved in the modern direction. Today’s comparison samples contained significantly more zinc, which the authors link cautiously to greater consumption of beef and pork. Cultural taboos and formal restrictions kept mammalian meat relatively uncommon before the Meiji era. Later westernization added more meat to Japanese diets, and both beef and pork supply substantially more zinc than rice-based staples and many fish products.

Did Edo-Era Commoners Eat a Healthier Diet?

No—not as a conclusion from this study.

Hair chemistry does not equal a food diary, a blood test, or a medical diagnosis. Hair holds the fraction of an element that remains after the body absorbs, uses, and excretes it. Therefore, twice as much of an element in hair does not mean someone ate exactly twice as much. External exposure can also affect a strand, even though the team cleaned the samples and found traditional papermaking materials unlikely to explain the broad pattern.

Furthermore, more is not always better. Calcium, iron, copper, and manganese perform essential biological roles, but excessive exposure can cause harm. Chlorine likely reflects a salt-heavy preservation system, while lead clearly marks a hazard. Modern zinc levels ran higher, and modern diets also draw from a much wider range of foods.

The responsible takeaway is narrower and more interesting: a diet can look simple on a menu while remaining chemically complex. Food processing, soil amendments, fisheries, preservation, and cookware can change mineral availability just as powerfully as the number of foods on the plate.

The Limits of the Book-Hair Archive

Several unanswered questions remain. First, the hairs lacked roots, so DNA probably cannot reveal reliable sex or individual identity. A single book cover may also contain strands from several people. Consequently, each set works best as a community-level signal rather than a personal biography.

Survival creates another bias. Urban books from Kyoto, Osaka, and Tokyo dominate the collection, while rural communities appear far less often. In addition, a later owner could have replaced a cover, and a colophon could preserve the publication date rather than the precise printing date. Bibliographic correction reduces those problems but cannot erase them.

The instruments imposed limits too. Overlapping X-ray peaks prevented reliable measurements of sodium, magnesium, bromine, and mercury. Strontium usually fell below the quantification limit, especially in modern samples. Meanwhile, PIXE measured each fragile hair only once.

Finally, the team cannot yet calculate exact historical nutrient intake or decide how much manganese, iron, and copper came from fish, fertilizer, cookware, or some combination. The results support those mechanisms, but they do not close the case.

Libraromics: The Science Waiting on a Shelf

The researchers use a fitting word for this work: libraromics. It means studying biological material preserved inside books and other cultural objects. Hair, skin cells, insect remains, microbes, plant fibers, proteins, and chemical residues can all turn a physical volume into a scientific archive.

Books offer several advantages over bones and teeth. Libraries hold enormous collections with dates, locations, editions, and ownership clues. Researchers can often remove an exposed hair with forceps while causing almost no damage. Furthermore, book sampling avoids many ethical concerns that arise when scientists excavate or test human remains.

Digitization preserves a book’s words, but a scan cannot capture every molecule in its paper, glue, stains, fibers, and covers. As a result, the physical object may contain evidence that nobody thought to seek when the text first entered a database.

That idea changes how we look at a dusty shelf. A cover is no longer merely protection for the pages. It may hold an environmental sample, a fragment of material culture, and an anonymous human witness—all waiting for the right question.

The People Are Still There

The study of human hair found in old Japanese books brings ordinary people closer than many official histories can. They did not leave names in the margins. Still, their bodies recorded the spread of polished rice, the growth of coastal fisheries, the reach of salt merchants, the metal in cooking pots, and the hidden cost of lead cosmetics.

Most importantly, the research shows how a culture leaves evidence in places nobody planned to preserve. Printers wanted sturdy, affordable covers. Paper makers wanted to reuse scraps. Centuries later, those practical decisions created a biological archive of urban Japanese life.

At first glance, a potato hardly looks capable of changing civilization. It has no brilliant rind, sweet fragrance or exotic shape. Instead, it hides beneath the soil like a buried stone. However, that modest appearance conceals a food packed with carbohydrates, potassium, vitamin C and agricultural potential.

Few crops produce so much food on so little land. Moreover, people can boil, bake, mash, fry, freeze, dry, ferment or distill potatoes. Manufacturers also transform potato starch into adhesives, medicines, textiles and biodegradable materials.

Consequently, the potato may deserve the title of the world’s most versatile vegetable. Botanically, though, it is not a root at all.

The Potato Is a Tuber, Not a Root

The common potato, Solanum tuberosum, belongs to the nightshade family. Tomatoes, peppers, eggplants and tobacco belong to the same botanical family.

Although people often call potatoes root vegetables, the edible portion is technically a tuber. A tuber is a swollen underground stem that stores energy for the plant. The small indentations called “eyes” are buds. Given suitable conditions, each eye can sprout and produce another plant.

Farmers usually grow potatoes from whole tubers or cut pieces known as seed potatoes. Therefore, many commercial potato plants are genetic clones of their parent plants. This method produces predictable crops, but it can also create widespread vulnerability to disease.

Sweet potatoes create another source of confusion. Despite their name, sweet potatoes are not close relatives of ordinary potatoes. They belong to the morning-glory family, and their edible portion is a true storage root.

Meanwhile, the potato plant produces leaves, flowers and small tomato-like berries above ground. Those berries are not edible. Green tubers and sprouts can also contain elevated concentrations of glycoalkaloids, including solanine. For that reason, people should avoid eating potatoes that have become heavily green, bitter or badly sprouted.

Where Did Potatoes Come From?

The potato originated in the Andes Mountains of South America, especially the highlands surrounding Lake Titicaca in present-day Peru and Bolivia.

According to the Food and Agriculture Organization of the United Nations, Indigenous communities began domesticating wild potatoes approximately 8,000 years ago. Genetic research suggests the process may have started between 8,000 and 10,000 years ago.

The environment presented enormous challenges. Farmers faced thin air, cold nights, powerful sunlight and sudden frosts. Nevertheless, wild potatoes grew where many other food plants struggled.

Ancient farmers gradually selected plants with larger tubers, improved flavors and lower concentrations of bitter compounds. At the same time, they developed varieties suited to particular elevations, soil types and weather patterns. This work created an extraordinary reservoir of agricultural diversity.

The International Potato Center reports that the Andes contain more than 4,000 native potato varieties and over 180 wild potato species. These potatoes appear in white, yellow, red, orange, blue, purple and nearly black. Some look smooth and round, while others have twisted, knobby shapes.

In contrast, most supermarkets outside South America sell only a handful of commercial varieties. The difference reveals how much potato diversity remains unfamiliar to much of the world.

How Andean Communities Preserved Potatoes

Growing a dependable crop solved only part of the food problem. Families also needed to preserve their harvest through severe winters and occasional crop failures.

As a result, Andean communities developed chuño, one of the world’s earliest freeze-dried foods. Farmers spread small potatoes outside during freezing mountain nights. During the day, strong sunlight thawed and dried them. People then crushed or trampled the potatoes to remove moisture.

Repeating the process produced a lightweight, hard and shelf-stable food. Properly stored chuño could remain usable for years without refrigeration. Families rehydrated it for soups, stews and porridges.

Furthermore, chuño provided protection against famine. Communities could store surplus potatoes during productive seasons and use them after a poor harvest. Inca administrators also collected preserved foods and stored them in government warehouses.

Potatoes and chuño supported travelers, laborers and armies moving through the enormous Inca road system. Therefore, the potato was not merely another vegetable. It became part of the economic and political foundation of Andean civilization.

Together, the history and uses of potatoes reveal an important truth: Indigenous agricultural knowledge created the crop that later transformed much of the world.

How the Potato Reached Europe

Spanish expeditions encountered potatoes after entering the Andes during the sixteenth century. Soldiers and administrators quickly recognized their importance to local communities.

Eventually, Spanish sailors carried the tubers across the Atlantic. Farmers began growing potatoes in Spain during the latter half of the 1500s. From there, botanists, merchants, soldiers and sailors distributed them across Europe.

However, Europeans did not immediately embrace the unfamiliar crop. The potato plant resembled poisonous nightshades, which encouraged suspicion. In addition, the Bible did not mention potatoes, and they did not fit comfortably into established farming traditions.

Some Europeans grew potato plants as ornamental curiosities. Others believed the tubers caused disease or encouraged immoral behavior. Such fears sound strange today, yet unfamiliar foods often attract rumors.

Nevertheless, sailors appreciated potatoes because they traveled well and provided vitamin C. Farmers also noticed that the plants produced substantial harvests on land that yielded poor grain crops.

By the eighteenth century, food shortages and recurring wars encouraged governments to promote potato cultivation. Frederick the Great pushed Prussian farmers to grow them. Meanwhile, French pharmacist and agricultural reformer Antoine-Augustin Parmentier used public dinners, scientific arguments and royal connections to improve the potato’s reputation in France.

Gradually, suspicion gave way to necessity. The strange Andean tuber became a European staple.

The Potato’s Journey Through History

The Crop That Helped Build Modern Europe

Potatoes offered several advantages over wheat, rye and other grains. First, they produced considerable food on small plots. Families could support themselves on less acreage, which mattered greatly in crowded rural communities.

Additionally, tubers grew underground. Passing armies could burn grain fields or seize stored wheat, but potatoes often remained hidden beneath the soil. Farmers could also harvest them as needed instead of gathering the entire crop at once.

Potatoes required less processing than grain. A family needed a mill to turn wheat or rye into flour. In comparison, they could dig up a potato and cook it directly in a fire or pot.

Most importantly, potatoes supplied dependable calories. A relatively small patch could support a large family when combined with milk, vegetables or small amounts of meat.

Consequently, historians have connected the spread of potatoes with European population growth. Better access to calories reduced the frequency of local hunger and helped more children survive. Growing populations then supplied workers for expanding towns, mines and factories.

The FAO’s International Day of Potato describes the crop as a contributor to urbanization and the Industrial Revolution. While no single food created modern Europe, potatoes made rapid growth easier to sustain.

However, dependence created a dangerous weakness. Ireland would experience that danger more severely than anywhere else.

The Irish Potato Famine

By the early nineteenth century, millions of poor Irish families depended heavily on potatoes. Tenant farmers often worked small plots and paid rent to landowners. Potatoes produced enough food to support families on acreage too limited for grain or livestock.

A diet of potatoes and milk could supply a surprising range of nutrients. Nevertheless, dependence on one crop left families exposed to disaster.

In 1845, the organism Phytophthora infestans spread through Irish potato fields. Commonly known as late blight, it blackened leaves and caused tubers to rot. The disease returned during subsequent seasons and destroyed much of the crop.

Ireland also relied on a narrow genetic base. Because farmers planted similar varieties, the blight encountered little resistance. Instead of stopping at isolated fields, it swept through entire regions.

Still, plant disease alone does not explain the catastrophe. Poverty, tenant farming, food exports, government policies and an inadequate relief response intensified the suffering. Ireland continued producing other foods, but many poor families could not afford them.

Between 1845 and 1852, starvation and disease killed more than one million people. More than one million others emigrated, particularly to the United States, Canada, Britain and Australia. The Government of Ireland describes the period as one of mass death, displacement and emigration.

The Great Famine permanently changed Ireland’s population, language and culture. It also transformed cities across North America as Irish immigrants established new communities.

Moreover, the disaster taught agricultural scientists a lasting lesson: relying on a genetically uniform crop can turn disease into catastrophe.

How Potatoes Spread Around the World

Europeans carried potatoes to their colonies, trading partners and military outposts. By the seventeenth century, the crop had reached India. It later spread through China, Japan, Africa, North America and the Pacific.

Different regions adopted it for different reasons. Mountain communities valued its ability to tolerate cool temperatures. Farmers in densely populated areas appreciated its high yield. Cities created profitable markets for fresh potatoes and prepared foods.

During China’s Qing Dynasty, potatoes helped communities cultivate highlands and marginal land where rice struggled. Likewise, farmers in India developed major potato-growing regions in cooler northern states.

European settlers introduced South America’s potato to North America by way of Europe. Therefore, the crop completed a curious round trip through the Columbian Exchange.

During the twentieth century, processing reshaped the market. Manufacturers produced dehydrated flakes, potato chips and frozen french fries on an enormous scale. Fast-food restaurants then turned the french fry into a global product.

Today, developing countries produce more than half of the world’s potatoes. Asia now leads global production, even though South America remains the crop’s ancestral homeland.

What Are Potatoes Used For?

The potato’s versatility explains much of its success. Cooks can transform the same basic ingredient into hundreds of dishes with completely different flavors and textures.

Potatoes as Food

Few ingredients can match the potato’s culinary range. Waxy varieties hold their shape in soups, stews and salads. Meanwhile, starchier russets produce fluffy baked potatoes, smooth mashed potatoes and crisp fries.

Cooks can roast small potatoes with herbs, layer sliced potatoes into gratins or combine them with meat and vegetables in casseroles. Cultures around the world also use potatoes in curries, flatbreads, dumplings and filled pastries.

Food companies process large quantities into chips, frozen french fries, hash browns and dehydrated flakes. In fact, about two-thirds of American potato sales go to processing rather than the fresh table market.

Potato starch has its own culinary value. It thickens sauces, adds crispness to fried coatings and improves the texture of gluten-free baked goods. Manufacturers also use it in noodles, candies, soups and processed meats.

