OK, everything seems normal, but for some reason you can't get your bearings. When you look up... it's an Alien Sky.
Maybe there are two
moons. Perhaps Earth's all-too-familiar moon, the one in all the love songs, is broken into so many pieces it's become a ring of debris around the planet. Or the sky is dominated by an huge gas giant like Jupiter or Saturn, suggesting you are in fact, technically, on
the moon. The sun is a different colour, or has a little and a bigger brother
. The daytime sky is a lovely shade of deep purple. The nighttime sky is empty
. Maybe the sky is simply home to cloudforms that are not of this world... or lifeforms
. Or rocks
Such things serve as an obvious visual means of showing the audience
that the characters are in another world!
Sometimes used to comedic effect when our heroes just won't believe they've left Earth for good, and shrug off all other, often painfully obvious, hints as some kind of Masquerade
("Wow, great special effects! I'm on hidden camera, right?").

Anime & Manga
- Two moons in Zero no Tsukaima, Queen's Blade and Seirei no Moribito.
- A huge, red sun in Now and Then, Here and There.
- In Magical Girl Lyrical Nanoha StrikerS, Midchilda seems to have, conservatively-speaking, at least six Earth-like planets hanging in its sky for no discernible reason. A number of other planets they visited in the previous season also have this unusually populated skyscape.
- Panzer World Galient: Planet Arst, where the action happens, has two moons.
- The Vision of Escaflowne had Earth hanging in the sky.
- The Digital World in Digimon Frontier had three moons.
- The Digital World in Digimon Savers had rocks floating in the sky and it sometimes had electronic textures on it.
- The Tamers era had a digital representation of the earth floating in the sky.
- Digimon Xros Wars had this used, not to show that they were in another world, but that they went from one section of the other world to another section, with the island zone having a pattern in the sky
- Even the original-flavor Digital World of Adventure had a mild version of this. Early on, Joe tries star-gazing to figure out their location, only to realize that none of the constellations match up to what they should be.
- Manabe Johji's Capricorn is set in a Lunar-like alternate dimension in which our Earth is visible in the sky over the moon. The moon is itself a planet with Earth's density and gravity, if not its size.
- A variation: It's not the sky which tells Youko that she's arrived in the world of The Twelve Kingdoms, it's the alien-looking sea. Later in the series, she flies to a palace on a high mountain and discovers there's another (watery) sea above the clouds.
- Similarly, it's the not so much the sky itself in Eureka Seven that looks alien, but the luminescent clouds of light particles that blow across it. The ground's not exactly normal, either, what with the huge chunks of coral-like stuff jutting out of it. Against all odds, though, it turns out to be Earth. Even the protagonists are shocked.
- Tengen Toppa Gurren Lagann played the double moon version during a chapter with the Moon and the Hyper Galaxy Dai-Gurren.
- Darker Than Black has as part of the back story that the normal sky of the Earth disappeared when Hell's Gate opened 10 years ago, taking with it all constructs found above the Stratosphere. Attempts to reclaim space only result in silence from whatever is sent up there. Instead, the stars in the night sky are all artificial and bound to a particular contractor, blinking as the contractor uses its power and falling from the sky when the contractor dies. The moon has disappeared and the sun is altered; every few years, the sunspots move around so much that the sun looks like a giant glowing eye for a while.
- Simoun takes place on a planet in a binary star system, which accounts for the Fashionable Asymmetry in the clothes design of the Sybillae.
- In Dragon Ball Z, Namek has a green sky (and blue grass), and three suns that illuminate the planet's entire surface at all times. And lollipop-shaped trees.
- The Sacred World of the Kais is always well-lit despite not appearing to have a sun, instead having hundreds upon hundreds of purplish spherical moons around it. Then again, it is in the Afterlife.
- In Stellvia of the Universe space, and thus the night sky, is green now. This is justified in that Earth is in a part of space still suffering the effects of the supernova explosion of the star Hydrus Beta ( which almost destroyed human civilisation ) and so occupies what seems to be a nebula. Space changes colour again later on.
- Cowboy Bebop has a cracked moon in Earth's sky and tons of debris that rains down upon the Earth on a daily basis. Few people live there, opting instead for other, terraformed bodies in the Solar System with even weirder views of the heavens.
- Speaking of space westerns, Trigun appeared to take place on wild west Earth at the beginning, but the twin suns, five moons, and purple night sky caused by three or more moons shining at one time is a tipoff to the contrary...along with all those alien-looking people and weaponry...and those giant Plant systems.
- Allison and Lillia has, in addition to its Alien Geography, a moon which is much closer to the Earth, orbiting every eight days and producing spectacular solar eclipses on a disturbingly frequent basis. Strangely, however, calendar months are still roughly 30 days long...
- In Trinity Blood, Earth has two moons: the normal moon, and a new "Vampire Moon", which is the colony ship the Methuselah used to travel to Mars and back.
- End of Evangelion ends up with Earth surrounded by reddish ring made of blood. The sky looks even worse in the middle of the film.
- Sentou Yousei Yukikaze has a hard version of simply making the atmosphere of Fairy green-tinged, with a double star system as its sun.
- In the Sonic the Hedgehog OVA, a large planet with Saturn-like rings is visible in the sky over the North Pole.
- In Star Ocean EX, Expel, a medieval Earth-like planet where the action takes place, has two moons, one glowing blue and the other glowing red.
- This is a major plot point in Brigadoon: Marin and Melan. Because of the impending mutual collapse of the two worlds, Brigadoon is visible in Earth's sky for the entire series, and vice versa. (On Submaton Color you can see both worlds at the same time.)
- In Last Exile: Fam, the Silver Wing, Earth has 6 moons. Not all of them are actually moons.
- Used in Avenger to show viewers that it is really Mars where the action takes places.
- In Saint Beast, while the sky in Heaven may not make much sense, it's definitely very beautiful.
- Mostly averted in ARIA. Despite that the series takes place on Mars, renamed Aqua, the sky is no different from our, and very little is said or seen of the two moons. One episode mentions them while the characters are moon viewing, but otherwise the Scenery Porn focuses on just about everything else.
