Characters traveling in an unfamiliar area choose to stop at a landmark. They discover that it's not terrain, it's something, and much bigger than that something has any right to be. The specific something can vary considerably, but it's typically either a living entity, its remains, or something created by living entities, such as a building, a vehicle or the like. Often accompanied by a Reveal Shot.
Common Subtropes of this trope include characters finding out that the giant crater is actually a giant footprint, that an asteroid, moon, planet or other astronomical body is a gigantic spaceship or station, that the asteroid cave you're hiding in is a giant space slug, or that a mountain, hill, or island is a sleeping giant/troll/turtle/earth elemental. Sometimes, the elephant is the room, metaphorically, and entire world you're on is a giant turtle. Or maybe it's still just the kind of place you thought it was, but alive.
For ships/stations that may literally be confused with moons (or planets), see Planet Spaceship. See also Big Dumb Object and Dyson Sphere. If it's a real-world location, may overlap with Weaponized Landmark. Whatever the actual object turns out to be the discovery of it can often lead to an Oh, Crap! moment. Contrast No Mere Windmill, Genius Loci.

Asuka had asked where, and Ching had pointed at the faintly visible glow of one of the half-moons overhead. That was no moon, it turned out.

The ones described in the story include Whiskers Whitetail, better known to the ponies as the Whitetail Woods; Emberstoke the Eternal, who in his sleep forms a large volcanic caldera; and Tartarus, who when awake decided that the best way to contain powerful, evil creatures was to devour them and imprison them in his cavernous gut.

Then the mountain sits up and looks at him, revealing itself to be a several-stories-high naked woman. Alfred was digging into her gurgling stomach.

- The Adventures Of Baron Munchausen features the baron finding an island that turns out to be a giant fish.
- Bas-Lag Cycle: The Scar, Bellis finds out what it is Armada is looking for by means of a drawing in a book. It takes her a moment of looking at the drawing to realize that the immense set of concentric circles in the depths of the sea represent an immense eye.
She still did not take her gaze from the picture she held: a little man in a little ship on a sea of frozen waves that overlapped in perfect sequence-like fish scales, and below them deeps rendered in crosshatched and tightly spiraled ink, and at the bottom, easily eclipsing the vessel above, a circle in a circle in a circle, vast no matter how vague the perspective, unthinkably big, with darkness at its center. Looking up, looking up at the fisherman hunting his prey.

- The Silver Chair:
- Eustace, Jill, and Puddleglum stop to look at the far-off gigantic statues lying in a field. Jill remarks on how lifelike they look. Then they stand up and start throwing rocks the size of cars. Fortunately, the giants were throwing at each other as a game; unfortunately, they have lousy aim.

They later learn that blasting sonar tends to chase away any mountain-fish in the area, so it becomes SOP for all ships traversing seas and oceans.

- The Light Fantastic: A team of thieves find a cave full of diamond stalactites and stalagmites high up on a mountain and think they've hit the jackpot. However, the diamond structures turn out to be troll teeth — and still in the huge, ancient troll's mouth. In later books, this is said to be the root of all the animosity between trolls and dwarfs. The dwarfs go about innocently mining for diamonds, only to be severely beaten by a troll who is woken up from his nap by someone trying to steal his teeth.

The mooks the protagonists have been fighting inside are the immune system of the creature.
- Empire from the Ashes: In Mutineers' Moon, the Moon is no moon. It's a light picket cruiser with enough firepower to make the Death Stars seem weak in comparison, that threw the original Moon into the Sun and secretly replaced it 50,000 years ago. Oddly enough, this is the least outrageous plot point.
- Shel Silverstein: "Hungry Kid Island", in Falling Up, is simply the grass- and tree-covered scalp of a very large, hungry child sitting on the sea floor.