Distillers can convert the potato’s starch into fermentable sugar. Although most modern vodka comes from grain, some producers still make distinctive potato vodka. Irish poitín and several regional spirits have also used potatoes.

Therefore, the potato functions as a vegetable, staple carbohydrate, processed-food ingredient and fermentation source.

Uses Outside the Kitchen

Potatoes have an equally surprising industrial life. Manufacturers extract starch from lower-grade potatoes and processing waste. They then modify that starch for specialized products.

Paper companies use potato starch to strengthen paper and improve its surface. Textile manufacturers apply it during sizing and finishing. Wood-product companies incorporate starch into certain adhesives.

Pharmaceutical companies may use potato starch as a binder or filler in tablets. It can also help a tablet break apart after someone swallows it.

Furthermore, researchers and manufacturers have developed starch-based packaging and biodegradable plastics. These products cannot replace every petroleum-based plastic, but they offer promising applications.

Potatoes can also produce fuel-grade ethanol. Meanwhile, farmers feed rejected potatoes, peels and other processing leftovers to livestock when appropriate.

The International Potato Center’s guide to potato processing identifies glue, animal feed, ethanol, pharmaceuticals, textiles, wood products and paper among the crop’s nonfood uses.

Modern processing facilities increasingly recover starch, protein and energy from material once treated as waste. As a result, one potato may contribute to several products before anything reaches a landfill.

Are Potatoes Nutritious?

An ordinary potato contains more nutritional value than its reputation suggests. A medium potato with its skin provides approximately 110 calories, 26 grams of carbohydrates and about three grams of protein.

Potatoes also supply potassium, vitamin C and vitamin B6. The skin and flesh provide fiber, although the exact amount varies by size and preparation.

Naturally, potatoes contain little fat and no cholesterol. However, preparation can dramatically change the final dish. Deep frying adds fat and calories, while cheese, butter, sour cream and bacon can turn a modest potato into a much heavier meal.

Boiled, baked or roasted potatoes can fit comfortably into a balanced diet. Pairing them with vegetables and a protein source creates a more complete meal.

Cooling cooked potatoes also changes some of their starch into resistant starch. This form resists digestion in the small intestine and can act somewhat like dietary fiber.

Ultimately, the potato itself is not nutritional trouble. Portion size, cooking method and toppings often matter more.

How Many Pounds of Potatoes Are Grown Each Year?

The latest complete FAOSTAT dataset reports that farmers produced approximately 390,428,972 metric tonnes of potatoes worldwide in 2024.

That equals:

Approximately 860.7 billion pounds of potatoes grown worldwide

Farmers harvested those potatoes from about 17.1 million hectares, or approximately 42.2 million acres. Asia produced 205.4 million metric tonnes, representing 52.6% of the global harvest.

The figures come from the FAOSTAT production database and its 2024 regional potato totals.

China and India rank among the largest national producers. Together, they account for a substantial share of the world’s crop.

The United States produced an estimated 413 million hundredweight in 2025. Because one hundredweight equals 100 pounds, that harvest totaled approximately:

41.3 billion pounds of potatoes grown in the United States

Idaho produced roughly one-third of the American crop. Washington ranked second, while Wisconsin followed among the leading states. The USDA National Agricultural Statistics Service also reported record or near-record yields in several producing states.

How Many Pounds of Potatoes Are Consumed?

Measuring consumption presents a challenge. Agricultural agencies usually calculate the amount available within the food supply. They do not weigh every potato that people actually swallow.

Worldwide potato consumption averaged approximately 33.3 kilograms per person annually during 2017–2021. That equals about 73.4 pounds per person.

Applied to the global population during that period, the figure represents approximately:

570 billion pounds supplied for human consumption each year

Consumption varies dramatically by region. Europe averaged roughly 167 pounds per person annually, while Africa averaged about 32 pounds. Several Eastern European countries consumed far more than the global average. These figures appear in an agricultural study indexed by FAO AGRIS.

In the United States, preliminary 2025 availability reached 112 pounds per person, expressed in fresh-potato equivalents. With a population of approximately 341.8 million, that represents around:

38.3 billion pounds available to American consumers annually

However, food availability does not equal food eaten. Restaurants, grocery stores and households discard some of the supply.

The USDA’s latest loss-adjusted figure ends in 2019 because the agency no longer receives all the information needed for newer calculations. That estimate placed American consumption after losses at 49.4 pounds per person. Frozen potatoes, especially french fries, represented a significant portion of the total. USDA Economic Research Service

Why Production and Consumption Totals Differ

The world grows substantially more potatoes than people directly consume. However, the remaining potatoes do not simply disappear.

Farmers reserve part of the harvest as seed potatoes. Processors turn another portion into starch, alcohol, animal feed and industrial products. Storage losses, damaged crops and household waste reduce the amount that reaches a dinner plate.

International trade also complicates national statistics. A country may grow potatoes, export them for processing and later import frozen fries or potato starch.

Furthermore, agencies convert chips, flakes and frozen products into fresh-potato equivalents. That method allows comparisons, but it does not represent the weight of the final packaged food.

Therefore, global production and consumption figures answer different questions. Production measures the harvested crop, while food availability estimates how much enters the human food supply.

Potato Diversity and the Future of Food

The Irish Famine demonstrated the danger of planting genetically similar crops across enormous areas. Modern agriculture has not completely eliminated that risk.

Late blight still threatens potato farms. Viruses, insects, heat, drought and changing rainfall patterns create additional challenges. Because farmers reproduce many potatoes as clones, harmful diseases can move through genetically uniform fields quickly.

Fortunately, the Andes preserve an extraordinary genetic library. Wild species and traditional varieties may contain natural resistance to drought, frost, heat, insects and disease.

The International Potato Center maintains more than 7,000 potato accessions in its genebank. Researchers use this material to develop improved varieties while preserving irreplaceable diversity.

Additionally, potatoes can produce large quantities of food with relatively modest land and water requirements. The International Potato Center reports that one hectare can yield two to four times the food quantity of grain crops. Potatoes can also produce more food per unit of water than many major crops.

For these reasons, scientists view the potato as an important food-security crop. Improved varieties could help farmers feed growing populations under increasingly difficult conditions.

Frequently Asked Questions About Potatoes

Where did potatoes originally come from?

Potatoes originated in the Andes Mountains of South America. Indigenous communities around Lake Titicaca in present-day Peru and Bolivia began domesticating them approximately 8,000 years ago.

Is a potato a root?

No. A potato is a tuber, which is a swollen underground stem. Its eyes are buds capable of producing new plants.

Are potatoes and sweet potatoes related?

They are not close relatives. Ordinary potatoes belong to the nightshade family, while sweet potatoes belong to the morning-glory family.

How many pounds of potatoes does the world grow annually?

The world produced approximately 390.4 million metric tonnes in 2024. That equals about 860.7 billion pounds.

How many pounds of potatoes does the United States grow?

The United States produced an estimated 413 million hundredweight in 2025, or approximately 41.3 billion pounds.

How many potatoes does the average person consume?

The global average during 2017–2021 was approximately 73.4 pounds per person annually. American food availability reached about 112 pounds per person in 2025 before adjusting for waste.

What are potatoes used for besides food?

Industries use potato starch in paper, textiles, adhesives, wood products, medicines and biodegradable materials. Producers can also convert potatoes into livestock feed and fuel-grade ethanol.

The Humble Tuber That Changed the World

The potato began as a wild mountain plant. Indigenous farmers then transformed it into a dependable crop capable of surviving one of the planet’s most demanding agricultural environments.

Later, Spanish ships carried it across the Atlantic. European farmers initially mistrusted it, but food shortages eventually overcame their suspicion. Potatoes then supported population growth, urbanization and industrial development.

Unfortunately, Ireland’s Great Famine revealed the terrible consequences of poverty, political failure and dependence on a genetically narrow crop. That tragedy changed Ireland and reshaped communities across the Atlantic.

Today, potatoes appear everywhere from family gardens and restaurant kitchens to paper mills, pharmaceutical factories and research laboratories. The world grows more than 860 billion pounds annually, yet the crop’s greatest genetic diversity remains rooted in its Andean homeland.

After exploring the history and uses of potatoes, it becomes difficult to call the potato humble. Few foods have fed so many people, inspired so many recipes or influenced civilization so deeply.

Astronomers call the object MoM-BH*-1. Its light began traveling toward us only 660 million years after the Big Bang, when the universe had reached less than five percent of its current age. Although the source appears as little more than a red point in a Webb image, its spectrum carries a much stranger story. The object looks compact and star-like, but no ordinary collection of stars can easily produce its extraordinary pattern of light.

That pattern may also solve a larger mystery. Since JWST began science operations, it has uncovered a surprisingly abundant population of compact crimson objects in the early universe. Researchers nicknamed them “little red dots,” or LRDs. Some appear to contain active black holes, but they often lack the X-rays, dust glow, and other features that astronomers expect from familiar quasars.

Now, MoM-BH*-1 offers scientists something close to a clean view of the engine. Its possible host galaxy contributes remarkably little to the light that Webb detects. Consequently, researchers can study the central source without having to untangle it from the glare of billions of surrounding stars. If their interpretation holds, the tiniest dots in Webb’s images may expose one of the biggest missing chapters in cosmic history.

JWST’s Little Red Dots Refused to Behave

When JWST opened its infrared eyes, astronomers expected to find young galaxies. Instead, they also encountered numerous sources that looked extremely small, unusually red, and surprisingly bright. The dots emerged in large numbers roughly 600 million years after the Big Bang, while their population declined dramatically by about 1.5 billion years after it.

At first, several explanations seemed possible. Perhaps the objects were mature galaxies packed with more stars than early-universe models predicted. Alternatively, dust might surround feeding supermassive black holes and absorb their blue light. Some researchers even proposed vast primordial stars, dense stellar clusters, or other short-lived phenomena.

However, every simple answer created another problem. If old stars supplied the light, how had so many galaxies matured so quickly? If dust caused the red color, why did many dots produce so little of the expected infrared glow? Meanwhile, if actively feeding black holes powered them, why did most remain faint or invisible in X-rays?

Their spectra deepened the puzzle. Many LRDs show broad hydrogen emission lines, which usually signal gas racing around a massive black hole. Nevertheless, they also show sharp changes in brightness that resemble stellar atmospheres or older populations of stars. In effect, the dots mix traits that astronomers normally file in different drawers.

MoM-BH*-1 matters because it turns those conflicting clues into parts of one physical object. Instead of placing a dusty quasar behind a separate population of stars, the new model wraps the accreting black hole itself in a thick hydrogen envelope. That gas then absorbs, scatters, and reprocesses the central light until the entire structure resembles a colossal stellar atmosphere.

Meet MoM-BH*-1, the Reddest Target in the Field

The name begins with “Mirage or Miracle,” the JWST survey that selected the source for close inspection. That project deliberately pursued risky targets—objects that might reveal something extraordinary or turn out to be misleading foreground interlopers. MoM-BH*-1 certainly earned its place on the list.

In NIRCam images of a roughly 250-square-arcminute field, it stood out as the reddest source. Webb detected the object clearly in longer-wavelength infrared filters, yet it seemed to vanish in the bluer ones. Moreover, the source remained unresolved, meaning the telescope saw a point rather than a clearly extended galaxy.

Researchers then examined it with JWST’s Near-Infrared Spectrograph, or NIRSpec. A spectrum separates light by wavelength, much as a prism spreads white light into a rainbow. However, astronomical spectra do far more than reveal color. Their peaks, valleys, and missing bands identify chemical elements, gas density, motion, temperature, and the physical processes that produce the light.

The NIRSpec data fixed the object at a redshift of about 7.76. In practical terms, we see it as it appeared approximately 660 million years after the Big Bang. Its compact glow therefore reaches us from “cosmic dawn,” the era when the first generations of galaxies and black holes began transforming the universe.

Most importantly, the spectrum revealed broad hydrogen-beta emission, deep hydrogen absorption, and an enormous Balmer break. Together, those features resist an ordinary stellar explanation. They instead point toward extremely dense gas surrounding an energetic central engine.

What Is a Black Hole Star, Exactly?

Despite the catchy label, the proposed object is not a star with a black hole simply sitting where its core should be. Nor is it a black hole somehow glowing on its own. Black holes remain dark; the violence occurs in the material around them.

Gas falling inward carries angular momentum, so it usually forms a fast-spinning accretion disk. Friction, magnetic fields, and compression heat that material until it radiates tremendous energy. In a conventional active galactic nucleus, much of this radiation escapes directly from the disk and its immediate surroundings.

MoM-BH*-1 may add another layer. The researchers modeled a central accretion disk inside gas with exceptional density and turbulence. Their representative model used hydrogen densities around 100 billion particles per cubic centimeter, a very large gas column, and turbulent speeds near 500 kilometers per second. Furthermore, the envelope extended across roughly 10 to 100 astronomical units—on the scale of our solar system rather than a normal stellar atmosphere.

Light from the inner accretion flow must pass through this cocoon. Along the way, hydrogen atoms absorb some wavelengths, scatter photons, and release energy at other wavelengths. Therefore, Webb does not see a standard quasar spectrum. It sees the reprocessed glow of a black hole wearing an atmosphere.