- The final scene of Sakasama no Patema has Patema and Age/Eiji venture off to explore what's left of the surface world - which includes a shot of what appears to be the planet Saturn, where the Moon should be. In the broad light of day!
- The setting of the Elfquest comics also has two moons — and is called the World of Two Moons, in honor of the fact.
- The planet Elekton in The Trigan Empire has two moons and two suns.
- Subverted in the world-hopping arc of Mystic, when Giselle initially assumes herself to be lost in a jungle in Shaman Guild territory. She reaches a clearing, looks up, and is startled to see that there's only one moon. However, it's the (strangely human) locals' reaction to her magic that finally convinces her that she's not on Ciress any more.
- In Justice League: Generation Lost Captain Atom is thrown across time for a couple of days due to absorbing immense amounts of energy. At first he thinks he's in the past as he stays with a rural family who lack modern technology. Once the night falls, he notices that half of the moon has been blown apart.
- In With Strings Attached, at the beginning, when Paul is awakened by John and discovers they're outdoors in a field somewhere, he angrily assumes John spirited him away, despite John's vehement and frightened denials. Trying to find a hidden camera crew, he notes that the full moon is setting over the nearby forest. Then, on the beach, he does a double take when he sees the crescent moon over the ocean... and then he knows John wasn't responsible for this predicament at all.
- Star Wars has Luke framed against a simple but gorgeous twin sunset in the first movie. It's the first shot in the film to really drive home the point that this isn't Earth, and succeeds spectacularly, despite being one of the film's simplest effects: it's just a double exposure of a real sunset. It also features the rebel base on an Earth-like moon orbiting a giant, red gas-planet.
- The 2002 remake of The Time Machine has a cracked moon and debris field circling the Earth, the product of the man-made disaster that prompted the Morlock/Eloi Earth in this version.
- The Dark Crystal makes a big deal out of the Great Conjunction of the Triple Sun, during which time huge world-changing events are known to occur.
- The Quiet Earth (see the illustration) ends with Zac on an alien world, or radically changed Earth, immediately obvious because of the weird clouds and ringed planet rising in the sky.
- The unnamed planet in Pitch Black has three suns, which causes it to be constantly daytime, except once every 22 years, when there is a triple eclipse. The several other celestial bodies in the system (moons and planets, some with rings) that are responsible for the eclipse are also visually impressive.
- The world Krull rotated around two suns. There were no double-shadows, we never saw the sky enough to find both suns, and there was no plot-significant reason for there being two suns. It was just cool.
- The Reveal in Galaxy Quest, when the huge dome opens and Taggart finally realizes where he really is.
- In the theatrical showing, there was another level to this. The opening minutes, where the 'clip' of Galaxy Quest is played, was in 4:3. When this ended, the aspect ratio pulled back to "standard" 1.85:1. When the doors open the ratio was again increased, this time to 2.35:1. The DVD ignores this.
- Vanilla Sky. The sky is the same milky orange with white clouds because it was David's mother's favorite time of day, so his subconscious made it that color all the time. The film also toys with the perspectives of light, as in certain scenes the sunlight illuminates the set from impossible angles.
- Stargate (the movie) showed an alien sky on the planet Abydos with three full moons visible at the same time. This turned out to be the basis for the planet's point-of-origin symbol on the Stargate's dialling ring.
- The 1980 version of Flash Gordon features an immense sky full of vivid, multi-colored clouds visibly surging and roiling. The "sky" may in fact be more akin to a nebula, as continent-sized "moons" are seen to float in it. Its relationship to the "Sea of Fire" the heroes fly through to reach Mongo is unclear.
- Mongo probably orbits a companion star that spins around a red giant that has become a planetary nebula. It looks similar to the Helix Planetary Nebula when Zarkov's ship approaches it prior to reaching the Sea of Fire (the red giant's corona).
- Mongo may be Jupiter; much surface area, with many moons. The current view of the Solar System at the time the strips were written might support this. Perhaps why the sky is a 'sea of air' filled with colourful clouds, even in the strips.
- In Coneheads, the Conehead's home planet has three moons. The rare event of all 3 lining up perfectly in the night sky is commemorated as a holy day.
- Highlander II: The Quickening is set in the future, where the sky has this reddish cloudy color.
- The "sky" in The Truman Show has an artificial quality, as it's painted/projected against the interior of an enormous dome and the moon is stationary in the same place, day or night. The "moon" is really where the mysterious director of the Truman Show resides and watches over Truman's life, and can in emergencies be used as a giant searchlight.
- In Avatar, the gas giant Pandora orbits, and its sibling moons, are prominent in its sky - as is, in one scene, either Alpha Centauri B or the drive flame of an RDA starship.
- In Predators, the protagonists go "we're not on Earth anymore" when at a certain point they see a sky with at least two gas giants.
- The point of origin for the film/Pacific Rim kaiju seems to have a black hole for a sun.
- In John Carter, Mars has two moons. Which look nothing like Mars's actual moons.
- Hunter Prey: A big red planet hangs overhead.
- Damnation Alley: A symptom of the recently-fought nuclear war.
- The wreckage of the destroyed Moon in Oblivion (2013).
- At the end of Cloud Atlas, this trope appears to show that an aging Zachry is narrating his tale from one of the off-world colonies long after being rescued.
- In Contact, the aliens create a setting with a fantastic skyline (including a worm hole) based on the drawing Ellie drew as a child.
- Jennifer Fallon's Second Sons series takes place on a planet with two suns. The driving event of the story is one sun eclipsing the other for a period of many years, allowing a corrupt cult to take over the world.
- Malacandra, otherwise known as Mars, in C. S. Lewis's Space Trilogy has giant chunks of pink coral for clouds, set in an electric blue sky. It turns out the "clouds" are the Martian surface and the bulk of the story takes place in deep, narrow canals.
- Due to Perelandra/Venus's thick atmosphere, the Perelandran/Venerean sky is solid gold during the day and pitch black at night.