- Humanx Commonwealth: In Reunion, Alan Dean Foster appears to play this straight from the Star Wars example, with an artificial object orbiting an otherwise uninteresting gas giant. A bit larger than Earth's moon, it appears to be a colossal space station, or even possibly a warship. However, it one-ups the Trope Namer when it turns out the "moon" is a lifeboat. You know, those tiny things that carry only a small fraction of the parent ship's passengers and crew. Turns out the real warship is the gas giant. Said "gas giant" is slightly larger than Jupiter, which is itself 1320 times larger than Earth by volume.
- H. P. Lovecraft:
- "Imprisoned With the Pharaohs," this serves as the kicker, when the hero encounters a huge "five-headed beast" emerging from the shadows of an Egyptian tomb. This turns out to be only the paw of the gigantic monster that the Sphinx originally portrayed.

In the sequel, Redemption Ark, the Inhibitors break down three worlds to create an enormous weapon, which is used to turn a star into a flamethrower. The third book in the trilogy, Absolution Gap, a gas giant is revealed to be a transport mechanism for creatures from another dimension. Alastair Reynolds really likes this trope.
- Ringworld has a supersized example where the sun that Ringworld orbits can be manipulated to emit photon bursts through solar flares. The Great Ocean of Ringworld has some surprises of its own. Not only does it contain real "island-fish" that sailors can accidentally land on, but also archipelagos which are precise maps of various populated Known Space planets: Earth, Kzin, Jinx, etc. Precise, one-to-one scale maps.
- The Seventh Tower: Cavernmouths are giant, lightning-fast ambush predators that lurk in caves and open their mouths to fill the cave entrance. Tal narrowly avoids falling victim to one when he realizes that the cave they're about to enter has tonsils.

Queen Louise waves off concern over this mode of transportation (citing her experience being shuttled about on couriers maybe twice the size of a horse), then asks Laurence "Is that your dragon on the hill over there?"...before the "hill" lifts his head to look at her.
Laurence saw no hill, and then realized she was pointing at the middling-sized Berghexe sleeping on Temeraire's back. Before Laurence could correct her, Temeraire himself lifted up his head and looked in their direction. "Oh," she said, a little faintly.
- Theatre Of The Gods: The crew of the Necronaut find their ship in a dark, swampy world. It turns out that they were inside a "Sweetie" which is a giant slug-like monster with tentacles and extendable arms. The "Sweetie" they were in was over 10 kilometres long and that was just a pupa. Later on in the book, there's an adult "Sweetie" and it's bigger than many superplanets and easily wipes out a religiously fanatical starship battlefleet. It also easily breaks out of the gravitational pull of a nearby black hole.
- Venus Prime: Amalthea (one of Jupiter's moons) turns out to be have a huge starship inside it belonging to a race of Starfish Aliens, who had originally come to colonize Venus but failed.

When the father wakes up, he runs out of the ship and assumes that the Colonials are the Eastern Alliance, a fascist nation on the planet Terra (no, it's not Earth). When they tell him that they're aboard a ship, he doesn't believe them, as no ship could be that large.
- Doctor Who:
- "42" has a good take on this trope. That's no Sun. Oh wait, it is a Sun. Oh wait, the Sun is alive...
- "The Beast Below": The Doctor describes Starship UK as "that's not just a ship, that's an idea, that's a whole country". Skyscrapers have neon signs bearing the names of counties.Then it turns out Starship UK's engines are dummies because the whole structure is built on the back of a star whale!
- "The Big Bang": All the stars in the universe have been wiped out so why does Earth still have a sun? Because that's no sun, it's the exploding TARDIS!
- Finally, the most faithful take on this trope possible comes in "Kill the Moon": that Moon really is no moon. It's an egg.
- In the Farscape episode "Green Eyed Monster", the line "That's no moon!" is used word for word by Crichton. It's not a space station however, it's a "budong".

- In the series finale of M*A*S*H, Klinger points out to Col. Potter the beautiful sunset over the hills. Col. Potter then says it would be a beautiful sunset...if they were actually facing west. He quickly realizes that a fire is approaching, and the 4077th better bug out and fast.

- At one point in The Hitchhiker's Guide to the Galaxy (original radio show version), the ship's Improbability Drive causes it to rematerialise in what seems to be a strange cylindrical cave on the planet of Brontitall. The cave is a mile deep, ice-cold and apparently carved out of marble.