Astronomers have used related terms such as “quasi-star” for theoretical black holes embedded inside massive gaseous envelopes. The new phrase emphasizes the observed spectral resemblance to a star. Still, the researchers do not claim that MoM-BH*-1 fits every older quasi-star model. They use the label as a physical picture for an unusual, gas-enshrouded stage of black-hole growth.

The Balmer Break: A Cosmic Fingerprint

The strongest clue hides in a sudden cliff in the spectrum. Hydrogen atoms can absorb photons when their electrons jump between energy levels. Near the Balmer limit, this process can create a noticeable break between the amount of light on the red and blue sides of a particular wavelength.

Normal stellar populations can produce Balmer breaks. For example, A-type stars show prominent versions because their atmospheres contain many hydrogen atoms with electrons in the right excited state. Even so, stellar models have limits.

MoM-BH*-1 blows past them. The research team measured a Balmer-break strength near 7.7. By comparison, a typical dust-free stellar population should remain below about 3, while even an extreme population made entirely of A-type stars should remain below 5. In addition, the observed flux dropped by more than a factor of 20 between two Webb infrared bands.

Deep absorption in hydrogen-beta and hydrogen-gamma strengthened the case. To create those features, the gas must pack hydrogen atoms densely enough to keep large numbers of electrons in an excited energy level. The team estimated a density of at least a billion hydrogen particles per cubic centimeter, while its preferred model went much higher.

At the same time, MoM-BH*-1 produces very broad hydrogen emission. Its hydrogen-beta line spans thousands of kilometers per second, a hallmark often associated with gas near an active supermassive black hole. The spectrum therefore shows absorption and emission together—an unusual combination that suggests a bright central source buried inside its own thick atmosphere.

Notably, the research team tested nearly a million simplified gas models. A dense, turbulent, almost dust-free envelope reproduced the major features: the dramatic break, the hydrogen lines, the weak ultraviolet light, and the longer-wavelength signal recorded by Webb’s Mid-Infrared Instrument. The fit does not prove the model, but it demonstrates that one physical framework can explain several mysteries at once.

Gas, Not Dust, May Make the Dot Red

Cosmic redness usually encourages astronomers to suspect dust. Tiny grains absorb and scatter shorter, bluer wavelengths more strongly, allowing redder light to dominate. The same broad idea colors a smoky sunset on Earth.

Yet heavy dust creates heat and should reradiate substantial energy at longer infrared wavelengths. Little red dots often fail to show enough of that far-infrared output. MoM-BH*-1 likewise fits a model with very little dust extinction—about 0.15 magnitude instead of the much larger values used in some earlier interpretations.

Dense hydrogen provides another route. Rather than merely dimming an otherwise familiar spectrum, the gas changes the spectrum’s shape. It suppresses ultraviolet light below the Balmer break, scatters photons, and produces the complicated hydrogen-line pattern. As a result, the object can look extremely red without hiding behind a conventional dusty curtain.

That distinction could change estimates of black-hole masses. Astronomers commonly infer mass from the brightness and width of broad emission lines using relationships calibrated on nearby active galaxies. However, scattering inside an exotic envelope can broaden a line without requiring gas to orbit at the speed assumed by those formulas. Likewise, correcting for dust that is not actually present can inflate the estimated luminosity.

The Nature study concludes that standard methods could overestimate the masses of some LRD black holes by factors of 10 to 100. Depending on the assumptions, the team’s estimates for MoM-BH*-1 span roughly one million to tens of millions of solar masses. Their envelope model favors a value near two million solar masses if the object radiates close to its Eddington limit. Therefore, the finding may not reveal impossibly oversized black holes; instead, it may reveal how unfamiliar gas physics made astronomers weigh them incorrectly.

The Race to Build a Supermassive Black Hole

Even revised masses leave astronomers with a difficult timing problem. The early universe produced quasars powered by black holes approaching a billion solar masses within its first 700 million to 800 million years. Somehow, relatively small “seed” black holes formed, found enormous fuel supplies, and grew at a breathtaking pace.

Ordinary accretion faces a natural speed limit. As matter falls inward, it radiates energy. That outward radiation pushes against the next wave of infalling gas. Eventually, the pressure can balance gravity at a threshold known as the Eddington limit.

However, a dense envelope may change the contest. If thick gas traps radiation or carries energy away through convection, outward pressure cannot halt the inflow as efficiently. Consequently, gravity may continue pulling material inward at a super-Eddington rate. Brief episodes of such rapid feeding could help a young black hole gain mass faster than standard models allow.

MoM-BH*-1 may capture that growth phase—or its immediate aftermath. The cocoon could represent the reservoir that feeds the black hole while also hiding many familiar signs of an active nucleus. Moreover, the object’s faint host appears to contain fewer than about 300 million solar masses in stars, which makes the central engine especially conspicuous.

A larger neighboring galaxy lies roughly 60,000 parsecs away in projection at nearly the same redshift. That environment may also matter. Some direct-collapse models require a nearby source of intense radiation to prevent primordial gas from cooling and fragmenting into ordinary stars. Instead, the gas can collapse into a much heavier black-hole seed. The current evidence does not establish that origin, but the nearby galaxy offers an intriguing clue.

One Object May Connect the Little Red Dots

MoM-BH*-1 appears unusual because its central engine overwhelms nearly every other source of detected light. Most LRDs probably mix light from an active center with light from a surrounding galaxy. That mixture makes each component difficult to identify.

The researchers turned this difference into a test. Models indicate that MoM-BH*-1 and its brighter neighbor could merge in roughly 100 million years. When the team combined their observed spectra, the result resembled a typical little red dot: blue or ultraviolet light from star formation, red optical light from the enshrouded black hole, a V-shaped spectral energy distribution, and broad hydrogen features.

In other words, MoM-BH*-1 may provide an almost pure template for the hidden engine. Add a young host galaxy, and the familiar LRD pattern emerges. Variations in gas density, host brightness, star-formation history, and viewing angle could then explain why the wider population does not look identical.

The thick envelope may even explain the missing X-rays. Gas with a huge column density can block energetic photons that would normally reveal a feeding black hole. Meanwhile, the lack of heavy dust accounts for weak far-infrared emission. Thus, two supposed objections to the black-hole interpretation become expected consequences of the same cocoon.

Other Webb observations also support gas-enshrouded engines in at least some LRDs. For example, spectra of objects such as GLIMPSE-17775 show multiple features consistent with a rapidly accreting black hole inside a dense gas shell. Still, astronomers should not assume that every red point shares one identity. The LRD label describes an appearance, and nature often creates similar appearances through different processes.

A Compelling Model, Not a Final Verdict

The phrase “shouldn’t exist” makes a great headline, but the universe has not violated physics. Instead, MoM-BH*-1 challenges the familiar categories and assumptions that astronomers built from nearby objects. Early cosmic environments contained different gas supplies, lower levels of heavy elements, and far more rapid growth.

Several uncertainties remain. First, researchers cannot photograph the event horizon or directly map the proposed atmosphere at this distance. They infer the structure from its spectrum. Second, the paper’s gas model deliberately simplifies a complicated three-dimensional system. The authors note that the accretion disk, convection, geometry, and radiative transfer may differ from their assumptions.

In addition, Chandra has not detected MoM-BH*-1 in X-rays. A Compton-thick gas envelope could explain that silence, but a nondetection cannot independently confirm the black hole. The host galaxy and exact mass also remain uncertain.

Alternative explanations for the broader LRD population have not disappeared. Some researchers continue to examine supermassive stars, dense stellar systems, unusual dust, and other transient stages. Indeed, different objects may demand different answers. Science advances by forcing competing models to make predictions that new observations can test.

Future Webb programs can search for more sources with the same extreme spectral fingerprint. Astronomers can also measure changes in brightness, refine the hydrogen-line shapes, constrain the envelope’s size, and look for radio, X-ray, or infrared signals. If multiple objects repeat the pattern, the proposed class will move from a fascinating interpretation toward a durable part of astrophysics.

A Red Dot With an Enormous Story

So, what is a black hole star? The best current answer describes a rapidly feeding black hole buried inside a solar-system-scale cocoon of extraordinarily dense gas. That envelope reprocesses the central engine’s light until the object mimics features of a stellar atmosphere, even though ordinary stars cannot explain its full spectrum.

MoM-BH*-1 gives astronomers a rare look at that hidden engine almost without the usual glare of a host galaxy. Therefore, it may connect JWST’s little red dots to the frantic childhood of supermassive black holes. It could also show that some early black holes were smaller than previous estimates, yet grew under far stranger conditions than nearby examples reveal.

Most importantly, the discovery captures why cosmic dawn remains so exciting. Webb does not merely push familiar objects farther into the distance. It reaches an era in which the universe assembled new structures through conditions we have never observed close to home.

For generations, popular accounts portrayed the precolonial Amazon as a nearly untouched wilderness. According to that old story, scattered bands of people lived lightly along the rivers while the vast interior remained mostly empty. However, a major study published in Nature on July 29, 2026, delivers a powerful challenge to that picture. Researchers used airborne LiDAR to document 432 earthworks in southwestern Amazonia, and only 36 of them were previously known. Their results suggest that the wider region may contain between 24,000 and 30,000 structures. Moreover, the researchers estimate that 1.25 million to 3 million people could have lived there at the civilization’s peak.

Importantly, the discovery does not prove that a single forgotten empire ruled the rainforest. Nor did scientists suddenly find stone temples rising beneath the canopy. Instead, the research exposes a vast network of communities that built monumental gathering places, connected landscapes, cultivated crops, managed forests, and left marks that still influence the Amazon today. The rainforest was not empty, and its human history was never simple.

The Civilization That the Forest Hid

The new research focuses on a broad cultural region in what is now Brazil, Bolivia, and Peru. The study’s authors call it the Aquiry cultural area, using an Indigenous name associated with the Acre River. Yet “Aquiry” does not represent the recovered name of a single ancient nation. The people who lived across this territory probably belonged to many linguistic and social groups, and researchers do not know what those communities called themselves.

That distinction matters. For example, headlines about a “lost Amazon civilization” may summon images of a centralized empire, complete with a capital city and a ruling dynasty. In reality, the evidence points toward a multicultural network of communities that shared architectural traditions and elements of a common worldview. They constructed geometric ceremonial centers, maintained roads, farmed the surrounding land, and gathered for political, social, and spiritual events.

According to the peer-reviewed Nature study, Aquiry builders created their characteristic geoglyphs between roughly 600 BCE and 850 CE. Therefore, this way of organizing the landscape endured for about 1,500 years. The culture reached its estimated population peak between 100 and 300 CE, when the Roman Empire dominated much of Europe and the Mediterranean. Meanwhile, an equally remarkable—but very different—form of civilization flourished beneath the tropical sky of South America.

The Aquiry territory covered approximately 183,000 square kilometers, or about 71,000 square miles. It accounted for less than 3 percent of Greater Amazonia, yet researchers believe it may hold as many earthworks as scientists had recently estimated for the entire Amazon basin. That comparison transforms an already impressive discovery into a much larger question: If this one region was so densely organized, what else remains hidden elsewhere?

What LiDAR Saw Beneath the Canopy

LiDAR stands for Light Detection and Ranging. An aircraft sends rapid pulses of laser light toward the ground and measures how long each reflection takes to return. Most pulses strike leaves or branches. Nevertheless, enough light reaches gaps in the vegetation to let researchers build a detailed model of the terrain below.

In other words, LiDAR does not see through solid objects like an X-ray. Instead, it gathers the scattered measurements that reach the forest floor, separates them from reflections off the canopy, and reconstructs the shape of the land. Subtle ditches and embankments that disappear beneath trees can then appear in a digital model with startling clarity.

During 2024, the research team flew 10 survey lines across the Brazilian states of Acre and Amazonas. Altogether, those flights covered 4,430 kilometers and mapped about 4,497 square kilometers. Six of the principal transects ran for roughly 445 kilometers each. They measured strips about one kilometer wide and spaced them approximately 10 kilometers apart, which gave the scientists samples across an enormous landscape.

The scans recorded 432 earthworks, including 396 that researchers had not previously documented. Furthermore, the comparison revealed how much ordinary imagery can miss. In portions of the survey area that scientists had already examined through satellite photographs, earlier work identified only 30 structures. LiDAR found 156 along the same lines—more than five times as many.

Even laser scanning could not reveal everything. Dense vegetation prevented adequate ground measurements in parts of the study area. Consequently, the new map probably still contains blank spaces where additional structures survive. The Amazon continues to hide its past, but LiDAR has given archaeologists a much sharper way to ask where they should look next.

Circles, Squares, Roads, and Monumental Ditches

For example, the structures vary enormously. Many appear as circles, rectangles, squares, or more complicated polygons. Some stand alone, while others form clusters containing as many as eight enclosures. Straight roads extend from several sites, linking ceremonial spaces to water sources or surrounding communities.

These were not shallow lines scratched into the ground. Typical ditches measured about 9 to 13 meters wide and reached as much as 5 meters deep. Most geoglyphs covered between 0.35 and 14 hectares, although the largest known example approaches 50 hectares. At that scale, the biggest complex occupied an area comparable to dozens of football fields.