- Similarly, in The Magician's Nephew in The Chronicles of Narnia, the sky of Charn is very dark even in daytime, and the children see a second, smaller star (implied to be a white dwarf) close to the red giant that is the world's primary star.
- The novelizations of Magic: The Gathering's Mirrodin block had the four moons (corresponding to four of the five colours of mana) as its main plot element. The third set in the block, Fifth Dawn, is about what you'd expect. The better known world Dominaria has two moons, the Mist Moon and the Glimmer Moon or Null Moon which turns out to be an artificial construct storing mana and is destroyed during the climax of the Wheatherlight saga.
- Isaac Asimov's short story (and later, novel) Nightfall takes place on Lagash, a planet with six (!) suns and one moon. This is a major plot point, as when the moon eclipses the sole sun remaining on one side of the planet (after the others have all set), which happens every 2049 local years, Lagash's people go insane and destroy their civilization. It wasn't just the darkness that drove the people insane; it was all the stars in it. Their astronomers had theorized that there might be other star systems, as many as twenty or even a hundred - a number which another character whistles at, commenting that it would reduce their world to insignificance. Earth's sky would be enough of a shock, but Lagash is close to the center of the Galaxy, and the splendor of a star-packed sky - the sudden revelation of how vast the universe really is, and how indescribably tiny they are by comparison - is enough to crush even the most "prepared" mind.
- The Dragonlance novels are set in Krynn, a planet which initially has three moons. Each one has a color, the larger one is white, the medium one is red and the smaller one is black, and also invisible on regular circumstances. Sometimes the moons align and make a "eye" in the sky.
- Used to truly horrible effect in the Legends trilogy. Normally, the constellations in Krynn's sky are many, one for each god. When Caramon steps into the future, the sky is empty of stars, save only for a single constellation- an hourglass signifying Raistlin, his twin brother. Every other god had been slain.
- The Andalite Chronicles, a prequel to Animorphs, has a piece of Phlebotinum create a small universe based on the memories of the main characters. The sky is a patchwork of bright blue with fluffy clouds (Loren's memories of Earth), deep red (Elfangor's memories of the Andalite homeworld), and sickly green with lots of lightning (Esplin 9466's memories of the Yeerk homeworld, problems with that notwithstanding).
- Near the end of Monica Hughes's Invitation To The Game, the small tribe of main characters believes they're still in a virtual-reality world until they realize that they can see the Milky Way from outside it, and there's no moon.
- Darkover has four moons and a dark red sun, colloquially known as "the bloody sun."
- Dragaera's sky is covered with a reddish-orange overcast as a side effect of using sorcery, making the light dimmer during the day but also less dark at night. When Vlad Taltos ventures outside the Empire, he's taken off guard by the blinding days and pitch-black nights. In Issola, he visits an alternate dimension where the sky is very different from normal.
- Played with in The Chronicles of Amber; sky color is one of the ways to tell where you are when walking between worlds.
- In the Warworld series, the Alien Sky is an important plot point, as the moon Haven has a day/night cycle 87 hours long, so having a heat-radiating Brown Dwarf in the sky can mean the difference between freezing to death and merely losing a few toes.
- Another CoDominium setting is the twin planets of New Washington and Franklin, which are tide-locked so that each sits unmoving in the same part of the sky every day when seen from the surface of the other.
- In the Riverworld series, the sky is moonless, but has brighter stars than Earth, including some still visible in the daytime.
- Larry Niven
- Ringworld: the Ringworld sky is dominated by the Ring, and "night" is produced by the Shadow Squares.
- The Integral Trees is, if anything, more bizarre. The "planet" is the sky. The Ring is a (mostly) gas torus from a supermassive gas giant in close orbit around a neutron star, which is a binary with a yellow dwarf.
- In A World Out of Time, Niven gives us an Earth that has been moved to orbit Jupiter, because a planet was dropped into the Sun during an interstellar war, making Earth's former orbit uninhabitably hot.
- The Flying Sorcerers, which he co-wrote with David Gerrold, is set on a planet with two suns (a big red one and small blue one that orbits it) and no less than eleven moons ("...three body formation makes capture easy..."), as a plot point. The system also has no other planets and is inside a giant dust cloud, so there are no visible stars, although the formations of the moons are observed in a similar way to how we observe constellations.
- Star Wars Expanded Universe:
- Used to drive the point home as to just how powerful the Yuuzhan Vong are - they take one of Coruscant's moons and shatter it, turning it into a planetary ring. This ring and another of the planet's moons were thrown out of orbit when the living (and hyperspace capable) planet Zonama Sekot entered the system in the last NJO book.
- In other novels sky colors are occasionally mentioned. Not a color as such, but it's said that Coruscant, with all that pollution, has an unbelievably beautiful sunset.
- Gene Wolfe's Book of the New Sun is set so far into Earth's future, the terraformed Moon is covered in green forests, and the sun has dimmed to the point that stars are visible in the daytime.
- Dune: Arrakis has two moons. Similar to the Man In The Moon, people see pictures in both of them, in this case a mouse and a fist.
- In the novel Under Alien Stars, the title actually refers to the alien character in the book (which involves Earth becoming a backwater world between two empires who are at war), since the book is set within Earth's gravity well. That is, it is Earth's sky that is alien.
- Against a Dark Background by Iain M. Banks is set within a lone solar system that is outside a galaxy. This is revealed two-thirds through the book, but hinted at a several points, notably in night-time scenes where starlight is not mentioned but "junklight" (light reflected from satellites & space junk in orbit above) is.
- Pern has two moons—Belior is the larger one, Timor is the smaller one. Since the dragonriders often use the moons' positions as coordinates for going between, it's likely that they can be seen during the daytime. However, the plot-important aspect of the sky is the Red Star, which starts raining Thread onto the planet once it gets closest to the sun.
- In Dan Abnett's Gaunt's Ghosts novel His Last Command, when Mkoll and Maggs have gone through a Chaos warp gate — the stars are all wrong, and there are massive stone blocks floating in the air.