Oh, and a society of birds now live in Arthur's right ear.
- Astra includes a creature called Parmaelosthu, a giant floating blob that looks exactly like a small island until you try to climb onto it and discover it's made of slime. The book leaves it an open question whether it is intelligent or not.
- Cthulhu Mythos: One of the Outer Gods is Ghroth, a moon-shaped planetoid that travels through the universe. Whenever it gets close enough to a planet, it sings a song that brings about the end of the world.

On a successful Idea roll, the character realizes that the planet is actually opening its eyes. Roll 1d10/1d100 SAN [roll to see how many Sanity Points you lose], and thank you for playing."
- Dungeons & Dragons:
- Zaratans appear in the Arabian Nights-themed Al-Qadim setting, and have since become a D&D staple.

- The Leviathan is so big that its body, covered by eons of sediment, soil and rock, has in many places become a part of the landscape, forming great ridges, islands and peaks settled by marine and terrestrial beings who have no idea what kind of entity they live on. What's initially taken to be a towering temple-spire to Leviathan is, in fact, just one of its hollowed spines.
- The lukhorn worm is a relative of the purple worm that dwells in the Underdark and likes to pretend being a tunnel entrance. It's so hard to spot that entire drow patrols have ended up getting Swallowed Whole.
- Exalted: Both the sun and the moon are gigantic eons-old artifacts attuned to the sun god and moon god of the setting, respectively. The Silver Chair of Night is a vast reality engine, drawing in forces from other realms to bring both dynamism and stability to Creation, and the Dirigible Engine Daystar is, aside from serving all of the functions of our sun and fueling Holy effects, the mightiest weapons system Creation has ever known, surpassing even the Realm Defense Grid. The Daystar can also fold itself into a giant robot. And it knows Kung Fu.
- Legend of the Five Rings features the Kusatte Iru, a sleeping demon so large that humans can navigate its blood vessels like tunnels.
- Rogue Trader: Name-dropped in a quote describing the Void Kraken, where a starship captain has dismissed the creature as simply a moonlet but a crewman is very much convinced that the giant monster isn't any sort of moon.
"The cap't, he said it was just a moon at first and to think no more on it, but I's knew better. I told him I did, I says to him that there is no moon..."
- RuneQuest: True Dragons are very, very, very large, and their tendency to sleep the ages away and not move much even when awake usually leads them to become covered in soil and plant life until they become indistinguishable from the landscape. The result is that, while they're not actually especially rare, few people know precisely which rocky ridges, hills and small mountain ranges are actually sleeping dragons. During the legendary Dragonkill Battle, the ill-fated human army only fully realized how badly they'd miscalculated things when a considerable number of the mountains surrounding the battlefield stood up, shook off their coverings of soil and rock, and attacked.
- Warhammer: Age of Sigmar: After Behemat, an ancient titan of immense size, fell into slumber after losing a battle with Sigmar, he became covered by soil and rock and was eventually buried under he was indistinguishable from the landscape. His recumbent form became known as the Scabrous Sprawl, and eventually people forgot that its valleys, ridges and hills were simply the soil-covered body parts of an immense titan...until he woke up.
- Werewolf: The Apocalypse: In the Revised edition, the intro story, told by a werewolf prophet, has him relating one of his dreams, talking about how massive the Wyrm is. How massive?

- Major spoiler: It turns out that the entire Matoran "universe" is inside Mata Nui, who's a Humongous Mecha that crash-landed on a planet. The island that bears his name is (was) actually a covering on his face. Since it was a lava island, one can only assume he had allergies.
- Likewise, the Red Star that orbited that planet was revealed to be a planet-sized Space Station where the dead characters were recreated, and also served as a booster rocket that attached to Mata Nui when he flew through the cosmos.
- Over on another planet, Bara Magna, villages had settled around various structures; the rock tribe's looking like a head with a Cave Mouth but the rest unidentifiable.

- In Binary Boy, the second level is essentially the same grassy area as first, but at dusk-time, and so a moon appears on the screen.

- When you answer a certain NPC's questions correctly in Breath of Fire IV, he will point you to a weird rock in quarry nearby.