Because southwestern Amazonia lacks abundant building stone, its inhabitants worked with earth, timber, and vegetation. Wood eventually decayed. Plants reclaimed open spaces. Rain softened exposed features. Still, the excavated ditches and raised embankments endured as fingerprints pressed into the terrain.

Accordingly, researchers interpret many of the geoglyphs as public, political, and ceremonial centers rather than permanently occupied towns or military fortifications. People may have traveled to them for meetings, feasts, rituals, dances, music, athletic contests, and decisions that affected several communities. Therefore, the sites resembled civic gathering places within a dispersed settlement network more than crowded cities of stone.

Furthermore, building them demanded planning. Workers had to choose geometric layouts, clear land, excavate tremendous amounts of soil, form embankments, and maintain the spaces over many generations. Such projects required mathematical knowledge, organized labor, and leadership. Above all, they required enough people to turn an ambitious design into a lasting part of the landscape.

What Ancient Amazon Earthworks Actually Reveal

Importantly, the new study contains two kinds of findings, and separating them helps prevent a fascinating story from becoming an exaggerated one. First, the LiDAR survey produced direct observations. Second, researchers used those observations, earlier archaeological records, radiocarbon dates, satellite surveys, and ethnographic evidence to estimate what may exist beyond the flight lines.

Researchers did not count 30,000 structures one by one. Instead, they calculated densities within sampled zones, divided the larger region into higher- and lower-density areas, and extrapolated from those patterns. One method produced an estimate of 23,760 earthworks. Another approached 29,500. Accordingly, the paper presents a range rather than a deceptively precise total.

Likewise, the same caution applies to population. LiDAR reveals altered ground, not individual people. Archaeologists must estimate how many sites existed simultaneously and how many people each center required. As a result, the population range represents a well-supported proposal, not a census carved into stone.

Still, uncertainty does not make the discovery small. Even the cautious estimate places an extraordinary concentration of monumental architecture in one part of Amazonia. The strongest conclusion remains clear: previous surveys dramatically underestimated the scale of human activity in this forest.

Could Millions of People Really Have Lived There?

To estimate population, the researchers first asked how many Aquiry earthworks might have existed across the high-density core and the less populated edges. Their calculations suggest approximately 16,660 Aquiry-related structures within the broader total of 24,000 to 30,000 earthworks. Next, radiocarbon models indicated that about 25 to 60 percent of those centers may have operated during the peak between 100 and 300 CE.

The team then used an estimate of about 300 people associated with each average center. That figure reflects the workforce needed to build and maintain the earthworks, comparisons with later mound villages, and ethnographic evidence from regional Indigenous gatherings. Multiplying the estimated number of active centers by 300 produced a population range of roughly 1.25 million to 3 million people.

However, not every person would have lived inside a geoglyph. In fact, many of the monumental enclosures show little evidence of permanent occupation. Families likely lived in smaller settlements, farmsteads, and forest communities around the civic centers. Therefore, the earthworks may have functioned as shared destinations within a low-density urban network.

Meanwhile, the study’s authors acknowledge alternative assumptions. If each center represented far fewer residents, the total population would drop substantially. On the other hand, gaps in LiDAR penetration and overlooked structures could push the estimate higher. The paper even notes an adjusted possibility of 1.6 million to 3.8 million people, although its main conclusion retains the more conservative 1.25-million-to-3-million range.

Rather than imagining one continuous metropolis, picture a constellation of communities. Forests, fields, orchards, rivers, homes, roads, and ceremonial plazas filled the spaces between population centers. This settlement pattern spread people across the landscape while connecting them socially and politically.

A Different Kind of Urbanism

Modern readers often judge ancient complexity by stone buildings. The pyramids of Egypt, temples of the Maya, and roads of Rome survived because stone resists time. By contrast, earth and wood can vanish into a living rainforest. Consequently, the Amazon’s architecture left a quieter archaeological signature.

Researchers use terms such as forest urbanism, garden urbanism, or low-density urbanism to describe organized landscapes where homes and civic centers spread across a broad area instead of concentrating behind city walls. Therefore, the Aquiry pattern fits this idea, although archaeologists continue to debate exactly what qualifies as urbanism.

Meanwhile, similar discoveries elsewhere have already weakened the old image of an empty Amazon. In 2022, LiDAR surveys in the Bolivian Amazon revealed large Casarabe sites within a four-tier settlement network. Then, a 2024 study described two millennia of garden urbanism in Ecuador’s Upano Valley. A 2023 analysis also estimated that more than 10,000 pre-Columbian earthworks might remain hidden across Amazonia.

The 2026 Aquiry research adds a startling new scale to that growing picture. One cultural area may contain between 24,000 and 30,000 earthworks by itself. However, the result does not mean that every corner of the Amazon once held dense settlements. The scans found low-density zones and long stretches without detected structures. Some may reflect technical limitations, while others may represent ancient buffer areas with little permanent occupation.

Thus, the best model is neither an empty wilderness nor an unbroken mega-city. Amazonia contained diverse landscapes with different histories. Some regions supported large, organized populations, while others remained lightly inhabited.

How the Aquiry Fed a Vast Population

For years, scholars questioned whether tropical forest soils could support large populations. Heavy rainfall strips nutrients from many Amazonian soils, while dense vegetation stores much of the ecosystem’s fertility above ground. Nevertheless, the Aquiry region includes unusually nutrient-rich soils, and its inhabitants actively managed their environment.

For example, evidence suggests that communities cleared bamboo-rich patches with controlled burning and cultivated maize, squash, and manioc. They probably grew sweet potatoes, chili peppers, beans, and peanuts as well. Moreover, archaeological excavations have uncovered remains of Brazil nuts and several palms, including peach palm and bacaba.

Moreover, these plants tell a deeper story. A forest can look wild while preserving centuries of human choices. Families protected useful trees, planted favored species, encouraged productive groves, and changed which plants dominated particular areas. As generations repeated those decisions, human preferences became part of the forest’s ecology.

The connection remains visible today. Researchers have found valuable trees clustered near archaeological sites, and the western distribution of Brazil nut trees in the area roughly corresponds with the boundary of geometric earthworks. Therefore, the modern rainforest may function partly as a living artifact of precolonial land management.

However, this evidence does not mean that ancient people controlled the entire forest or always used it sustainably. Nor does it erase the Amazon’s immense natural history. Instead, nature and culture shaped one another. A biodiverse forest can be ancient, ecologically complex, and profoundly influenced by human communities at the same time.

Ceremonies, Roads, and a Shared World

However, the earthworks reveal more than organization because their meaning went beyond engineering. According to the University of Helsinki’s account of the study, Indigenous oral traditions describe ceremonial centers as places that supported relationships among communities and with other significant beings. Gatherings could include feasting, dance, music, ball games, athletic competition, political decisions, and displays of generosity by leaders.

Roads played an important role in that landscape. Instead of merely moving goods from one location to another, routes may have guided ceremonial processions and linked communities to water, cultivated spaces, and sacred places. Straight alignments also reveal how carefully people planned the region.

Modern Apurinã knowledge offers valuable context. The study notes that Apurinã communities have held gatherings involving roughly 200 to 400 people and created open ceremonial spaces and roads for different stages of an event. Their collaborators also retain knowledge about the past use of earthworks. Such evidence does not provide a simple one-to-one explanation for every ancient site, but it helps archaeologists understand how large gathering spaces can serve dispersed populations.

Crucially, this history does not belong only to a vanished people. Indigenous nations still live in Amazonia, maintain cultural knowledge, and protect landscapes connected to their ancestors. Future research must respect their rights, leadership, and decisions about sensitive sites. Archaeological discovery should never become an invitation for treasure hunting or unauthorized tourism.

Why Did the Aquiry System Fade?

Eventually, the characteristic Aquiry geoglyph tradition appears to have declined around 850 CE. Yet researchers do not know why. Environmental change, political transformation, conflict, migration, shifting trade networks, or new forms of settlement could all have played roles. At present, the evidence does not support one confident answer.

Moreover, a change in architecture does not necessarily mean that the population vanished. Later communities built round or rectangular mound villages in parts of the same region, especially after about 1000 to 1200 CE. They used related agricultural strategies and lived near earlier ceremonial centers. Consequently, the end of the geoglyph-building tradition may reflect social reorganization rather than total collapse.

That difference matters because the word “collapse” creates a dramatic but sometimes misleading picture. Societies rarely disappear in a single moment. People move, merge, adapt, change languages, adopt new customs, and reorganize their settlements. The monumental centers may have lost their earlier roles while local communities continued to transform the landscape.

European colonization came centuries later and brought catastrophic violence, enslavement, displacement, and disease across the Americas. Those events devastated Indigenous populations and erased or distorted vast amounts of historical knowledge. However, they cannot directly explain why this particular architectural tradition faded around 850 CE. The mystery began long before Europeans reached the region.

For now, the rainforest preserves the question. Each newly mapped road, enclosure, habitation site, charcoal layer, plant remain, and pottery fragment may help researchers reconstruct what changed.

The Myth of an “Untouched” Amazon

The idea of a pristine, people-free rainforest has shaped public imagination for a long time. Yet it creates a false choice between nature and human history. If people modified a landscape, some assume it cannot remain natural. Conversely, if a forest appears lush and biodiverse, they assume humans never shaped it.

The Aquiry evidence breaks that simple division. People cleared selected areas, burned vegetation, cultivated food, built roads, dug ditches, gathered by the hundreds, and encouraged useful trees. Then the forest grew over many of their structures. Human action and ecological recovery became layered together.

This discovery also changes how scientists interpret biodiversity, soil, and carbon. If sizable populations managed forests for centuries, their actions may have influenced which trees dominate today, where fertile soils occur, and how carbon moved through the ecosystem. The Nature study therefore argues that researchers should consider this legacy in future climate models and sustainable land-use planning.

However, the findings do not justify modern deforestation. Ancient communities transformed selected landscapes without industrial machinery, global commodity markets, or today’s pace of clear-cutting. Their long relationship with the forest differs fundamentally from rapidly converting enormous areas into pasture, mines, roads, or monoculture.

Instead, the research strengthens the case for protecting both ecology and cultural heritage. Every cleared area can destroy habitats while also erasing earthworks, artifacts, soils, and plant patterns that preserve human history. Conservation in Amazonia protects more than trees; it also safeguards one of the world’s largest archaeological landscapes.

What Scientists Still Need to Discover

LiDAR provides a map, but it cannot answer every archaeological question. Researchers must visit a sample of the detected sites, study their soil and artifacts, and confirm whether apparent structures have human origins. Excavations can reveal pottery, food remains, postholes, charcoal, construction phases, and signs of occupation. Meanwhile, radiocarbon dating can establish when people built, used, altered, or abandoned each location.

Likewise, future surveys need broader coverage. The new flight lines sampled a vast region, but they did not scan every square kilometer. More LiDAR could test whether the current density estimates hold between transects. Additionally, work in Rondônia may clarify the southeastern boundary of the Aquiry area.

Archaeologists must also find the everyday settlements associated with ceremonial centers. Where did families sleep, cook, farm, and raise children? How often did they visit the geoglyphs? Did neighboring communities share one center, or did each maintain its own? Answers to those questions will strengthen or revise the population estimates.

Finally, collaboration with Indigenous communities remains essential. Oral histories, place knowledge, ecological expertise, and cultural interpretations can reveal relationships that remote sensing alone cannot detect. Researchers should treat those communities as partners and knowledge holders, not simply as people living near archaeological sites.

The most exciting part of this discovery may be how much uncertainty remains. Scientists now possess a far larger map, but every new shape creates another question about the people who designed it.

The Amazon Is Also a Human Archive

The newly revealed landscape does not resemble El Dorado, and archaeologists have not uncovered a single golden capital beneath the trees. The truth is richer. Across southwestern Amazonia, generations of people created a network of geometric centers, roads, farms, orchards, and gathering places that endured for roughly 1,500 years.

These ancient Amazon earthworks force us to reconsider what a city can look like, what architecture can survive, and how thoroughly a forest can conceal the past. More importantly, they remind us that absence on a map does not equal absence in history. Sometimes, the evidence has been there all along, hidden beneath leaves and visible only when technology—and human curiosity—learns how to look.

Frequently Asked Questions

Did scientists discover a lost city beneath the Amazon?

Not exactly. LiDAR documented hundreds of geometric earthworks, roads, ditches, and embankments across southwestern Amazonia. The evidence points to a broad network of communities and ceremonial centers rather than one newly discovered city or centralized empire.

How many Amazon earthworks did the researchers find?

The 2024 LiDAR survey directly documented 432 earthworks, including 396 that were previously unknown. By combining those results with earlier satellite surveys and archaeological evidence, the researchers estimated that approximately 24,000 to 30,000 earthworks may exist across the full study region.

Who built the Amazon geoglyphs?

Researchers use the name Aquiry for the multicultural network associated with many geometric earthworks in the region. However, the communities probably spoke different languages, and no one knows what they called themselves. Aquiry comes from an Indigenous name connected to the Acre River.

How many people lived in the Aquiry cultural area?