- In Graham McNeill's Warhammer 40,000 Ultramarines novel Dead Sky Black Sun, not only is the sun black, it never moves.
- Perry Rhodan had for Earth or alternate main mankind worlds:
- A failed teleport put Earth and Moon in interstellar space, with "atomic suns" in orbit providing light and heat, then was moved into a system with a red star.
- During Earth's absence, the main human world was Gaea, around a normal star, but inside a dark nebula.
- The newest "main" human worlds are in the Stardust system, with the 3rd to 6th planet habitable, the main (4th) having 2 moons, the 5th 4 moons, several gas giants further out in the system - and the system is in a globular cluster so it only really gets dark when it's cloudy.
- The planet Krikkit from Life, the Universe and Everything is an example of an alien lack of sky, there are no visible stars or moons because the entire planet is surrounded by a dust cloud. This has an effect on the populace somewhat reminiscent of Nightfall (see above). When a spaceship crashes into the planet, the locals hear it coming and it doesn't even occur to them to look up, because there's nothing ever there. The idea that there is something other than their world is an utterly alien one, and when the repair the ship and escape their atmosphere for the first time, allowing them to gaze upon the universe, they come to an inevitable conclusion: "It'll have to go."
- In The Pendragon Adventure, the territory Denduron has three suns. Eelong has a "sun belt," a thin line of sunlight that crosses the entire sky.
- In The Wheel of Time, the prison of the Dark One is accessed through a simple tunnel into the mountain Shayol Ghul but the view from the inside is "a sky that was not the sky of" the normal world, with "wildly striated clouds streaking by as though driven by the greatest winds the world had ever seen." Given the other atmospherics and the fact that the Pit of Doom is outside the universe, this may just be to freak visitors out.
- Inverted in the Diane Duane Star Trek novel Spock's World, in which Sarek finds Earth's tiny, silvery moon a bizarre spectacle that helps him come to terms with the idea that he's really on another planet.
- One Cthulhu Mythos story involved the World Of 7 Suns which, as its name suggests, is orbited by seven artificial suns.
- Godspeaker Trilogy takes place on a world with two moons, a large and a small one. The Mijaki call these "the godmoon and his wife". Whether the other cultures of the world have their own names for the moons is never mentioned.
- The Fantasy Counterpart Culture novels of Guy Gavriel Kay (like Tigana) take place on a world with two moons, one blue and one white.
- The appearance of the first clouds to appear over Fourecks for thousands of years invoked this trope in The Last Continent for some local Discworld wizards, who'd never seen such a thing before.
- Lisanne Norman's Sholan Alliance series puts the action on the distant planet of Shola, which has two moons. One of which is missing a large chunk.
- Mars' twin moons Deimos and Phobos feature prominently in the descriptions of Barsoom's night sky in the John Carter of Mars novels.
- The planet Erna of the Coldfire Trilogy has three moons—Prima, Domina, and Casca.
- In Clive Barker's young adult fantasy book Abarat, it's seeing the unfamiliar stars in the sky that really hits home for Candy Quackenbush that she's in another world.
- The sky/skies of the Abarat are an odd example: each island has its own set of stars and its own sun and/or moon, and each island is permanently in a different hour of the day. The straightest example would be the sky over the The Twenty-Fifth Hour, The Time Out Of Time, where it's always night but the colour of the sky is inverted: the sky shines white, while the stars are points of blackness.
- The Leeshore by Robert Reed - The sun never shines on the surface on the planet, as the entire planet is encased in a sphere of biological gas bags, effectively creating a forest a mile above the sea.
- The Stormlight Archive - Roshar has three moons, Nomon, the largest one is bluish white, the middle moon Mishim is green, and Salas is the smallest and is purple.
- J. R. R. Tolkien made a point of describing a very familiar sky over Middle-Earth, right down to the constellations Menelmacar (the Swordsman of the Sky, known to us as Orion) and Valacirca (the Sickle of the Valar, or our Big Dipper). But if you dig in and read the creation lore in The Silmarillion, you find out that the Sun is a piece of golden fruit and the Moon is a silver flower, plucked from the branches of the light-bearing trees Laurelin and Telperion before they died.
- The Books of Ember: The sky is the same empty blackness as everything outside the City. This trope is later inverted when the people of Ember are surprised to discover that the real sky is blue.
- One of Jack Vance's Allastor stories was set on the planet Marune, which had four suns. The people of Marune have no concept of "day" or "night", but there are set phases of time depending on which suns are in the sky, explained in a chart at the beginning of the book. They prefer to do different things and adopt different moods depending on these phases. During Mirk, when none of the suns are in the sky...well, you'd better lock the door.
- Since the stories are set in a Globular Star Cluster, stars are visible during the day on every planet.
- In the Hyperion Cantos, it's mentioned that several planets have odd sky colours: Renaissance Vector has bronze skies, Nordholm has green, etc.
- In the Illium duology by the same author, Earth in the 40th century is orbited horizontally and vertically by a pair of huge artificial rings where the Posthumans live. Apparently. Somehow.
- The Supernaturalist: Sunsets (at least in Sattelite City) can be any colour, depending on what chemicals are in the atmosphere at the time.
- In Interworld, a world briefly visited by Joey and Jay has no sun, the light comes from the sky itself which is a mess of swirling colours. Despite being extremely bright, the temperature is actually fairly cool. Joey also mentions that the sky somehow feels too low, like it's a ceiling directly above them. But then again, that was a fringe world near the In-Between, so that sort of thing is to be expected.
- The Golden Witchbreed is a minor example: the planet Orthe is close to the galactic core, so stars are visible during the day.
- A Voyage To Arcturus: The planet Tormance has two suns. The natives of Tormance can see the unique radiation emitted from the suns that humans can't, in colours like "jale" and "ulfire".
- The Night Land is a simple but terrifying example: There is no sun.
- In Charles Stross's Missile Gap, the Earth is mysteriously transported outside the (strangely red-shifted) galaxy, which appears to be under the control of a Type III Civilization. Oh, and Earth is a flat disk now.