- Dead Space 3 has the moon itself. It's actually a moon-sized Necromorph called a Brethren Moon or Brother Moon that was forced into sleep mode, but if awakened would go around eating the biospheres off of planets. Isaac manages to destroy it, but for a little bit of Paranoia Fuel, the first letter of each chapter in Dead Space spells out BROTHER MOONS ARE AWAKE. Plural. Oh crap. This is confirmed in the Awakened DLC, and the Brethren Moons are already feasting on Earth.

- After a certain Boss Battle in Final Fantasy X, the heroes find themselves in the frozen lake underneath Macalania Temple.

Then the sun sprouts wings and a title fills the entire screen: "THE RADIANCE".
- Jade Empire has a sidequest involving the search for a corrupting demon of hunger called the Cannibal Mother...which ends in a giant cavern with a strange rock formation in the middle of it. Needless to say, it's not a rock formation.

It then proceeds to shoot at you.

- In Portal 2, one of Cave Johnson's "alternate universe" recordings ends with the revelation that the planet you're on is, in fact, Cave Johnson. Cave Johnson is really big in that universe. Spoiler tags really aren't necessary for that, because he couldn't hold in the secret very well either.

- The Adventures of Dr. McNinja #8 parodies the Star Wars line in the Alt Text of one page, and inverts it in the same issue: The moon at Dracula's place (yes, Dracula) really is a moon, it just happens to be Dracula's actual base, and it just so happens that it can fire orbital lasers.
- Parodied in Darths & Droids, where the Death Star was originally designed as a "Peace Moon" to replace Naboo's moon that was destroyed in Episode I's war. The name stuck even as the plans were altered to make it a weapon, leading to this exchange:
Han Solo: He's headed for that big space station.
Obi-wan: That's no space station. It's...the Peace Moon!
- Girl Genius: That's not a cloud.
- The Little Trashmaid: Inverted. After being shown The Little Mermaid (1989) on Disney+, Tidy believes that a large black-and-purple octopus-shaped heap of trash is actually Ursula, and has an intense one-sided off-screen fight with it.
- The Order of the Stick:
- The members of the Order of the Stick learned a while back that their planet is actually a prison for an Eldritch Abomination, and are trying to keep it locked away. This is both to prevent its escape, and to ensure the gods don't tear down their old prison to replace it with a stronger one.
- Minrah and Durkon, when reaching the afterlife, believe at first to be walking on some Fluffy Cloud Heaven with a dark sky, and spot a tower in the distance. Except said tower is actually the god Thor's leg, the fluffy ground is the fur of his boot, and the sky background is his cape. Yes, the Stickverse gods are huge compared to mortals. (And then Thor shrinks down to talk to them, and it turns out the location they're in is still on a cloud with a darkish sky, just slightly differently drawn.)
- In this strip of Gone with the Blastwave, couple of soldiers invoke this trope when one of them can't believe they are on the surface of the moon after walking there from inside a Space Station that was nowhere near the moon. Also this moon suspiciously has a ceiling.
- In a strip from Ryotiras, two characters find out that the "Moon" they're looking at is actually Earth, which means...they're standing on a giant rubber duck.
- In Schlock Mercenary:
Cikitsaka: We've found a wandering planet that appears to have an ancient artifact inside it. Before you ask how old "ancient" is, let me paint a clearer picture: We suspect that what we actually found is a wandering ancient artifact that has accumulated enough debris to make it look like a planet.
- The Oafan space station Eina-Afa - a cylinder big enough to contain Mars, with room to spare - has Tagon quoting the trope outright.
Tagon: I thought a thing orbiting a thing orbiting a star was called a moon, but in this case[,] that's no moon.
Tagon: It's a space station.
- Also, Oisri from the previous arc counts.
- The Oafan space station Eina-Afa - a cylinder big enough to contain Mars, with room to spare - has Tagon quoting the trope outright.
- The line is parodied in Sequential Art.
- Sluggy Freelance parodies this in a Star Wars Shout-Out in this strip. Basically, Torg refers to a "moon-sized thing with teeth" but someone corrects him anyway that it's no moon, it's a thing with teeth.
- In this strip of Starslip a character wants to land on a "moon" when another points out that it has a seam running down the middle.
