46 Surprising Real Photos Explained, From Pyrite to the Hoover Dam

A Child’s Skull Before Losing Baby Teeth

With photo-editing apps on every phone, it is natural to assume that any astonishing picture is fake. Yet many of the strangest images online are perfectly real: a mineral that grows in near-perfect cubes, a fish that swallows prey longer than itself, a dam photographed before its lake filled, a cabinet carved to look like a corrupted video file. The trick is knowing the story behind each one.

This collection of 46 surprising photos, first gathered in an Imgur album, is organised by theme: natural patterns, the living world and the human body, clever engineering, remarkable places, art and craft, and moments from history and film. For every image we explain what you are looking at, why it matters and, where the original caption was wrong or doubtful, what the evidence actually says. A few corrections are worth flagging up front: the "Bermuda Triangle" shipwrecks are almost certainly in Australia, the Manhattan reconstruction shows the island about 400 years ago rather than 600, and the "world's deepest pool" lost its title long ago. Where we could not confirm a claim, we say so. The final section offers a few quick checks you can use to judge whether an amazing photo is genuine.

Patterns made by nature and physics

Pyrite cubes growing from rock

Perfect Cubes of Pyrite Formed by Mother Nature

These metallic cubes were not cut by anyone. Pyrite, iron disulfide (FeS₂), crystallises in the cubic system and often grows as sharp-edged cubes, with some of the finest specimens coming from Navajún in La Rioja, Spain. Its brassy shine earned it the nickname "fool's gold", and its name comes from the Greek for fire, because it sparks when struck.

Bismuth's rainbow staircase

Bismuth Is a Chemical Element With An Amazing Iridescent Oxide Surface

Bismuth is a heavy metal that melts at about 271 °C, low enough to grow crystals on a kitchen stove. As it cools, the edges of each crystal grow faster than the centres, creating stepped "hopper" shapes. The rainbow colours come from a very thin oxide layer whose uneven thickness makes reflected light interfere, the same effect seen in soap bubbles. Most showpiece crystals like this are grown in a lab or workshop.

The geometry inside a red cabbage

Slice a red cabbage across the middle and its tightly packed leaves form a rippling, almost star-shaped pattern around the core. Each fold is a leaf that grew while squeezed between its neighbours, which is why the layout looks both regular and wild.

Lightning's signature in the grass

The branching brown lines on this golf course are a Lichtenberg figure, the pattern left when a powerful electrical discharge spreads out from a point. When lightning hits the ground, current races outwards through the moist soil and scorches the grass along its path. Similar fern-like marks can appear briefly on the skin of people struck by lightning.

A "UFO" made of cloud

Lenticular clouds form when moist, stable air flows over mountains and creates standing waves downwind; where the air rises and cools, it condenses into a smooth lens shape. Because they stay in place rather than drifting, they are often mistaken for flying saucers. Glider pilots seek them out for the strong rising air they mark.

A sunset with a bite out of it

Sunset and Eclipse Happening at the Same Time

Two people on a rocky shore watch the Sun set as a thin crescent, because the Moon is passing in front of it. Partial and annular eclipses sometimes coincide with sunrise or sunset for a given location, producing this rare horned shape on the horizon. The date and place of this particular photo are not recorded in the original album.

Glass that melted in a fire

The drooping, icicle-like mass is window glass that softened and sagged in the heat of a building fire. Glass has no single melting point; it gradually softens as it heats, and a fully developed house fire can get hot enough to make panes slump like wax.

The Fukang meteorite

Found in 2000 in the mountains near Fukang in Xinjiang, China, this is a pallasite, a rare stony-iron meteorite in which gem-quality olivine (peridot) crystals sit in a nickel-iron metal. The main mass weighed about 1,003 kg and is estimated to be around 4.5 billion years old. Thin, polished slices glow golden when backlit, as here. Researcher Marvin Killgore, who studied it, holds the remaining main mass.

Animals and the human body

A sea turtle on a jellyfish

Sea turtles really do eat jellyfish, and some species seek them out. This particular image, though, with its glowing gold turtle and perfectly lit background, looks more like digital art or a heavily edited composite than a straight photograph, and we could not trace its original creator.

A lizard's face, shed in one piece

Reptiles regularly shed their outer skin as they grow. Many lizards shed in patches, but sometimes the skin of the head comes away whole. Geckos and some other lizards have a transparent scale over each eye instead of eyelids, which is why clear "lenses" are visible in this delicate cast.