- In Doom, the aliens have "reworked" Earth's sky to their liking, which has the benefit of nullifying the fallout from the nuclear war.
- In Geoph Essex's Lovely Assistant, the sky of Wonderland (the world on the other side of the mirror that Jenny and the other reapers can travel to) is two kinds of alien skies in one: during the day, it's a weird, sketchy, abstract sepia-toned sky with jerkily moving clouds (most of Wonderland is kind of like that); at night, it's described like some kind of wildly colorful Jackson Pollock painting. The first time Jenny sees a sunset in Wonderland blows her mind.
- In The Lost Regiment, the first indication that they are no longer on Earth is the lack of familiar constellations and a strange wheel-shaped galaxy featured prominently in the night sky.
- The as yet unnamed world in Daybreak On Hyperion has something less of a moon and something that comes across more as a companion planet. Not many details are given, only that its large and purple.
Live Action TV
- The Sliders episode "State Of The A.R.T." changed the color of the sky to lilac. The Ridiculously Human Robot gives it a Handwave about pollution particles— not one that makes scientific sense, but at least it was acknowledged.
- Space: 1999 actually takes place on the moon after it's been blasted out of Earth orbit and the solar system.
- Doctor Who: Pick an alien planet, it's there.
- The Time Lord homeworld Gallifrey is perhaps the most well-known example with its fabled "burnt orange sky", although the Doctor never arrives there at random (and it isn't shown on-screen much at all).
- An early example was the planet Vortis, in "The Web Planet", which had an atmosphere so thin that the stars (and multiple moons) were visible during the day.
- During the eighties, a particular new postproduction technique resulted in a minor run of planets with colored skies, including Thoros Beta in "Mindwarp" (teal) and the unnamed planet in "Survival" (pink).
- A story arc in the eighteenth season upped the ante with a trip to the pocket universe E-Space - where, of course, all the planets had a particular sort of alien sky
- Only at night - space was green in that universe (and since it was later established that inter-universe portals were built to drain off entropy, entropy is green).
- The planet Krop Tor in "The Impossible Planet" had a large black hole in the sky, as well as hurricanes created by whatever said black hole is currently consuming.
- In the year 200,000 Earth is allegedly orbited by four artificial moons, although we never see them.
- In "Silence in the Library" and "Forest of the Dead", the Library has a massive moon taking up most of the sky, which is actually a "doctor moon", a failsafe for the computer core that helped the core when the core forgot she was carrying the minds of 4000 people.
- In "The Stolen Earth", Earth is transported by the Daleks to the Medusa Cascade, where the 26 other stolen planets are clearly visible in the sky against the background of a greenish-yellow nebula.
- Not exactly the sky, but according to the Expanded Universe, in the universe that existed before ours the void of space was pink and planets were toroidal. In the universe that will exist after this one, space is also pink, and filled with green stars that shoot out bolts of green energy and are connected by clouds of algae. Yeah.
- Pylea in Angel has two suns, not that we see either more than once. Conveniently for any vampires present, neither are of the undead-frying variety.
- The Land of the Lost has three moons (and sometimes two suns), but given what's learned about the Land during the series, they may not be exactly... real.
- Planet Hell (the "planetary surface" soundstage) from Star Trek: The Original Series, which always had a different-colored backdrop. I mean, sky.
- And the "demon-class" planet, which had both Alien Sky and Alien ground.
- An egregious example is when Vulcan was seen in Star Trek: The Motion Picture with two really big moons in the sky, even though it had previously been said that Vulcan doesn't have any moons. A Fan Wank Retcon turned these into a sister planet with its own moon ... And then the eleventh movie actually put characters and a starbase on the sister planet so one of them could watch Vulcan get destroyed in a flashback.
- The planet Vulcan is supposed to have a red sky, and no moon - though an animated episode shows a huge disk hanging the sky, usually explained as a twin planet of some kind.
- Stargate SG-1 loves putting many moons and big moons into an alien sky - probably because nine-tenths of the planets look like British Columbia, so you have to show variation somehow. The trend started in the Stargate film, where Abydos has three moons. This trope was used quite well in any episode where Muggles were invited through the gate; they'd say the planet looks just like earth until either they encounter alien technology or a cast member tells them to look up... at the gas giant or pair of moons in the sky.
- Stargate Atlantis did this once to its own characters. Technically, everything's alien on Lantea, but for the 'Lanteans, the Pegasus night sky is familiar—just part of what makes Atlantis home. When the city leaves Lantea and settles on a new planet at the beginning of season four, two moons hanging over the city let the expedition (and all of us viewers) know that things have changed...new sky, new world, new battle. It's a surprisingly moving, alien moment for a series that takes place in an entirely different galaxy to begin with.
- Firefly does this all the time, as the series is set in a solar system with lots of gas giants and habitable moons. The "first episode" features, in its first scene a celestial object hanging in the sky that you really wouldn't want to see on Earth, because it would mean the moon had suddenly and drastically reduced the distance between itself and Earth and altered its surface features.
- The solar system apparently has five suns (white, brown, red, black, and blue) that orbit around each other, each with their own planetary system, but despite them being close enough together to be the in the same system, you never see more than one in the sky at once.
- Power Rangers often depicts alien planets as generic rocky wastelands... but with a color filter over the camera so you know it's definitely not Earth. The Earth's moon (which has a breathable atmosphere, by the way, ever since the first season), has a distinct blue colour, while the hot planet Kalderon has a red atmosphere, etc.
- Done on Earth in Power Rangers RPM, to show just how much damage Venjix has caused. Outside of the Domed Hometown of Corinth, which projects blue skies onto the underside of the dome, the world is covered with a yellow filter to suggest yellow toxic clouds, high radiation levels, and storms of dust.
- The skies of Arrakis in the miniseries Dune deserve a special mention because of the final shot. The hero and his new wife are depicted silhouetted dramatically against a sky which has two moons - in different phases. The creators were going for Alien Sky, and ended up with something way more alien than they were hoping for. Anyone else see a problem here?