- Speaking of seams, see Iapetus, below.
- In Tower of God, the characters travelling on the Hell Train arrive on the Floor of Death, the only floor of the Tower not ruled by one of the nearly all-powerful creatures known as Administrators (or Guardians), because it was killed by an even more powerful being. After they have stared at the hostile landscape of thorny cliffs and red water for a while, their guide tells them that they're looking at the hide and blood of the Administrator's body, which covers the actual floor.
- The Unspeakable Vault (of Doom) demonstrates the worst-case scenario: landing on an "island" that's actually a napping Eldritch Abomination.
- Kill Six Billion Demons: In "Wielder of Names", Juggernaught Star takes White Chain (both are angels) to a place with a backdrop that appears to be a cliff or something. It's not shown in focus in the comic, and White Chain surely doesn't suspect it's anything special. Soon, though, it's revealed to be the giant wing of Metatron, the greatest of angels, who was thought to be long dead but is in fact still marginally clinging to life.
- /m/ wrote a Science Fantasy universe where the local solar system's sun was surrounded by a giant Dyson Ring that was actually a large dragon that bit itself in the tail. This was the largest example of this trope at the time of writing. /m/ does not think small.
- In Orion's Arm the brains of the ruling transhuman intelligences start at the size of the moon and go all the way up to being the size of the star Betelgeuse, which is larger than the orbit of Jupiter.
- SCP Foundation:
- SCP-507 (who randomly teleports to alternate universes) once found himself at the mouth of a cave, looking at a desert planet baked by its two large suns. Then the "suns" blinked and looked away...
- The Foundation is also suppressing knowledge of SCP-169, a sea arthropod that is so large that its protrusions above the waterline were mistaken for an archipelago of islands, and which was responsible for the Bloop.
- SCP--2362. It used to be Pluto...until a moon sized jellyfish hatched out of it.
- SCP-5005 is a town located on a strange landmass floating in the void far outside of the multiverse with the only light source being a glowing orb hanging from a tall spire. Several theories have been made about how such a place could exist but investigating it is difficult if not suicidal because matter that strays too far outside of the light disintegrates. The long-term residents of the town don't care about why the place exists but many visitors end up going mad and dying trying to figure it out. In a Cruel Twist Ending for someone who actually succeeded at discovering the truth at the cost of their own life, it turns out the truth is the least meaningful of the theories. The landmass is the slowly decaying corpse of an oversized anglerfish-like creature.
- In Adventure Time, the Ice King washes up on a random island only to discover that it's a giant island woman named Senorita. She turns out to be a lot nicer than most of the examples on this page.
- In another episode, Finn has a dramatic musical moment on top of a grassy mountain. The mountain then gets up & turns out to be the cyclops Finn was looking for at the beginning of the episode so he could use his tears to heal his broken leg. Finn no longer cares about that but the cyclops tries to kill him anyway because he doesn't believe him.
- Avatar: The Last Airbender:
- On the eve of the climax, Aang leaves his friends' camp and wanders to the shore, where he sees an island. When he visits it, true to form, the island isn't there in the morning. The island is a giant Lionturtle, that actually turns out to be pretty important to the plot.
- The Foggy Swamp is located on the roots of an enormous, sentient banyan tree.
- In Code Lyoko Season 4, episode "Maiden Voyage", the heroes' virtual ship is lost in the Digital Sea, where it is attracted by a Replika which they think to be Lyoko at first. The scene is a direct Shout-Out to the Trope Namer, with the Replika looking like a giant metallic sphere and Aelita saying "That's not Lyoko!"
- Played with in Codename: Kids Next Door in "Operation C.A.K.E.D.-F.I.V.E" as part of a Star Wars shout-out. Numbuh 86 and 19th Century are heading to the Moon Base when an alarm alerted them of approaching the base. 86 mentions that they shouldn't be there yet and looks up, sees Father's giant ice cream cake and says, "That's no moon!"
- In an early episode of Dora the Explorer, Dora and Boots go to search for the Big Red Chicken. According to legend, the chicken lives on the Big Red Hill. No points for guessing what the Big Red Hill really is.