The black swallower

A Fish That Eats Prey Up to 10x Its Mass and Twice Its Length

The black swallower (Chiasmodon niger) is a deep-sea fish usually 15 to 20 cm long that lives between roughly 700 and 2,700 metres down. Its stomach stretches enough to hold prey more than twice its length and about ten times its mass. In 2007 a 19 cm specimen was found dead off Grand Cayman with an 86 cm snake mackerel inside it; when prey is too big to digest before it rots, gases can float the swallower to the surface, which is how most specimens have been found.

A child's skull before the baby teeth fall out

This prepared skull, with the bone cut away, shows something every child carries: the adult teeth waiting above and below the milk teeth. The permanent teeth gradually push up and dissolve the roots of the baby teeth, which is why milk teeth fall out so easily. Most children start losing them at about six years old.

A CT scan in three dimensions

You Won’t Believe How Accurate GE’s New CT Scanner Is

This image of a head and neck, with blood vessels picked out in red, is a 3D reconstruction from a computed tomography (CT) scan, reportedly made on a GE scanner. Modern CT takes hundreds of thin X-ray slices and software stacks them into a volume that doctors can rotate and "peel" layer by layer, which helps in planning surgery and spotting vessel problems.

How a cat sees the world

Human Vision (Top) vs. Cat Vision (Bottom)

The lower half of this comparison simulates feline vision: a wider field of view (about 200 degrees against our roughly 180), blurrier detail, muted colours and much better performance in dim light. Cats need roughly one-sixth of the light we do, thanks to more rod cells and a reflective layer behind the retina, but their distance acuity is estimated at around 20/100 to 20/200.

Engineering and everyday technology

A machine that lays brick paths

This yellow machine, marked Tiger-Stone, is reportedly a Dutch invention that lets workers drop bricks into a hopper; gravity slides them down into a ready-made herringbone surface as the machine creeps forward. The Red Cross sign ("Rode Kruis") in the background suggests the photo was taken in the Netherlands, where brick streets are common.

Inside a Patek Philippe movement

The Internal Mechanism of a Watch by Patek Philippe, Considered the Finest Watchmaker in the World

These are the two faces of a complicated mechanical watch movement from Patek Philippe, the Geneva watchmaker founded in 1839 and often ranked among the most prestigious in the world. Hundreds of tiny parts, with synthetic rubies as low-friction bearings, are finished by hand even where no one will ever see them.

Cross-section of a subsea power cable

The original caption called this an undersea cable, which is true, but it is not the kind that carries the internet. The three thick copper cores show this is a high-voltage power cable; data cables are much thinner and carry hair-fine optical fibres. The ring of steel wires around the outside is armour that protects the cable on the seabed.

Slicing through an airliner

This cutaway of a wide-body aircraft fuselage, apparently on display in a museum hall, shows how the cabin sits above a cargo hold filled with standard Lufthansa luggage containers. The round cross-section is no accident: a cylinder is the most efficient shape for holding the pressurised air passengers breathe at cruising altitude.

A soda bottle before it is a bottle

What a Liter Bottle of Soda Looks Like Before Compressed Air Is Added

The small test-tube shape is a PET plastic "preform". The threaded neck is already its final size; the rest is heated and blown into a mould with high-pressure air, stretching it into a full-size bottle, which is filled afterwards. Shipping preforms instead of empty bottles saves a great deal of space.

Power strip liberators

Bulky plug-in adapters often block neighbouring sockets. Short extension leads, sometimes sold as "power strip liberators", move each adapter away from the strip so every outlet can be used. Do not overload the strip's total rating.

A cryptex USB drive

Inspired by the combination-lock cylinder in Dan Brown's The Da Vinci Code, this brass USB stick slides out only when the rings spell the right code. It offers physical privacy against casual snooping, but the data inside is not encrypted unless you add software protection.

A 3D-printed ventilated cast

This 3D-Printed Cast Uses Ultrasound to Heal Bones 40% Faster

This lattice cast is the Osteoid, a concept design by Turkish designer Deniz Karasahin, reportedly from 2014. It was designed to be printed to fit the limb and to hold a low-intensity pulsed ultrasound unit, a therapy some studies link to faster bone healing. The "40% faster" figure in the original caption comes from claims about ultrasound therapy, not from trials of this cast, and should be treated with caution.

Remarkable places and structures

A fence across the Algodones Dunes

Algodones Sand Dunes Curvy Border Fence in Southern California

The Algodones Dunes in southeastern California run for about 72 km near the Mexican border and have stood in for alien deserts in films such as Return of the Jedi and Stargate. Because the sand constantly shifts, a fixed wall would quickly be buried; the border barrier here has reportedly been built in sections that can be lifted as dunes move, which is why it rides up and down the slopes.