- Well, if two moons are at different points in the sky, then the viewing and lighting angles would be different, and the moons would be in different phases. For example, if the sun has just set in the "west", one moon is in the western part of the sky, and another moon is in the eastern part of the sky, the first moon would be a crescent while the second would be more gibbous. The problem with the scene at the end of the Dune miniseries is that the moons are almost in the exact same position in the sky and are still in significantly different phases.
- The David Lynch Dune movie had a colour process where the film shot 'on different worlds' was processed to give a different colour palette; Gold for Kaitain, Green for Caladan, etc.
- In the Tin Man miniseries, when DG first wakes up in the O.Z., she finds herself in a huge forest with two suns in the sky, just to make it clear that (all together now) she's not in Kansas anymore.
- In the music video for The Sword's "Fire Lance of the Ancient Hyperzephyrians", the moon is cracked during a global nuclear war. This corresponds to the lyrics, "Within a shattered planet, beneath a broken moon."
- Surely one of the most iconic examples in music is the video for David Bowie's Ashes to Ashes, in which the sky is black.
- Tom Petty & The Heartbreakers referenced the Damnation Alley sky effects in the Post-Apocalypse themed video for "You Got Lucky".
- According to Filipino mythology, at the beginning of creation, there were seven moons in the sky. The reason why only one is left is that the bakunawa, a massive sea serpent, devoured the other six one by one until Bathala (the androgynous omnipotent creator of everything) punished him severely.
- Similarly, in Chinese Mythology, there were ten suns. They took turns being the sole sun day after day, until they got fed up and rose all at once. This prompted the archer Yu to shoot and kill nine of them, leaving a single sun left.
- Many Dungeons & Dragons settings have multiple moons.
- Greyhawk has two moons.
- Dragonlance has three morally-aligned moons — Solitari (good, white), Lunitari (neutral, red), and Nuitari (evil, black) — but only so long as the gods are around.
- Also, they have a constellation for each of the gods, which vanish from the sky when their god is wandering about on Krynn.
- Eberron has a whopping twelve moons, and it is said that there was once a thirteenth. To top it off, it also has a ring composed of dragonshards.
- Toril (Forgotten Realms) while only having one moon (Selūne), has visibly trailing behind it a string of asteroids (called Selūne's Tears). Plus, it's also worshipped as a goddess. Or seen as a personification of goddess. It's complicated.
- And if you roam the Realmspace, Selūne is inhabited, but they think entire Toril wants to conquer them so entire visible lifeless surface is an impenetrable illusory disguise woven by a goddess (and not the same goddess). But then, for Spelljammer it's not too weird.
- A late 3.5 sourcebook suggested the Tears may be a result of what sounds somewhat like a Giant Draconic Ground-to-Space Fantasy Death Ray missing its intended target (a certain comet) and hitting Selūne instead (which may explain why the Selūnites regard Toril as they do...).
- The Iron Kingdoms setting uses three moons, on very different orbital planes. It is mentioned that the interplay between the moons causes violent and unpredictable tidal effects and maritime weather.
- Wilderlands of High Fantasy features a ring of asteroids in the sky, which change colour every few hundred years.
- Mystara has two moons, one of which is invisible, the other of which is home to the gods.
- Different Clusters within the Ravenloft setting may have different constellations, and specific domains' skies may differ in other ways. Bluetspur's sun never rises, but traces a path just beneath the domain's mountainous horizon; the Nocturnal Sea's skies are always overcast.
- In Dragon Mech the moon has been pulled closer to the world, such that giant rocks (and occasional creatures) are raining down from it, and thus takes up about a third of the sky in most of the art.
- In Elder Evils, the arrival or awakening of an Elder Evil is preceded by a sign. Among the many possible signs provided is Alien Skies.
- Not to mention the weird skies in many of the Outer Planes, which might include floating mountains (Ysgard) multiple huge moonlike spheres which are actually other layers of the same plane (Carceri), the other layer of the plane facing you (Bytopia), etc.
- Warhammer features a world with two moons, one normal looking, the other a sickly, evil green.
- The green moon is actually made entirely out of the powerful, but incredibly dangerous magical substance known as Warpstone.
- Warhammer 40,000 has this in spades - every planet has, or is implied to have, a screwed-up sky to some extent. Considering the million-something habitable worlds that make up the galaxy, that's quite a lot, and it's justified, as well. A Warp Storm over a world is liable to induce the most horrifying variety of this, too.
- This also includes Earth/Holy Terra, if you're curious. The inhabitable ecumenopolis (planet-covering city) sees a sky of smog, pollution and storms, but on a relatively clear night you can see the moon... Because it's covered with just as much infrastructure and glows brightly. If you're actually down on the surface (and not dying from millenia of refuse, toxins, radioactive waste/fallout and Warp filth) then you'll have a lovely view of the underside of the foundations of said planet-city.
- Yu-Shan, the celestial city and home of the gods, has the sky change depending on which god is currently winning the Games of Divinity.
- Also, it has Malfeas, home to The Legions of Hell, whose fake sky is lit by a green sun, which is itself an exceptionally powerful demon.
- A sun which is stated to have shared the sky with the Unconquered Sun before the Primordials were overthrown.
- You can punch it.
- Creation's physical sun and moon are gigantic artificial structures piloted across the sky, both of them entirely viable adventure settings in their own right.
- In Magic: The Gathering, Dominaria has two moons. One of them is artificial. And Mirrodin has four (and later, five) "suns."
- The Lost World of Zorandar, the setting for the Lands of Mystery supplement for the Justice, Inc. roleplaying games, has three suns.
- RuneQuest: Glorantha's Blue Moon is tiny and rarely visible save as a streak of light. Then there's the Red Moon, which is huge, half red and half black, hangs fixed in the sky over the Lunar Empire, and represents the Moon Goddess (or rather, it actually is the Moon Goddess. This is Gloranthan theology we're talking about).
- Hell in KULT has a black, dead sun. Just looking at it means it's time for a Sanity Check.
- The End in Minecraft has a dark, starless, cloudless sky that looks like TV static.
- The Nether doesn't have a sky, but the Void (normally hidden by a ceiling of bedrock) is red rather than black like outside the Overworld.