The Nature study estimates that approximately 1.25 million to 3 million people lived across the region at its peak between 100 and 300 CE. That range relies on models of site numbers, simultaneous use, labor needs, archaeology, and ethnographic comparisons, so researchers may revise it as more sites receive field investigation.

Why are the earthworks so difficult to see?

Dense vegetation hides low ditches and embankments from ordinary aerial photographs and satellite imagery. LiDAR collects laser reflections that reach the forest floor and uses them to create a digital terrain model, allowing subtle human-made shapes to appear beneath the canopy.

Does this prove that the entire Amazon was once densely populated?

No. The study covers southwestern Amazonia and found both high-density and low-density areas. It shows that some regions supported large, organized populations, but researchers need comparable surveys elsewhere before applying the same conclusions to the entire Amazon basin.

The post Ancient Amazon Earthworks: The Vast Civilization Hidden Beneath the Rainforest appeared first on The Chronicle of Curiosity.

With its flat body panels, exposed hinges, removable doors and folding windshield, the Thing looks less like a conventional automobile than a tool shed that learned to drive. It is neither elegant nor fast. Moreover, it does not pretend to be. The little Volkswagen has the square-jawed honesty of a metal lunchbox, the mechanical simplicity of a lawn mower and the cheerful spirit of a beach buggy.

That combination made it one of the coolest and oddest production vehicles of the twentieth century. However, its story did not begin under a palm tree. It began with soldiers, government requirements and a supposedly temporary solution that refused to disappear.

Before the Thing: The Volkswagen Kübelwagen

The Thing’s family tree reaches back to the Volkswagen Type 82 Kübelwagen of World War II. Ferdinand Porsche and his engineering team developed that military vehicle from the same basic rear-engine ideas behind the early Volkswagen Beetle. German forces used the Kübelwagen as a light personnel carrier, scout car and general-purpose runabout.

Its German nickname roughly meant “bucket-seat car,” although English speakers often translate it more loosely as “bucket car.” Despite lacking four-wheel drive, the Kübelwagen performed surprisingly well away from pavement. Low weight, a flat underside, high ground clearance and rear-biased weight over the driven wheels helped it cross terrain that could trap heavier machines.

Still, the later Type 181 was not simply a wartime Kübelwagen dragged back into production. The two vehicles shared a philosophy more than a set of body panels. Both used proven Volkswagen mechanical parts beneath a simple, lightweight utility body. In other words, Volkswagen did not reinvent the wheel. It checked the warehouse to see which wheels were already paid for.

That distinction matters. Calling the Thing a reborn Kübelwagen makes for a tidy story, but the reality is more interesting. The Type 181 combined lessons from Volkswagen’s past with parts and ideas developed long after the war.

A Cold War Problem in Need of a Quick Answer

By the 1960s, the West German military needed a successor to the aging DKW Munga, a compact four-wheel-drive vehicle powered by a two-stroke engine. Meanwhile, West Germany, France and Italy were participating in an ambitious program to create a shared military utility vehicle commonly known as the Europa Jeep.

The proposed machine was expected to do nearly everything. It would be light, amphibious, four-wheel drive, durable and suitable for several national armies. Unfortunately, designing a vehicle by international committee proved about as quick and painless as teaching a tank to dance.

Development dragged on, but the Bundeswehr still needed an affordable light transport. Therefore, the West German government turned to Volkswagen for a practical interim vehicle. According to a 1973 submission from Volkswagen of America to the National Highway Traffic Safety Administration, the Model 181 had originally been designed under contract for the German government, with rough-terrain operation shaping its basic concept.

Volkswagen began regular production in 1969. The resulting Type 181 looked military because it was military. Its slab-sided body, nearly flat hood, detachable doors, basic interior and folding windshield all served practical purposes. Fancy trim would have added cost, and chrome does little to improve a field radio delivery.

The supposed stopgap eventually outlived the Europa Jeep program it had been created to bridge. Military organizations valued the Type 181 because it was dependable, inexpensive and easy to maintain. Sometimes the temporary answer becomes permanent simply because it starts every morning.

Who Designed the Volkswagen Thing?

No single famous stylist receives reliable credit for designing the Type 181. Unlike a sports car shaped around one designer’s dramatic vision, the Thing emerged from an in-house Volkswagen engineering effort guided by a government contract and a military job description.

Ferdinand Porsche often enters discussions about the vehicle because he designed the Beetle and helped create the wartime Kübelwagen. However, Porsche died in 1951, long before Type 181 production began. He influenced the mechanical family tree, but he did not personally design the Thing.

Another important branch of that tree grew in Australia. Volkswagen Australasia developed the Country Buggy during the 1960s as a rugged vehicle for rural and military use. It also featured a simple open body over familiar Volkswagen hardware. The Australian machine and the Type 181 were separate projects, yet the Country Buggy helped demonstrate how existing VW components could support a bare-bones utility vehicle.

Ultimately, the Thing looks anonymous because function dictated its appearance. Every flat panel seems ready for a hammer, every hinge announces itself and every opening appears sized for someone wearing muddy boots. A designer seeking beauty might have hidden those details. Volkswagen’s engineers practically put arrows beside them.

Building a Utility Vehicle from the Volkswagen Parts Bin

The Type 181 was clever rather than revolutionary. Volkswagen used a strengthened platform related to the Karmann Ghia, a Beetle-derived engine, familiar steering and suspension components, and gearing selected for useful low-speed performance. This approach lowered costs while allowing mechanics familiar with air-cooled Volkswagens to understand much of the machine.

American-market Things used a 1.6-liter air-cooled flat-four engine and a four-speed manual transmission. Horsepower was modest—roughly in the mid-40s, depending on model year and measurement—but speed was never the mission. The vehicle weighed about 2,000 pounds, and its low gearing helped it scramble over poor roads.

Notably, the Thing had rear-wheel drive rather than four-wheel drive. That sounds almost scandalous for a military-style off-roader. Nevertheless, Volkswagen argued that the vehicle’s low weight, rearward weight bias and four-wheel independent suspension made four-wheel drive unnecessary for its intended duties.

In its 1973 case to NHTSA, Volkswagen listed 8.1 inches of ground clearance, a 36-degree approach angle, a 31-degree departure angle and a fording depth of 15.6 inches. The company also noted protective shields, heavy-duty tires, towing eyes and reinforced suspension mounting points. Consequently, the Thing could venture far beyond places where an ordinary Beetle wisely stopped to reconsider its life choices.

Doors Optional, Personality Standard

The body supplied many of the features that make the Thing so memorable. All four doors could be removed without turning the process into a weekend restoration project. The windshield folded forward, while the soft top and flexible side curtains provided weather protection in the loosest possible sense of the word “protection.”

Inside, washable-looking surfaces, simple seats and minimal decoration reinforced the utility-car character. The rear seat folded to create additional cargo room. Moreover, the tall, upright body made the cabin feel airy when the weather cooperated.

Of course, comfort depended heavily on expectations. The air-cooled engine added its familiar mechanical soundtrack, wind found every available opening and the soft top treated heavy rain as a suggestion. Heating came from the same general school of optimism found in other classic air-cooled Volkswagens.

Still, those shortcomings became part of the charm. The Thing turned an ordinary drive into an event. Remove the doors, fold the windshield and head toward a trail or beach, and suddenly 46 horsepower feels less like a limitation and more like a comedy partner.

From Kurierwagen to Safari to “The Thing”

Volkswagen sold the Type 181 under different names around the world. German buyers knew it as the Kurierwagen, or “courier car.” In Mexico it became the Safari, while British customers received the right-hand-drive Type 182 as the Trekker. Italy used the name Pescaccia, and other regional labels appeared as well.

For the United States, Volkswagen wanted to use Safari. However, Pontiac had already used that name on station wagons. Volkswagen of America therefore chose “The Thing,” which may be the greatest accidental piece of automotive marketing ever devised.

The name created instant curiosity. Ask someone whether they drive a Safari, and they might picture a rugged vehicle. Tell them you drive a Thing, and they have to ask a second question. That is free advertising.

Volkswagen introduced the Mexican-built Thing to American buyers for the 1973 model year and sold it again for 1974. Bright colors softened its military appearance, while advertising emphasized outdoor fun. In America, the vehicle stopped looking like a courier car for soldiers and started looking like the official transport of anyone who owned a surfboard, a tent or an unusually relaxed attitude toward side-impact protection.

Who Bought This Strange Little Car?

The American Thing arrived at exactly the right cultural moment. Dune buggies, recreational vehicles and imported economy cars had already captured the public’s imagination. The Beetle had made Volkswagen familiar, while the Microbus had become a rolling emblem of travel, youth culture and doing things differently.

Consequently, the Thing appealed to outdoorsmen, campers, beachgoers, surfers and drivers who wanted something unlike the sedans parked next door. Rural owners could appreciate its ground clearance and mechanical simplicity. Volkswagen enthusiasts recognized its familiar air-cooled components. Meanwhile, individualists bought it for the same reason people later bought unusual vehicles such as the Plymouth Prowler or Nissan Cube: sensible transportation was available, but sensible transportation was not the point.

The car also found buyers who liked military styling without needing a full-size four-wheel-drive truck. Its removable body pieces made it feel playful, while four doors gave it a degree of practicality missing from many open utility vehicles.

Admittedly, it was not inexpensive enough to be an impulse purchase for everyone. Nor was it polished enough to challenge a conventional family car. The ideal Thing buyer saw rattles as conversation starters, slow acceleration as scenery appreciation and a removable roof as an excellent reason to ignore the forecast.

The Thing Versus Its Rivals

The Type 181 occupied a peculiar space between economy car, military runabout, off-roader and recreational toy. Therefore, no rival matched it perfectly. Several vehicles, however, chased a similar promise of simple open-air adventure.

Volkswagen itself named Jeeps, Land Rovers and Broncos when arguing to NHTSA that the Type 181 qualified as a multipurpose passenger vehicle. The company even pointed out that some competing utility vehicles could be purchased with two-wheel drive.

Nevertheless, a Jeep CJ was the better choice for hard trails, and a Land Rover could perform heavier work. The Thing’s real advantage was its mixture of simplicity, low weight, familiar VW mechanics and sheer friendliness. A Jeep looked ready to conquer a mountain. A Thing looked ready to ask whether the mountain had a nice picnic area.

Why Did American Sales End So Quickly?

The Thing’s American career lasted only two model years, which greatly contributed to its later mystique. Its disappearance is often reduced to the broad statement that it “could not meet new safety standards.” That is directionally correct, although the regulatory story deserves care.

In April 1973, NHTSA accepted Volkswagen’s classification of the Model 181 as a multipurpose passenger vehicle. Volkswagen supported that classification by documenting the Thing’s rough-terrain features and comparing it with Jeeps, Land Rovers, Broncos, Scouts and other utility vehicles.

Later regulatory changes and passenger-vehicle safety requirements made continued American certification impractical for such a basic design. The windshield position and occupant-protection rules often receive particular attention in accounts of its withdrawal. Rather than substantially redesign a low-volume specialty vehicle, Volkswagen removed the Thing from its American lineup after 1974.

The decision made business sense. Still, it denied Americans the chance to become tired of the car. Instead, the Thing vanished while it was still strange, colorful and memorable—the automotive equivalent of a television show canceled before it had time to produce a bad final season.

Production for other markets continued. Civilian manufacturing lasted into 1980, while military orders carried the broader Type 181 story into the early 1980s. Across its various factories and versions, roughly 90,000 examples were produced.

Fun Stories, Odd Details and Thing Trivia

It Was a Temporary Vehicle That Won the Waiting Game

The Type 181 existed partly because the Europa Jeep was taking too long. Yet the grand multinational project eventually collapsed, while Volkswagen’s temporary substitute served for years. Somewhere in the great filing cabinet of history, that deserves a note reading, “Good enough beat perfect again.”

It Was Not a 4×4—and Volkswagen Was Proud of That

Rather than apologize for rear-wheel drive, Volkswagen defended it. The company argued that light weight, independent suspension and engine weight over the rear wheels produced genuine rough-road ability. In certain conditions, a light vehicle can float over loose ground where a heavier four-wheel-drive machine digs in.

Every Market Seemed to Name It Differently

Kurierwagen sounded official. Safari sounded adventurous. Trekker sounded outdoorsy. Pescaccia sounded distinctly Italian. “The Thing,” however, sounded like a B-movie creature parked in the driveway. Naturally, that was the name Americans remembered.

It Shares a Spirit with the Dune Buggy

The Thing was a factory-built vehicle rather than a fiberglass kit car. Even so, both embraced light weight, air-cooled VW power and open-air recreation. Owners also modified Things with larger tires, custom tops, bright paint and accessories, making two identical examples increasingly difficult to find.

The Doors Can Come Off Before the Conversation Ends

On many cars, removing a door suggests a collision or an alarming repair bill. On the Thing, it suggests the weather has improved. That single feature explains much of the vehicle’s personality.

What Is It Like to Drive?

Driving a Thing requires recalibrating modern expectations. Acceleration is leisurely, the steering feels light and mechanical, and the flat-four engine makes its presence known. Highway travel is possible, although relaxed secondary roads suit the vehicle better than fast interstate traffic.