- One episode of Dragon Tales had the gang lose the ball that they were playing with to the depths of a cave that was nearby. All of them went in to search for it, but Cassie nervously hung back when she noticed that the floor of the cave was oddly squishy. Turned out to be the mouth of a giant sleeping dinosaur thing, which soon woke up and swallowed everyone....
- Family Guy: A somewhat smaller example than the rest, but quite large for its scale — in one episode, Peter is in a sauna with Chris, when Peter notices..."Hey, that's not your leg!" The rest of the episode is about Peter trying to deal with penis envy (or something more like "penis shame").
- Gravity Falls: The "Dipper's Guide to the Unexplained" short "The Tooth" deals with Dipper trying to find the source of a giant tooth he found on the shores of Lake Gravity Falls. A cashier tells them to run if they see bubbles on the lake. They see bubbles near an island, at which point Mabel proceeds to paddle away. Turns out the giant tooth came from the island, which is a monster that rises out of the water and tries to eat anyone who gets too close.
- Justice League: In "The Savage Time", John Stewart (who'd lost his ring) noted to the soldiers he was attached to that the hill they were standing on did not exist in the map they have. It turned out to be Vandal Savage's hanger for his advanced jet bombers that would be used to invade the USA.
- In Roughnecks: Starship Troopers Chronicles, the Ice Bug is an asteroid-sized space creature that hibernates for interstellar travel. One of the movies had a "Godbug" which could supposedly devour a planet.
- The Simpsons: Sort of a Lampshade Hanging in an episode. A runaway Sacagawea (Lisa) stops to weep on a rock, saying "O warm, fuzzy rock, you're my only friend!" The warm fuzzy rock is actually a wildcat.
- SpongeBob SquarePants:
- "Sandy, SpongeBob, and the Worm" has Sandy arrogantly going after an "Alaskan Bull Worm" threatening Bikini Bottom. She attacks and ties a knot in what she thinks is the worm before SpongeBob can tell her that it's actually the worm's tongue. What she assumed was a cave was the rest of the worm.
- In "Nature Pants", SpongeBob runs away from Bikini Bottom and Patrick starts chasing him. SpongeBob runs behind a supposedly big rock to hide from him, but the "rock" turns out to be a gigantic snail.
- Played with in "Plankton's Army". Plankton's family comes to help steal the Krabby Patty formula. They surround the Krusty Krab and Mr. Krabs asks "You planted grass?" Then the grass started laughing and reshaping itself into limbs and ears...
- The first season finale of Transformers: Beast Wars uses this. Turns out, when they are finally rid of the giant scary orbital weapon that wasn't a moon, the planet starts to look suspiciously familiar...
Megatron: Idiot! It was never a moon, and it is far from gone!
- In Transformers: Animated, the ship that the Autobots use to come to Earth is revealed to be Omega Supreme, one of the most powerful Autobots. Ratchet is aware of this. The other Autobots are shocked, and the Decepticons have a big Oh, Crap! moment.
- In Transformers: Prime, Earth is actually Unicron in disguise!
- The first season finale of Transformers: Beast Wars uses this. Turns out, when they are finally rid of the giant scary orbital weapon that wasn't a moon, the planet starts to look suspiciously familiar...
- In Shadow Raiders, the planet Remora turns out to be a giant battle station created by the Beast.
- Spoofed in Celebrity Deathmatch, when Bam Margera goes into orbit around the massively fat Don Vito.
- My Little Pony: Friendship Is Magic: In "Three's a Crowd", Twilight and Cadance search for a rare flower on a mountaintop around what they think is a large tree...before realizing that the flower is the tree. They couldn't realize this while climbing up since the top was covered by a cloud.
- In the Phineas and Ferb episode "The Chronicles of Meap":
Phineas: He's headed towards that small cloud!
Ferb: That's no cloud, that's a space station.
Phineas: I've got a good feeling about this!
- In an episode of The Flintstones, Fred and Barney go fishing on a boat in open sea, and they stop on a weird white, seemingly deserted island to eat their lunch. The "island" is actually a giant white whale named Adobe Dick that promptly gets mad and chases them. When they try to escape, it goes underwater and re-emerges to fool them into believing his mouth is a cave to swallow them whole when they try to hide inside.