- Several Mods are examples of this as well: In The Aether it's always noon until you kill the Sun Spirit, and after that the day is still three times as long as in the Overworld, while in the Twilight Forest it's always dusk.
- Mods that let you visit the Moon (including Solar System and Galacticraft) have the Earth featured prominently in the sky.
- There are also several Texture Packs that do weird things to the sky, mostly making the sun and/or moon large and/or a weird colour, and some that have two suns.
- In Fusionfall, the show mash-up game from Cartoon Network, if you look up, you can see the evil titular planet(Planet Fusion) with half-swallowed planets from our solar system in it.
- Skies of Arcadia deserves a special mention here. Six moons (and no visible sun, despite there being a normal day/night cycle), and they're arranged in such a way that you can only see each one in a particular region of the world. Besides the Moons hanging over their country of choice, just try to fathom how that map works when you really think about it. (The two ends of Glacia should not be connected to each other if the world is round...) The game is premised on the assumption that there's no ocean and all the landmasses of the world are floating in the sky, so maybe we should just relax.
- Lunar takes place, appropriately enough, on the moon, so it has a huge floating Earth in the sky.
- The Ratchet & Clank series, taking place on multiple worlds, naturally gives a good number of odd skies to look at when you're not blowing everything to Kingdom Come.
- Tools of Destruction has a memorable part during the final battle. You teleport to another dimension, where you fight above a raging black hole against a crashing asteroid ring.
- From the same developer: Insomniac Games did the same thing with their Playstation 1 Spyro games. Enchanted Towers from Spyro 3: Year of the Dragon is one example.
- One of the many links between Tales of Symphonia and Tales of Phantasia is the names of Phantasia's two moons: Sylvarant and Tethe'alla, the names of the two worlds in Symphonia. When the original world was split in two, the residents of each world named the one moon that remained in their world after the other world, to "explain" where the missing people went. This caused some confusion when someone from the world of Tethe'alla came to Sylvarant (whose people had long forgotten about the other world). After the magical seal holding Sylvarant and Tethe'alla together -as well as a 3rd world, Derris Kharlan- gets broken, the both world's skys get all purple and cloudy.
- The world of Chrono Cross has two moons, one large and familiar-looking, the other small and red. Its predecessor Chrono Trigger, set in the same world, only had one. Turns out the second moon showed up after Dinopolis was pulled from an alternate timeline to the one the games are set in.
- Many of Psygnosis's Amiga games, usually featuring a blue-to-pink/green-to-pink gradient and an impossibly large moon.
- In FreeSpace 2 a scouting expedition is send through an ancient subspace portal. The other side of the portal lies deep inside a massive stellar nebula that limits sensor range to a few kilometers and visual range to only a few hundred meters, while usually being of a pale blue or green color. One infamous, but optional mission takes place in the center of a massive electromagnetic storm that completely shuts down sensors and missile targeting, while turning the vapors to an almost black dark red, with massive lighning discharges all around you.
- Sid Meiers Alpha Centauri is set in the Alpha Centauri star system, which consists of two mid-sized, sunlike stars (Alpha Centauri A and Alpha Centauri B) and a red dwarf (Alpha Centauri C or Proxima Centauri). The planet you colonize (officially called Chiron, usually called Planet) is the second planet of Alpha Centauri A; Alpha Centauri A and B orbit around each other in an 80-year cycle. Since the orbit is elliptical, this means Alpha Centauri B's actual distance from Planet varies noticeably, and every time Alpha Centauri B approaches perihelion (i.e., gets its closest to Alpha Centauri A) Planet gets warmer, causing the native life to pester your bases even more for a period of 20 years. However, you rarely get to see the actual sky of Planet in cutscenes.
- The manual indicates that Alpha Centauri B appears as a very bright object in Planet's night sky—brighter than the Moon is from Earth, enough to read by in the right conditions. It also indicates that the sky on Planet is yellowish.
- Chiron/Planet also has two moons, called Pholus and Nessus.
- We should pause at this point to note the connections between the names in this system to the Greek myths about the centaurs: Chiron is one of two "good" centaurs, the tutor of many minor gods, demigods, and heroes, including Asclepius, Perseus, Jason, Ajax, Achilles, and in many tellings Heracles; Pholus is the other "good" centaur, a tutor of Heracles; and Nessus is an uncharacteristically crafty centaur, responsible for killing Heracles' wife.
- The name of the trope is also used, when the opening video refers to the settlers seeking a new life "beneath an alien sky."
- After the final seal is broken, the world's sky turns from a happy blue to a blood-red. This also accompanies fireballs that rain from heaven and explode with the force of a nuclear blast, turning your recent major military victory into a devastating loss.
- In the bonus level of Drakengard, Caim and his dragon emerge in modern-day Tokyo. To emphasise that it's an alien dimension to them, everything is disturbingly in black and white.
- The first few levels of Serious Sam: The Second Encounter are supposed to take place in South or Central America, on our Earth, in the Mayan age. However, as you near the end of this set, the sky goes completely dark, and a bit later on the night-time sky is blue-purple and... is that a nebula? Cool and beautiful but quite bizarre.
- The Elder Scrolls Series features two moons in the sky: Masser and Secunda, and are the remains of a dead god. One of these moons is reddish-brown while the other is grey. Oh, and when the moons aren't full, you can see stars behind the dark parts (A Wizard Did It) The constellations and nebula shown on the night sky are also completely different, creating a beautiful spectacle. In Oblivion, the skies are even wierder, even during daytime.
- In the second game, the sky would occasionally turn green for a few hours, with no reason given. Perhaps it was a bug; perhaps it was intentional and meant to drive home the point that Nirn isn't Earth.
- Concept art and early beta footage of Elder Scrolls III: Morrowind having a daytime sky that is a pleasant shade of orange. This was scrapped in favor of a normal blue one.
- Also in Morrowind, the sun is fucking huge.