Visibility is excellent because the body is upright and the hood slopes away. Meanwhile, the compact dimensions make the Thing easy to place on a narrow road or trail. The suspension and ground clearance encourage exploration, but rear-wheel drive and limited power establish sensible boundaries.

Most importantly, the experience feels direct. Modern cars work hard to isolate occupants from heat, noise, wind and vibration. The Thing gathers all four, introduces them personally and invites them along for the ride.

Safety also demands honest consideration. The design predates airbags, modern crash structures, electronic stability control and contemporary side-impact protection. Therefore, anyone driving a surviving example should respect its limitations, maintain its brakes and tires carefully, and treat defensive driving as essential equipment.

Why Collectors Still Love the Volkswagen Thing

Today, surviving Things attract Volkswagen enthusiasts, collectors of unusual vehicles and people who simply want a classic that makes strangers smile. Parts-bin engineering can simplify portions of ownership because many mechanical components connect to the wider air-cooled Volkswagen world. Conversely, Thing-specific body panels, doors, trim and accessories can be harder and more expensive to locate.

Rust deserves close attention. Floors, rocker areas, body seams, suspension mounting points and other structural sections can suffer, particularly on vehicles that spent years near saltwater or on winter roads. A charming paint job should never distract a buyer from a careful inspection underneath.

Originality also varies widely. Owners treated these cars as toys and utility vehicles rather than future museum pieces, so modifications are common. Some changes improve usability, while others erase hard-to-replace original parts. Buyers should decide whether they want a factory-correct collectible or a cheerful driver they can enjoy without fearing every pebble.

The Thing’s short American sales period adds desirability, but rarity alone does not explain its following. Plenty of uncommon cars remain obscure. The Type 181 endures because its shape, name and purpose can be understood in seconds. It is honest, approachable and impossible to confuse with anything else.

A Vehicle Too Strange to Forget

The full Volkswagen Thing history reveals a machine built from contradiction. It was a military vehicle that became a beach car, a rough-terrain machine without four-wheel drive and a temporary solution that lasted far longer than expected. Furthermore, its styling was almost aggressively practical, yet that lack of styling became its most recognizable feature.

Volkswagen did not need a glamorous designer or a powerful engine to make the Type 181 memorable. Instead, the company combined proven components, a useful body and a remarkable absence of pretension. The result could carry soldiers, camping gear, surfboards or four people who did not mind arriving with windblown hair.

That may be the secret behind its lasting appeal. Many classic cars ask us to admire them from a respectful distance. The Thing looks as though it wants us to remove the doors, throw a cooler in the back and see where that dirt road goes.

Would I call it beautiful? Not in the traditional sense. Still, if personality counts as beauty, the Thing is a supermodel wearing combat boots.

Frequently Asked Questions About the Volkswagen Thing

What was the Volkswagen Thing’s official model number?

Volkswagen designated the left-hand-drive vehicle as the Type 181. Right-hand-drive examples were known as the Type 182.

Was the Volkswagen Thing made for the military?

Yes. Volkswagen developed it under contract for the West German government as an inexpensive light utility vehicle. Civilian versions followed after military production was underway, creating the unlikely second act that makes Volkswagen Thing history so fascinating.

Did Ferdinand Porsche design the Volkswagen Thing?

No. Porsche influenced its ancestry through the Beetle and wartime Kübelwagen, but he died years before the Type 181 entered production. Volkswagen’s internal engineering program developed the later vehicle.

Is the Volkswagen Thing four-wheel drive?

No. Standard Type 181 vehicles use rear-wheel drive. Low weight, rear-engine traction, independent suspension, good clearance and low gearing still gave the vehicle useful rough-terrain ability.

Why is it called “The Thing”?

Volkswagen used names including Kurierwagen, Safari and Trekker in other markets. Because Pontiac had used the Safari name in the United States, Volkswagen of America selected the deliberately unusual name “The Thing.”

How fast was a Volkswagen Thing?

Performance varied by model and condition, but speed was modest. A stock American-market Thing is happiest at relaxed classic-car speeds rather than trying to dominate a modern freeway.

Why did Volkswagen stop selling it in the United States?

Newer American safety requirements made continued certification impractical without redesigning the basic vehicle. Volkswagen ended regular U.S. sales after the 1974 model year.

How many Volkswagen Things were built?

Commonly cited production records place combined Type 181 output at roughly 90,000 vehicles across German and Mexican production, with additional assembly associated with other markets.

Some books sell a few copies. Some books sell a few million. Then there are the literary giants that stomp through publishing history like Godzilla in a library card catalog. The best-selling books of all time are not just books. They are cultural earthquakes, classroom assignments, spiritual guides, movie franchises, collector obsessions, and in some cases, doorstops with surprisingly good marketing.

But there is one problem.

Counting the best-selling books in history is not as simple as checking a receipt. Older books were printed by countless publishers. Religious texts were sold, distributed, gifted, translated, copied, and sometimes handed out by the truckload. Public-domain classics have been republished so many times that tracking every copy is like trying to count popcorn kernels after the movie starts.

So, rather than pretending this is an exact science, let’s treat it for what it is: a fascinating tour through the books that conquered shelves around the world.

And yes, we will ask the most important question at the end: how many of these have you actually read?

Why Best-Selling Book Lists Get Messy

Before we crown the champions, we need a quick warning label.

Book sales are slippery.

A modern bestseller might have detailed publisher records, audiobook numbers, e-book data, and enough sales tracking to make a spreadsheet blush. Older books? Not so much. A book like Don Quixote has been around since the early 1600s. The Bible has circulated for centuries in countless editions and translations. Shakespeare’s works have been printed, reprinted, adapted, abridged, bundled, quoted, and assigned to students who definitely waited until the night before to read Act III.

Then there are series. Do we count Harry Potter as one category winner because the series sold more than 600 million copies? Or do we compare only single books? Is The Lord of the Rings one book or three? Is The Little Prince a children’s book, a philosophical fable, or a tiny emotional ambush disguised as a bedtime story?

The answer is: yes.

That is why the following list focuses on broad literary categories and the titles most commonly recognized as the leaders in those lanes.

All Books: The Bible

At the top of the mountain sits the Bible, widely recognized as the best-selling book of all time. Estimates often place its total circulation in the billions, usually somewhere around five to seven billion copies sold and distributed.

That number is almost impossible to prove with absolute precision, but the Bible’s influence is beyond debate. It has shaped religion, politics, art, literature, language, law, music, and more church potlucks than anyone can count.

Whether sitting on a pulpit, a hotel nightstand, a family shelf, or an app on a smartphone, the Bible remains the heavyweight champion of publishing history.

It is not just a bestseller. It is the bestseller.

Best-Selling Novel Overall: Don Quixote

For the best-selling novel of all time, the crown usually goes to Don Quixote by Miguel de Cervantes.

First published in two parts in 1605 and 1615, Don Quixote follows an aging gentleman who reads so many chivalric romances that he decides to become a knight himself. This would be admirable, except his enemies include windmills, his armor is questionable, and his grip on reality is, shall we say, lightly buttered.

But beneath the comedy is one of the most important works in Western literature. Don Quixote helped shape the modern novel. It plays with fantasy and reality, heroism and delusion, idealism and embarrassment. In other words, it is both a literary masterpiece and possibly the first great story about a man who badly needed someone to say, “Maybe take a nap before making this decision.”

Its estimated sales are often placed around 500 million copies, making it the usual answer for the best-selling novel ever written.

Political and Ideological Books: Quotations from Chairman Mao Tse-tung

In the category of political and ideological books, the giant is Quotations from Chairman Mao Tse-tung, better known as The Little Red Book.

This compact collection of Mao Zedong’s sayings was massively printed and distributed during China’s Cultural Revolution. Estimates vary wildly, and the numbers are complicated because many copies were state-produced or distributed rather than sold through normal commercial channels.

Still, the scale was enormous. It became one of the most widely printed books in history.

This is a good reminder that “best-selling” and “most distributed” are not always the same thing. A book can become globally famous because readers choose it, because schools assign it, because governments promote it, or because it gets turned into a film starring Tom Hanks sprinting through European landmarks. Publishing history contains multitudes.

Fantasy: The Lord of the Rings

For fantasy, the single-work champion is usually The Lord of the Rings by J. R. R. Tolkien.

Yes, this gets tricky. Tolkien’s masterpiece is often sold as three volumes: The Fellowship of the Ring, The Two Towers, and The Return of the King. But Tolkien conceived it as one grand work, and many editions publish it that way.

Either way, it is a titan.

With more than 150 million copies sold worldwide, The Lord of the Rings did more than sell books. It helped define modern fantasy. Elves, dwarves, dark lords, magical rings, ancient prophecies, epic maps, and suspiciously long walks across dangerous terrain all owe something to Tolkien’s world.

Without Tolkien, the fantasy aisle would look very different. Possibly shorter. Definitely with fewer apostrophes.

Fantasy Series: Harry Potter

If we switch from single works to series, Harry Potter takes the broomstick and flies away with the trophy.

J. K. Rowling’s seven-book series has sold more than 600 million copies worldwide. It became the best-selling book series of all time, launched one of the biggest film franchises ever, and caused an entire generation to wait beside mailboxes hoping an owl had simply been delayed.

The series blended school story, fantasy adventure, mystery, coming-of-age drama, and enough magical bureaucracy to make even a wizard file paperwork.

Love it, debate it, reread it, or argue about which house you belong to, Harry Potter is one of the clearest examples of a publishing phenomenon becoming a global cultural language.

Children’s Literature and Fable: The Little Prince

Few books are as small, strange, and emotionally sneaky as The Little Prince by Antoine de Saint-Exupéry.

On the surface, it is a children’s story about a young prince traveling from planet to planet. Underneath, it is a meditation on loneliness, love, imagination, friendship, adulthood, and why grown-ups are often very weird.

The book has sold around 200 million copies worldwide and has been translated into hundreds of languages. That makes it one of the most successful books in publishing history.

It is also one of those books people describe as “simple,” right before quietly staring out a window for twenty minutes.

Science Fiction: Dune

For classic science fiction, the leading title is usually Dune by Frank Herbert.

Set on the desert planet Arrakis, Dune gives readers politics, religion, ecology, prophecy, giant sandworms, dynastic warfare, and the most stressful spice trade in literature. It is science fiction, but it is also a power struggle, a survival epic, and a warning that mixing politics with messianic destiny usually ends with everyone needing a glass of water.

Dune has sold around 20 million copies and is often cited as the best-selling science fiction novel of all time.

It is also proof that a book can be deeply philosophical and still make readers say, “Tell me more about the enormous worm.”

Mystery and Crime: And Then There Were None

In mystery and crime fiction, the crown belongs to Agatha Christie’s And Then There Were None.

The setup is deliciously sinister: ten strangers are invited to a remote island. Then they begin dying one by one. There is no detective conveniently standing in the drawing room. No comforting pipe smoke. No “Ah-ha!” from Hercule Poirot. Just paranoia, guilt, murder, and the dawning realization that this vacation package received poor reviews for a reason.

With more than 100 million copies sold, And Then There Were None is often called the best-selling mystery or crime novel of all time.

Agatha Christie did not just dominate the genre. She built a mansion in it, locked all the doors, and hid the key under a corpse.

Thriller: The Da Vinci Code

For modern thrillers, The Da Vinci Code by Dan Brown is one of the biggest commercial hits ever.

Published in 2003, the book threw together secret societies, religious history, puzzles, symbols, murder, museums, and enough cliffhangers to make readers keep saying, “Just one more chapter,” until suddenly it was 2:00 a.m. and they had opinions about the Holy Grail.

The book sold tens of millions of copies worldwide, often cited around 80 million or more, and became a global phenomenon.

Literary critics argued. Historians sighed. Readers bought it by the truckload.

That, in publishing terms, is called “winning the argument at the cash register.”

Dystopian Fiction: 1984

In dystopian fiction, George Orwell’s 1984 remains one of the most important and widely read books ever written.

Published in 1949, 1984 gave the world Big Brother, Newspeak, doublethink, Room 101, and a bleak vision of surveillance and authoritarian control. It is one of those novels people reference constantly, sometimes accurately, sometimes because they had a frustrating experience with a parking meter.

The book has sold around 30 million copies and remains painfully relevant in conversations about power, truth, language, technology, and political manipulation.

Not bad for a book that basically says, “What if the future was terrible and also had paperwork?”

Young Adult Dystopian Fiction: The Hunger Games

For young adult dystopian fiction, The Hunger Games by Suzanne Collins is the modern arena champion.

The series has sold more than 100 million copies worldwide. It combines survival drama, political rebellion, media spectacle, class conflict, and the unforgettable image of teenagers forced into televised combat by a corrupt government.

Cheery stuff for young readers, right?

But that is part of its power. The Hunger Games took a brutal premise and used it to explore propaganda, inequality, trauma, celebrity, and resistance. It also gave the world Katniss Everdeen, one of the most recognizable heroines in modern fiction.

The odds, commercially speaking, were very much in its favor.

Romance and Erotic Romance: Fifty Shades of Grey

In modern romance and erotic romance, Fifty Shades of Grey by E. L. James became one of the biggest publishing sensations of the 21st century.

The trilogy sold more than 150 million copies worldwide, sparked endless debates, inspired films, and made the phrase “inner goddess” much harder to hear with a straight face.