- The Thunder Cats episode "The Mask of Gorgon" features the Hills of Elfshima, that turn out to be the sleeping form of the gigantic Child of Gorgon, which Lynx-O and Bengali have to defeat by means of unleashing a powerful sonic blast into its gigantic ear from within.
- Scooby-Doo! Mystery Incorporated: Niburu has been casting its' shadow over Crystal Cove more literally than expected when it reveals itself as the seemingly-always full moon in the finale.
- Geologists knew, from certain terrain features such as geysers and hot springs, that there was an inactive volcano somewhere in Yellowstone Park. They searched for the caldera but were unable to find it — until aerial photos revealed that the entire park was the caldera.
- Also, it turns out the Yellowstone supervolcano isn't so inactive after all. It has a major eruption about every million years, give or take a few hundred thousand. The last eruption was 640,000 years ago, and was about 24,000 times stronger than the largest nuclear bomb ever detonated. Another such eruption would likely kill everything within a hundred miles, and even a thousand miles downwind the land would be buried in two meters of ash. This was explored in excruciating detail in the docudrama Supervolcano.
- Another is Siberia. Not in Siberia, Siberia. The last eruption corresponds with the Permian extinction that wiped out most of the species on Earth. And "most of the species on Earth", in this case, means roughly 90%. Among other things, this was the only time in all of Earth's history that insects suffered a mass extinction. That's right, if Siberia erupts again, even the cockroaches wouldn't survive.
- In another park, biologists were finding tendrils (mushrooms' underground part) all over the place, but no mushrooms nearby, so they wondered where they all were. It turned out all those tendrils (kilometer-wide!) belonged to one single mushroom colony, growing inconspicuously near one tree.
- Technically, the mycelium (the network of tendrils) is the main body of the fungus organism. The visible mushrooms are just temporary fruiting bodies.
- A nice inversion: Three years after A New Hope came out, space probe flybys revealed this◊ closeup picture of Mimas, one of Saturn's moons. Kind of Hilarious in Hindsight.
- It's also Pac-Man, apparently. That's no moon, it's a 1980s pop-cultural icon!
- Iapetus, another moon of Saturn, has a light-colored side, a dark-colored side, a straight mountainous seam running along its equator, and a large crater in a certain part of it. You gotta wonder. Then again, most just compare it to a walnut, and call it a day.
- Hashima, an island off the coast of Nagasaki, is often called Gunkanjima (Battleship Island) because the sea wall and the buildings on the island make it look like a battleship. Supposedly, during the Second World War, an American submarine mistook the island for a Japanese battleship and launched torpedos at it.
- There's a forest in Utah that covers 107 acres, with about 47,000 trees....Correction: there's a giant tree in Utah named Pando with about 47,000 stems. Pando is a male tree. This is apparently not as unusual for Quaking Aspen as we'd have suspected — we just never looked all that close at forests before. Pando is also probably 80,000 years old.
- Inverted by a stretch of land off the Gower Peninsula in Wales called the Worm's Head, which bears a striking resemblance to a colossal sea serpent in silhouette◊. Cannae remember whether it's true or not, but apparently it scared off a shipful of Viking raiders, who later got shipwrecked in Swansea Bay.
- David Icke theorized that Earth's Moon is not a moon at all but is rather some sort of organic, hollowed-out planetoid or possibly an ancient spaceship built by Ancient Astronauts.
- A fun exercise for people who live near the shores of the Great Lakes (places like Toronto, Milwaukee, or Chicago) who have friends who live overseas and aren't overly familiar with maps of North America: tell them to look up your town on Google Maps. Their first reaction will be, "Wow, you live really close to the sea." Then they realize that isn't the sea...!
- In 1978, on the flight where he mysteriously disappeared, Australian pilot Frederick Valentich sent a series of radio messages saying that he was being pursued by an unidentified aircraft. His last words?
"It is hovering and it's not an aircraft"
- The enormous Christmas tree pictured here. Oh look, somebody set up a model of a city underneath of it! Wait a minute...what do you mean that's not a model?!