Nemo 33, a pool for divers

World’s Deepest Swimming Pool – 113 Ft. Deep and Holding 600,000 Gallons

The pool in this photo is Nemo 33 in Brussels, opened in 2004 for diver training, with a deepest point of 34.5 m (113 ft) and about 2.5 million litres of water. It once held the record for the world's deepest indoor pool, but was overtaken by Y-40 in Italy in 2014, then Deepspot in Poland, and in 2021 by Deep Dive Dubai at just over 60 m.

Twisting brickwork

Horizontally Spiraled Bricks On a New Restaurant Building

The pillars of this building appear to spiral sideways, but every brick is straight. Bricklayers create the effect by setting each course at a slightly different angle so the rows seem to twist as they rise and arch. The original caption said it was a new restaurant; we could not confirm the building's location.

A railway carriage turned footbridge

An old, rusting passenger carriage has been laid across a stream to serve as a covered bridge. Steel railcars are long, strong and cheap once retired, so reusing them for crossings or sheds is a familiar rural improvisation. The location is not recorded.

Space Mountain with the lights on

This Is What Space Mountain Looks Like With the Lights On

Space Mountain is Disney's indoor roller coaster, first opened at Walt Disney World's Magic Kingdom in 1975, with versions in other Disney parks. Riders normally race through darkness lit only by "stars"; switching on the work lights reveals a dense steel frame and track packed closely together, which explains why the ride feels so fast.

A road between ice floes

Seen from directly above, a road or causeway runs through dark water crowded with round plates of floating ice. Rounded floes like these form when slushy ice bumps and grinds against itself in moving water. The exact location is not given in the original album.

Shipwrecks in turquoise water

Sand Bar Off the Bermuda Triangle That Caught 16 Ships

The original caption placed this line of wrecks near the Bermuda Triangle, but the scene closely matches the Tangalooma Wrecks off Moreton Island in Queensland, Australia, where old vessels were reportedly sunk on purpose to form a breakwater for small boats. The site is now popular for snorkelling and diving. There is no evidence a sandbar "caught" them.

A road across a runway

The Runway at the Gibraltar International Airport Has a Road Crossing It

At Gibraltar International Airport, Winston Churchill Avenue, the main road to the Spanish border, crossed the 1,776 m runway, and traffic was stopped with barriers every time a plane landed or took off. Since 31 March 2023 most vehicles use a new route, Kingsway, which passes through a tunnel instead.

Manhattan in 1609

Present Day Manhattan Versus What It Would Have Looked Like 600 Years Ago

The green half of this image comes from the Mannahatta Project, led by landscape ecologist Eric Sanderson with the Wildlife Conservation Society, which reconstructed the island's forests, streams and wetlands as they were in 1609, when Henry Hudson's crew arrived. That is about 400 years ago, not 600 as the original caption said. The work was published in the 2009 book Mannahatta: A Natural History of New York City.

Art, craft and monuments

A wave in coloured pencil

Intricate Colored Pencil Drawing of a Wave

This curling wave, lit from within by a sunset, was drawn with coloured pencils, some of which are lying beside it. Building up such rich colour means layering many light coats and burnishing them together, a slow technique that can take days for one image. We could not confirm the artist's name.

An eggshell turned to lace

This Eggshell Has More Than 20,000 Holes Drilled in It

Eggshell carving is a traditional craft in parts of Central Europe. Pieces like this, with tens of thousands of tiny holes forming flowers and grapevines, are widely credited to Slovenian artist Franc Grom, who is known for drilling eggshells into lace-like patterns. One slip can crack the whole shell.

Swords in the Rock, Norway

Sverd i fjell Giant Sword Monument in Norway

Sverd i fjell ("Swords in Rock") stands beside the Hafrsfjord near Stavanger. The three 10-metre bronze swords by sculptor Fritz Røed, completed in 1983, commemorate the battle of Hafrsfjord in 872, traditionally seen as the moment King Harald Fairhair united Norway. The largest sword represents Harald; the smaller two, the kings he defeated.

A cabinet with a digital glitch

A Cabinet Carved to Look Like a Digital Glitch

This ornate wooden cabinet looks as if it has been hit by a video glitch, with its carvings smeared sideways. It is widely credited to Italian designer Ferruccio Laviani, who made a series of computer-controlled carved "glitch" pieces for the furniture maker Fratelli Boffi. The joke is that classical craftsmanship has been "corrupted" like a bad file.