Whether praised as a guilty pleasure, criticized for its prose and relationship dynamics, or studied as a publishing phenomenon, Fifty Shades proved something important: readers will absolutely turn out for a book that everyone is whispering about.

Sometimes curiosity sells. Sometimes controversy sells. Sometimes both show up wearing expensive gray suits.

Memoir and Diary: The Diary of a Young Girl

Some bestselling books become famous because they entertain. Others endure because they bear witness.

The Diary of a Young Girl by Anne Frank is one of the most important personal documents of the 20th century. Written while Anne and her family hid from the Nazis in Amsterdam, the diary gives readers an intimate view of fear, hope, adolescence, confinement, and humanity under unimaginable pressure.

It has sold more than 30 million copies and has been translated into more than 70 languages.

Its power is not in spectacle. It is in voice. Anne Frank’s writing reminds readers that history is not just dates, armies, and governments. It is also a young girl thinking, dreaming, worrying, arguing, observing, and hoping in the middle of catastrophe.

Cookbook: Better Homes and Gardens New Cook Book

Not every bestseller involves murder, prophecy, magical rings, or authoritarian nightmares. Some involve casseroles.

The Better Homes and Gardens New Cook Book, often called the “Red Plaid Cookbook,” is one of the best-selling cookbooks in American history. First published in 1930, it has sold tens of millions of copies and became a kitchen staple for generations.

It taught people how to cook, bake, plan meals, and rescue dinner from whatever was hiding in the pantry. For many families, it was less of a cookbook and more of a domestic survival manual.

A fantasy novel may teach you how to defeat a dark lord, but a good cookbook teaches you how not to ruin Thanksgiving. Both are heroic quests.

Drama and Plays: William Shakespeare

For drama, we cannot really crown one single play with confidence. Instead, the throne belongs to William Shakespeare as a body of work.

Shakespeare is widely recognized as the best-selling playwright in history, with billions of copies of his plays and poetry believed to have circulated over the centuries.

His influence is everywhere. Hamlet, Macbeth, Romeo and Juliet, Othello, King Lear, A Midsummer Night’s Dream—these works have shaped language, theater, storytelling, and high school essay anxiety for generations.

Shakespeare also gave us insults with real style. Modern people say, “You’re annoying.” Shakespeare might say something like, “Thou art as tedious as a twice-told tale.” Honestly, the man had range.

The Quick Shelf: Category Winners at a Glance

Here is the rapid-fire version for anyone who loves a good list:

What These Books Have in Common

At first glance, this list looks chaotic.

A Spanish knight attacks windmills. A boy wizard goes to school. A little prince visits planets. A desert messiah rides sandworms. Ten people make the mistake of accepting an island invitation. A cookbook tells you what to do with ground beef. Shakespeare makes everyone fall in love, die, or both.

Yet these books all share something important: they entered the public imagination.

Some did it through faith. Some through story. Some through suspense. Some through schools. Some through controversy. Some through sheer usefulness. A few did it by becoming so famous that people pretend they have read them at dinner parties.

No judgment. We have all nodded thoughtfully at the mention of a classic while silently thinking, “I saw the movie.”

Which Ones Have You Read?

Now comes the fun part.

How many of these best-selling books have you actually read?

Have you tackled Don Quixote or only heard about the windmills? Have you read Dune, or do you just know that spice is important and sandworms are a problem? Did And Then There Were None keep you guessing? Did 1984 make you suspicious of your smart devices? Did the Better Homes and Gardens New Cook Book save dinner at your house?

And be honest: did Shakespeare make more sense on the page, on the stage, or when someone finally explained it after the test?

The best-selling books of all time are more than sales records. They are proof that stories, ideas, recipes, warnings, mysteries, and dreams can travel farther than anyone expects.

Some books become famous.

Some books become history.

And some books become the reason your bookshelf is sagging in the middle.

Few locations in Top Gun: Maverick captured audiences quite like The Hard Deck. Nestled beside the ocean and filled with fighter pilots, rivalries, laughter, and tradition, the bar felt as authentic as the aircraft roaring overhead. Yet many viewers left the theater wondering whether The Hard Deck was a real place. While the famous bar itself was created for the film, the culture behind it is deeply rooted in military aviation history. To understand why The Hard Deck resonates with audiences, we need to explore the fascinating world of aviator bars and the role they play in the lives of military pilots.

These bars are more than places to grab a drink. They serve as community centers, informal classrooms, networking hubs, and living museums of aviation history. Although Hollywood often adds glamour and romance to these locations, the real-world purpose of aviator bars runs much deeper.

To understand why these establishments matter so much, we first need to explore the unique world of military aviation.

What Is an Aviator Bar?

An aviator bar is traditionally a gathering place frequented by military pilots, flight crews, and aviation personnel. Many are located near military air stations, naval bases, or air force installations.

Unlike an ordinary neighborhood tavern, these establishments often display decades of aviation history. Visitors may find squadron patches, photographs, flight helmets, aircraft parts, call-sign boards, and memorials covering nearly every wall.

The atmosphere reflects the profession itself. Flying military aircraft requires tremendous skill, discipline, and teamwork. Consequently, aviator bars became places where pilots could relax among people who understood the challenges of the job.

For many aviators, these locations feel like a second home.

Why Are Aviator Bars Important?

Military aviation is a high-stress profession.

Pilots routinely train for dangerous situations and operate incredibly complex aircraft. They spend months away from family, deploy overseas, and shoulder enormous responsibility every time they fly.

As a result, aviator bars evolved into places where pilots could decompress and connect with their peers.

Several important functions emerged over time:

Building Camaraderie

Military units rely heavily on trust.

A pilot must trust wingmen, instructors, maintainers, and commanders. Therefore, informal social settings help strengthen those relationships.

Conversations that begin over a meal or a drink often build bonds that later prove valuable in the cockpit.

Preserving Squadron History

Many aviator bars serve as unofficial museums.

Squadron memorabilia often accumulates over decades. Plaques, photographs, challenge coins, and flight gear tell stories of deployments, victories, and fallen comrades.

As younger pilots arrive, they inherit the traditions and stories of those who came before them.

Mentorship

Experience is one of the most valuable commodities in aviation.

Senior pilots frequently share lessons learned with younger aviators in casual settings. These conversations may cover everything from flight techniques to leadership challenges.

In many cases, some of the most valuable lessons are taught far away from a classroom.

Honoring Those Lost

Unfortunately, aviation has always involved risk.

Many aviator bars include memorial displays dedicated to pilots who never returned from missions or training flights. Consequently, these establishments often become places of remembrance as well as celebration.

The Real Inspiration Behind the Hard Deck

The Hard Deck from Top Gun: Maverick was not a real bar.

The filmmakers constructed it as a temporary set on Breakers Beach at Naval Air Station North Island in Coronado, California. After filming ended, the set was dismantled.

However, the Hard Deck was inspired by real aviator hangouts.

One major influence was the legendary I-Bar at Naval Air Station North Island. For decades, Navy aviators gathered there after flights, training exercises, and deployments.

Another influence came from Trader Jon’s in Pensacola, Florida, a famous watering hole with deep roots in naval aviation culture.

Although these establishments differ in appearance, they share a common purpose: bringing aviators together.

The Meaning Behind the Name “Hard Deck”

The term “hard deck” comes directly from aviation.

In military flight training, the hard deck refers to a minimum altitude below which aircraft should not descend during certain training exercises.

Crossing the hard deck can create dangerous situations. Therefore, pilots treat it as a critical safety boundary.

The movie’s writers selected the term because it carried strong aviation significance while sounding memorable and authentic.

For pilots, the name immediately feels familiar.

How Accurate Is Hollywood’s Portrayal?

Movies often exaggerate reality.

Fortunately, Top Gun: Maverick captured several aspects of aviator culture surprisingly well.

What Hollywood Gets Right

The strong sense of camaraderie is absolutely real.

Military aviators develop close friendships through shared experiences. The joking, competition, storytelling, and good-natured rivalries shown in the movie closely resemble real interactions.

Likewise, squadron traditions and call signs play an important role in aviation culture.

Pilots genuinely use call signs, and many carry stories that range from hilarious to embarrassing.

The walls covered with memorabilia are also highly accurate. Real aviator bars frequently resemble aviation museums.

What Hollywood Exaggerates

The movie version is significantly more glamorous.

Most real aviator bars are not beachfront destinations filled with beautiful sunsets and attractive movie stars.

Instead, many are modest establishments located near military bases. Some resemble traditional pubs while others function more like officer clubs.

Additionally, modern military policies and regulations often place limitations on alcohol consumption, especially before flight operations.

As a result, the reality is generally more professional than what appears on screen.

Traditions Found in Aviator Bars

Aviator bars have developed countless traditions over the years.

Call Signs

Few traditions are more famous than pilot call signs.

These nicknames often originate from mistakes, embarrassing incidents, or personality quirks. Ironically, the less flattering the story, the more likely the name will stick.

Challenge Coins

Many military members carry challenge coins representing units, deployments, or achievements.

A spontaneous coin check can occur at any time. If someone cannot produce a coin, they may owe the group a round of drinks.

Squadron Patches

Squadron patches serve as badges of pride.

Visitors often exchange patches between units, creating colorful displays that document decades of aviation history.

Storytelling

Perhaps the most important tradition is storytelling.

Veteran aviators pass down lessons, humor, and history through stories that might otherwise disappear.

These tales help preserve the culture of military aviation for future generations.

Aviator Bars Around the World

The tradition extends far beyond the United States.

Military pilots from numerous nations maintain similar gathering places near air bases.

Whether in Europe, Asia, Australia, or North America, aviators often create informal spaces where they can socialize and strengthen unit bonds.

Although customs vary, the underlying purpose remains remarkably consistent.

Pilots seek connection with others who understand the unique demands of aviation.

Why These Places Continue to Matter

Modern communication technology has changed military life.

Pilots can now stay connected with family and friends through smartphones, video calls, and social media. Nevertheless, aviator bars remain important.

Face-to-face interaction still matters.

Shared experiences build trust. Stories preserve history. Traditions strengthen culture.

Moreover, aviator bars provide a sense of belonging that cannot be replicated online.

They remind pilots that they are part of something larger than themselves.

The Legacy of the Hard Deck

The Hard Deck may have been fictional, but its spirit was authentic.

For generations, aviator bars have served as gathering places where military pilots celebrate victories, mourn losses, mentor newcomers, and preserve the traditions of military aviation.

Hollywood gave audiences a romanticized version of these establishments. However, the real story is arguably even more fascinating.

Behind every squadron patch, call sign, and photograph on the wall lies a history of service, sacrifice, friendship, and adventure.

That legacy continues every time aviators gather after a flight and share stories with the next generation.

Final Approach

The next time you watch Top Gun: Maverick and see pilots gathered at the Hard Deck, remember that the scene reflects a genuine aviation tradition. While the movie set is gone, the culture that inspired it remains alive at military bases and aviator hangouts around the world.

The jets may capture the headlines, but the stories are often told after the engines shut down.

Few names in entertainment carry the same weight as Stan Lee. Even people who have never opened a comic book recognize his face, his voice, and his unforgettable catchphrase, “Excelsior!” More importantly, Stan Lee helped transform comic books from inexpensive newsstand entertainment into a worldwide cultural phenomenon.

From humble beginnings in New York City to becoming the public face of Marvel Comics, Stan Lee’s journey reads like one of the superhero stories he helped create. Along the way, he introduced audiences to flawed heroes, emotional storytelling, and larger-than-life adventures that still dominate movies, television, gaming, and pop culture today.

Without Stan Lee, the modern superhero landscape would look dramatically different. In fact, many of the world’s most recognizable heroes might never have existed at all.

Where Stan Lee Came From

Stan Lee was born Stanley Martin Lieber on December 28, 1922. His parents were Jewish immigrants from Romania who struggled financially during the Great Depression. As a child, Lee loved reading books, watching movies, and dreaming about becoming a great novelist someday.

Growing up in a tiny apartment with limited money forced him to develop a vivid imagination. Consequently, storytelling became both an escape and a passion. Lee admired adventurous heroes like Robin Hood and the swashbuckling movie stars of Hollywood’s golden age.

Before entering comics, Lee worked a variety of odd jobs. He delivered sandwiches, wrote obituary notices for a news service, and even helped write promotional materials. However, fate would soon place him in the comic book industry at exactly the right time.

How Stan Lee Entered the Comics Business

Stan Lee entered the comic world in 1939 at just 17 years old. He landed a job at Timely Comics, which would later become Marvel Comics. Initially, his duties were far from glamorous. He filled inkwells, fetched lunch, proofread pages, and handled small office tasks.

Nevertheless, Lee quickly impressed the company with his writing ability and enthusiasm.

His first published comic work appeared in Captain America Comics #3 in 1941. Interestingly, he used the pen name “Stan Lee” because he hoped to someday save his real name for writing the “Great American Novel.” Ironically, the pen name became legendary instead.

When World War II began, Lee served in the United States Army. During his military service, he worked as a writer, creating manuals, slogans, and training films. That experience sharpened his storytelling skills even further.

After the war, Lee returned to comics. However, by the 1950s, he had grown frustrated with the repetitive nature of traditional superhero stories. At one point, he even considered leaving the industry entirely.

Then everything changed.

The Birth of Marvel’s Revolutionary Heroes

In the early 1960s, comic books faced declining popularity. Meanwhile, rival publisher DC Comics found success with teams like the Justice League. In response, Marvel asked Stan Lee to create a new superhero team.

Instead of making perfect heroes, Lee decided to create characters with real human problems.

That decision changed comics forever.

Working alongside legendary artists like Jack Kirby and Steve Ditko, Stan Lee helped create a wave of iconic Marvel characters that redefined the genre.

The Superheroes Stan Lee Helped Create

The Fantastic Four

Released in 1961, the Fantastic Four became Marvel’s first major superhero team. Unlike traditional heroes, they argued constantly, struggled emotionally, and felt like a dysfunctional family. Readers loved them because they felt real.

The phrase:

“With great power comes great responsibility.”

became one of the most famous lines in entertainment history.

Silver Surfer

One of Marvel’s most philosophical and visually striking characters, the Silver Surfer debuted in 1966 as the cosmic herald of Galactus. Created by Stan Lee and Jack Kirby, the Silver Surfer explored deep themes of humanity, morality, loneliness, and redemption. Unlike many traditional superheroes, the Surfer often questioned mankind’s behavior while still believing humanity was worth saving. His cosmic adventures helped expand Marvel storytelling far beyond Earth and introduced readers to some of the most imaginative science fiction concepts ever seen in comic books.

How Stan Lee Changed the Comics Industry

Before Stan Lee’s rise, superheroes often behaved like perfect role models with little emotional depth. However, Lee introduced a revolutionary idea:

What if superheroes had everyday problems?

As a result, Marvel characters worried about rent, relationships, loneliness, self-doubt, and responsibility. Readers suddenly saw themselves inside comic books.

Furthermore, Stan Lee’s writing style felt conversational and energetic. He frequently spoke directly to readers through editor notes and letters columns. Consequently, fans developed a strong connection to both Marvel and its creators.

Lee also helped establish the idea of a connected comic universe. Characters crossed over into each other’s stories regularly, making Marvel’s world feel alive and interconnected.

Today, shared cinematic universes dominate entertainment largely because Marvel pioneered the concept decades earlier.

The Importance of Stan Lee’s Catchphrases

Stan Lee’s catchphrases became a huge part of Marvel culture. They gave comics personality and created a sense of community among readers.

“Excelsior!”

This became Stan Lee’s personal trademark. The word means “ever upward” or “still higher.” Lee often said he chose it because nobody else used it.

Eventually, “Excelsior!” became more than a slogan. It represented optimism, creativity, and the idea of always striving forward.

Buy “Excelsior!: The Amazing Life of Stan Lee” on Amazon: https://amzn.to/4uPTxtj

“Face Front, True Believers!”

Stan Lee regularly used this phrase when speaking directly to fans in comic columns and editor messages. It made readers feel like part of an exclusive club.

That sense of belonging helped create one of the most passionate fan communities in entertainment history.

“Nuff Said!”

Another classic Stan Lee phrase, “Nuff Said!” became shorthand for something so impressive that no further explanation was needed.

These catchphrases added charm and personality to Marvel’s brand while strengthening the emotional connection between readers and creators.

Stan Lee’s Hollywood Fame

For decades, Stan Lee remained well known mainly within comic book circles. However, the rise of Marvel films turned him into a worldwide celebrity.

Beginning with films like X-Men and Spider-Man, Stan Lee began appearing in cameo roles across Marvel movies.

Fans eagerly anticipated spotting him in every film. Sometimes he played a mailman. Other times he appeared as a bartender, security guard, or random bystander.

These cameos became beloved traditions that connected Marvel’s cinematic universe to its comic book roots.

The Lasting Legacy of Stan Lee

Stan Lee passed away on November 12, 2018, at the age of 95 in Los Angeles. Yet his influence remains impossible to escape.

Today, Marvel superheroes dominate theaters, streaming services, merchandise, conventions, and global pop culture. Billions of people know characters that began as sketches and ideas inside cramped comic book offices decades ago.

More importantly, Stan Lee proved that comics could tell meaningful stories about humanity, responsibility, prejudice, hope, and perseverance.

His heroes were powerful, but they were also relatable. That combination changed storytelling forever.

Excelsior Forever

Stan Lee was more than a comic book writer. He was a dreamer who helped millions of people believe that ordinary individuals could rise above fear, failure, and hardship.

Because of his creativity, generations of fans learned lessons about courage, sacrifice, and responsibility through colorful pages filled with heroes and villains.

Even now, his words continue to inspire audiences around the world:

“With great power comes great responsibility.”

Whether you grew up waiting for your Hogwarts acceptance letter or only recently discovered the magic, there is something endlessly fascinating about the spells used throughout the series. Some charms create light. Others summon objects or heal injuries. However, a few are so dark and dangerous that they are forbidden by wizarding law.

So grab your wand, avoid suspicious potions, and let’s journey into the magical world of Harry Potter.

Disclaimer: This article may contain affiliate links, including links to Amazon. As a result, we may earn a small commission from qualifying purchases at no additional cost to you.

What Is Harry Potter?

The Harry Potter and the Philosopher’s Stone series follows a young orphan named Harry Potter who discovers that he is actually a wizard. After years of living under the stairs with his cruel relatives, Harry receives a mysterious letter inviting him to attend Hogwarts School of Witchcraft and Wizardry.

Naturally, his life changes forever.

At Hogwarts, Harry befriends Ron Weasley and Hermione Granger while learning magic, flying broomsticks, brewing potions, and battling increasingly dangerous threats. Meanwhile, the dark wizard Lord Voldemort slowly regains power and seeks revenge against the boy who survived him as a baby.

Across seven books and eight films, the story grows darker and more intense. Nevertheless, friendship, bravery, sacrifice, and hope remain at the center of the saga.

Of course, one of the most exciting parts of the entire franchise is the magic itself.

What Are Harry Potter Spells?

In the wizarding world, spells are magical commands spoken aloud while using a wand. Although some advanced wizards can perform silent magic, most spells require an incantation and a specific wand movement.

Interestingly, many spell names are inspired by Latin words. Consequently, the spells often sound ancient and mysterious. For example, “Lumos” comes from the Latin word for light, while “Expelliarmus” roughly translates to driving out a weapon.

Some spells are practical and harmless. Others are terrifying weapons capable of destruction or death.

Now let’s explore the spells that made the Harry Potter universe unforgettable.

The Most Famous Harry Potter Spells Explained

Expelliarmus – The Disarming Charm

Perhaps no spell is more associated with Harry himself than Expelliarmus.

This spell forces an opponent’s wand or weapon from their hand. While many wizards prefer aggressive combat magic, Harry consistently chooses disarming over killing. Therefore, Expelliarmus becomes a symbol of his character and morality.

Ironically, Voldemort often recognizes Harry by his repeated use of this spell.

The Unofficial Ultimate Harry Potter Spellbook: A complete reference guide to every spell in the realm of wizards and witches

Lumos – Creating Light in Darkness

Lumos creates a glowing light at the tip of the wand.

Although simple, this spell appears constantly throughout the books and films. Wizards use it while exploring dark corridors, hidden caves, and forbidden forests. Furthermore, fans around the world still jokingly say “Lumos” when turning on flashlights.

Its counter-spell is “Nox,” which extinguishes the light.

Wingardium Leviosa – The Levitation Charm

Few scenes are more iconic than Hermione correcting Ron’s pronunciation:

“It’s levi-O-sa, not levio-SA!”

This spell allows witches and wizards to levitate objects through the air. Although it seems basic at first, it becomes an essential magical skill throughout the series.

Feathers, chess pieces, trolls’ clubs, and countless other objects float thanks to Wingardium Leviosa.

Accio – The Summoning Charm

Accio allows the caster to summon objects from great distances.

Harry famously uses this spell during the Triwizard Tournament to call his broomstick during a dragon challenge. As a result, Accio becomes one of the most practical and useful spells in the wizarding world.

After all, who wouldn’t want magical remote control over everything in the house?

Alohomora – Unlocking Doors

Alohomora unlocks doors and windows magically.

Hermione uses it early in the story to help the trio sneak around Hogwarts. However, some magical locks resist the spell entirely.

Still, it remains one of the most recognizable utility charms in the franchise.

Stupefy – The Stunning Spell

Stupefy knocks targets unconscious without causing permanent harm.

Aurors, professors, and students alike use this spell during combat. Additionally, multiple Stunning Spells fired together can create enormous force.

Unlike darker curses, Stupefy is considered defensive magic rather than evil magic.

Protego – The Shield Charm

Protego creates a magical shield that blocks incoming spells.

During battles, skilled duelists rapidly cast Protego to defend themselves. Consequently, magical combat in Harry Potter often resembles a deadly chess match of attacks and defenses.

Advanced versions of the spell can protect entire buildings.

Harry Potter and the Cursed Child, Parts One and Two: The Official Playscript of the Original West End Production

Dark and Dangerous Magic

Avada Kedavra – The Killing Curse

This is the most feared spell in the wizarding world.

Avada Kedavra instantly kills its victim with a flash of green light. Worse yet, there is no normal defense against it.

Voldemort uses this curse repeatedly throughout the series. In fact, Harry survives the curse as a baby, earning the title “The Boy Who Lived.”

The curse belongs to the three infamous Unforgivable Curses.

Crucio – The Cruciatus Curse

Crucio inflicts unbearable pain upon the victim.

Unlike physical torture, the pain comes directly from dark magic itself. Therefore, this curse is considered especially horrifying.

Bellatrix Lestrange frequently uses Crucio with terrifying enthusiasm throughout the films.

Imperio – The Imperius Curse

Imperio allows the caster to completely control another person’s mind and actions.

Victims often feel strangely calm while under the curse. As a result, many people commit crimes without realizing they were manipulated.

The Ministry of Magic strictly forbids this spell.

Sectumsempra – Snape’s Deadly Secret

This dark curse creates deep magical slashes across the victim’s body.

Harry discovers the spell inside an old potion textbook once owned by Severus Snape. Unfortunately, he uses it without understanding its horrifying effects.

The scene remains one of the darkest moments in the series.

Defensive and Protective Spells

Expecto Patronum – The Patronus Charm

This spell creates a magical guardian called a Patronus.

Patronuses protect against Dementors, horrifying creatures that feed on happiness and hope. To cast the spell successfully, the wizard must focus on an intensely happy memory.

Harry’s Patronus famously takes the form of a stag.

Many fans consider this the most beautiful spell in the entire franchise because it symbolizes hope overcoming darkness.

Finite Incantatem – Ending Magic

Finite Incantatem cancels or stops ongoing magical effects.

Although not flashy, this spell proves incredibly useful when things spiral out of control.

Given how often magic goes terribly wrong at Hogwarts, that happens quite a lot.

Petrificus Totalus – The Body-Bind Curse

This spell temporarily paralyzes the victim completely.

Hermione memorably uses it on Neville Longbottom during the first story. Later, the spell appears throughout numerous magical confrontations.

The victim remains conscious but cannot move.

Strange, Funny, and Unusual Spells

Not every spell in Harry Potter is dangerous. In fact, many are downright ridiculous.

Rictusempra – The Tickling Charm

This spell causes uncontrollable laughter and tickling.

While hardly deadly, it can distract opponents during a duel.

Tarantallegra – The Dancing Curse

Tarantallegra forces the victim’s legs to dance wildly out of control.

The spell creates hilarious scenes in both the books and movies.

Eat Slugs Curse

Ron accidentally backfires this curse on himself in Harry Potter and the Chamber of Secrets.

The result is exactly as disgusting as it sounds.

Engorgio – Enlarging Objects

This spell enlarges objects dramatically.

Although useful in theory, magical enlargement often creates chaos instead of convenience.

Why Harry Potter Spells Became So Popular

The magic system in Harry Potter feels believable because the spells follow rules and structure. Moreover, the spells are memorable, easy to pronounce, and tied to emotional moments in the story.

Fans still shout “Expelliarmus!” while playing games. Theme parks recreate wand duels for visitors. Meanwhile, countless people know exactly what someone means when they say “Expecto Patronum.”

Very few fictional worlds have created language so deeply embedded in popular culture.

The Legacy of Harry Potter Magic

More than two decades after the first book appeared, Harry Potter remains one of the most influential fantasy franchises ever created. The spells are a huge reason why.

Magic in Harry Potter is not just about power. Instead, it reflects personality, emotion, morality, and choice. Harry uses defensive magic because he values life. Voldemort uses killing curses because he fears weakness. Meanwhile, Hermione masters practical spells because intelligence and preparation define her character.

That deeper meaning gives the magic emotional weight far beyond flashy special effects.

Even today, millions of fans continue rereading the books, rewatching the films, and debating their favorite spells online. Clearly, the wizarding world still casts a powerful spell over audiences everywhere.

So, which spell would you choose if you attended Hogwarts?

Would you master defensive magic like Harry, powerful curses like Voldemort, or clever utility spells like Hermione?

Drop your favorite Harry Potter spell in the comments and tell us why it stands out to you!