The Lion Monument, Lucerne

Wounded Lion Sculpture in Honor of Swiss Guards Who Died in the French Revolution – Luzern, Switzerland

Carved into a former sandstone quarry in 1820–21 to a design by Danish sculptor Bertel Thorvaldsen, the dying lion honours the Swiss Guards killed on 10 August 1792, when revolutionaries stormed the Tuileries Palace in Paris. The Latin inscription dedicates it to the loyalty and bravery of the Swiss. Mark Twain called it the most mournful and moving piece of stone in the world.

A wolf made of pipe cleaners

Artist Designs a Wolf Out of Pipe Cleaners

Pipe cleaners, the fuzzy craft wires used in classrooms, have been bent, layered and trimmed to build a life-size wolf with convincing fur and posture. Working in a humble material is part of the appeal. The artist is not named in the original album.

A "loaf" of layered art

Loaf of Art. Each Color Was Layered to Form the Picture. Apparently Each Slice Sold for $5000.

These blocks, built up from many coloured layers so that each slice reveals a picture, show how images can be hidden inside a solid object, a principle similar to millefiori glass. The original claim that each slice sold for $5,000 could not be verified, and we could not identify the maker.

Coins stacked beyond the edge

Coins Stacked in Such a Way That They Extend Past the Edge of the Table

These coin stacks curve out past the edge of a table and seem to defy gravity. The secret is balance: as long as the combined centre of mass stays over the table, the structure holds, and careful placement lets the coins bridge like an arch. Japanese coin-stacking artists have made this kind of sculpture popular online.

History, film and photography

Space Shuttle Atlantis seen from orbit

View of Space Shuttle Atlantis from the International Space Station

This photo, taken from the International Space Station, reportedly shows Space Shuttle Atlantis as a bright streak far below against Earth's clouds. Atlantis flew the last mission of the shuttle programme, STS-135, landing at Kennedy Space Center on 21 July 2011, and ISS crews photographed shuttles during their visits.

The Hoover Dam before Lake Mead

Rarely Seen Back of the Hoover Dam Before It Was Filled with Water in 1936

Most photos of the Hoover Dam show its curved downstream face; this one shows the upstream side, with the intake towers that would later stand in the lake. Lake Mead began filling on 1 February 1935, so the picture dates from about 1934–35, slightly earlier than the "1936" in the original caption. The dam was handed to the federal government in March 1936.

Marlon Brando becomes Don Corleone

Marlon Brando Before and After His Makeup Was Done for His Role in the Godfather

For The Godfather (1972), Brando, then in his late 40s, was aged on screen with greyed, thinned hair, shadowing and a jowly jaw. He reportedly stuffed his cheeks with cotton for his screen test, and a dental appliance was used during filming, giving the Don his famous mumble. The role won him the Academy Award for Best Actor.

Adolf Hitler in the First World War

Hitler Had to Cut His Moustache to Fit Into a Gas Mask. This Is How He Looked Before

This photo shows Hitler as a soldier in the Bavarian army during the First World War, with a full, curled moustache. A story reported in 2007 says he trimmed it to fit under a gas mask, based on an unpublished essay by Alexander Moritz Frey, who served in the same regiment. It is a single recollection, so it remains plausible but unconfirmed.

A million colours in one image

There Are 1 Million Different Colors in This Picture

This grid is a 1,000 by 1,000 pixel image designed so that every pixel is a different colour, one million in total. Standard 24-bit screens can display about 16.7 million colours, so it is well within range. Copies resized or compressed for the web, like this one, merge many pixels and no longer contain all million.

Fireworks, out of focus

Fireworks, When the Camera Refocuses During the Explosion

Shifting the camera's focus during a long exposure turns each spark of a firework into a soft, spiky shape, so the burst looks like a cactus or a sea creature. Photographers use this "focus pull" deliberately for abstract effects.

One photograph, not four

This looks like four separate pictures, each in its own colour theme, but it is a single photograph of a carefully arranged set. Objects are placed and painted so that colour boundaries line up exactly from the camera's viewpoint; look closely and items such as the brass lamp cross between the "panels".

How to tell if a surprising photo is real

Many of the images above were doubted online at first, and some captions turned out to be wrong even when the photos were real. A few checks help. Run a reverse image search to find the earliest version and the original photographer. Look for a named place and date; real photos can usually be anchored to both. Be wary of round-number claims ("600 years", "$5,000 a slice", "40% faster"), which often travel without a source. And remember that a real photo can still carry a false caption, as the "Bermuda Triangle" wrecks show.

The best surprises survive the checking. A cube of pyrite, a seven-inch fish with a three-foot meal and a dam photographed before its lake filled are more interesting once you know they are true.