- In Oblivion, entering the eponymous Oblivion World lands you in somewhere closely resembling hell, with a red stormy sky. Going near an Oblivion Gate in Tamriel causes the same sky effect; the game can shift from a rainy, grey sky to a weather-less monstrosity that looks like it's been set completely on fire.
- Shivering Isles, Shivering Isles! It's gorgeous! Huge, multicoloured stars and nebulae streaked across a deep purple night like paint on a canvas...the first time you enter the Isles and look up, it's hypnotising. And it changes (becoming no less alien and beautiful) depending on where you are. Including a large, distorted line going the length of the sky, which follows the single prominent border in shivering isles, for its entire length.
- Skyrim continues this trope in fine fashion, not only including many of the aforementioned delights, but also with some spectacular auroras going on. Whilst they fit with the northern, snowy province, they are far more extravagant than those featured on Earth and come in some pretty otherworldly colours. One of the Dragon Shouts you can learn even clears away all the clouds, mist, and rain to show off how pretty the sky is.
- While the glorious nebulae of the previous two games are missing/heavily downplayed while on Mundus, Sovngardenote compensates. It seems that, as a general rule, Nirn's skies will look mostly ordinary (while being alien in what it actually is), while the skies of the other realms and dimensions have even more bizarre aspects visible to the naked eye. Sovngarde has some kind of giant nebula-tunnel, the Deadlands (the realm of Oblivion the gates lead to in Oblivion) and the Shivering Realms have already been mentioned, the Soul Cairn's sky has a hole in it, and Apocrypha's sky is just Hermaeus Mora himself being everywhere.
- You can also add extra alienness to Nirn's sky if you finish the Dawnguard quests as a vampire, get Auriel's Bow and Bloodcursed Arrows. You can turn the sun into a reddish-black hole thingy for a certain period of time.
- Half-Life's Xen. For all it was slated for having poor playability, arriving there and realising you're on a rock island suspended in some sort of nebula extending all the way below the horizon with no ground below you, just more startlingly alien sky... it's a pretty cool moment.
- Borderlands has planet Pandora, whose moon isn't exactly round.
- There is no sun in the sky, all sunlight is reflected off the planet's moon.
- Final Fantasy IV follows the "one normal moon like Earth's, one special plot-related moon you get to visit" pattern.
- The game confirms that the world of Final Fantasy IV is (sort of) Earth, and that the Lunarians on the second moon (which wasn't always there) came from a planet that was between Mars and Jupiter before it was destroyed, causing the Lunarians to move to a second moon orbiting Earth. The moon that the heroes don't get to visit is the one that exists in real life. The Lunarians move their moon away in the epilogue of the game.
- The world of Final Fantasy VIII has a fairly normal blue sky with one moon... except that the moon is enormous, taking up at least a quarter of the sky in most of the backdrop images. It is also, as the characters learn during the third disc, covered with monsters, and the "Lunar Cry" which carries those monsters to the planet below causes the planet-facing side of the moon to temporarily sport a huge blood-red spot with a milky white center that makes it look like a giant alien eye.
- In The Legend of Zelda: Majora's Mask, an intimidating moon growing ever-larger in the sky serves as both a timepiece and to remind players that (despite widespread recycling of character models) they're in the parallel world of Termina, not in Hyrule. Additionally, as the moon nears collision, the sky turns a sickly green during the day and reddish during the night.
- Likewise, the Sacred Realm is said to have a gold-colored sky. It is blood-red by the events of A Link to the Past.
- In Twilight Princess, the Twilight version of Hyrule has a yellowy brown sky, and there are black squares floating upwards. In the "real" Twilight Realm, the sky (such as it is) is swirling black, blue and purple.
- Grandia II has a moon similar to ours, and a smaller red one — Valmar's Moon. You get to land on it.
- Jak and Daxter: the unnamed planet has three celestial bodies: a sun, a moon, and a green, glowing planet that is out independent of day and night.
- The titular Halo of the game series has a sky that looks like a normal Earth sky....except that you can see the horizon curling up and narrowing in the distance, stretching up above you, and coming back down around to the other side.
- When you reach the Ark in Halo 3, the sky is blue but stars are visible. The Milky Way itself dominates the skyline.
- The sky of Threshold in Halo2 is angry swirling clouds.
- The sky on Reach has planets in it. However, since Reach is a human colony it is an atypically friendly alien sky.
- And on Requiem. Mostly because there's a ceiling.
- The world of Wild ARMs contains two moons. The usual boring old moon, and the new moon Malduke which is actually a huge orbiting military base built by the precursors and also serves as The Very Definitely Final Dungeon.
- The skies of Brutal Legend are a tribute to and inspired by Frank Frazetta. They shift all kinds of brilliant colors, and are never a clear blue. At night, brilliant stars and nebulae in the shape of skulls light up the night.
- Doom features several variations on a red sky for Fire and Brimstone Hell. One sky is even made out of screaming, grimacing faces.
- It gets better: One sky from an official MegaWAD is made out of what looks like twisted flesh.
- Mass Effect. One of the few things that was unique about the otherwise cookie-cutter secondary planets were the sometimes awesome exotic skies. This is particularly true with moons.
- Some explorable areas had skies that contained enormous planets and moons (which could actually get a little creepy, if only because the player would not be used to seeing things like this) ... which can make one wonder why the gravity on these planets isn't completely impossible to deal with.
- In the second game it's suggested that mass effect fields were commonly used by visitors to compensate for different gravity levels among worlds.
- One planet in the first game orbited a dying star, and was rather close. On the planet itself, this star dominated the sky. You could actually watch the surface of this alien sun boiling with its own heat. —Awesome.
- Na Pali, the planet where Unreal takes place, has two suns and two moons, which lead to some interesting landscapes and light effects. Unreal 2: The Awakening has some skies being almost completely dominated by other planets and their rings.
- Although it was never seen on screen, the manual of Tass Times in Tonetown (a game mostly set in a Totally Radical dimension) mentions a triangular moon.
- World of Warcraft has Alien Skies all over the place. Often, merely walking from one zone into the next is enough to turn the sky a completely different color (ostensibly it's always an effect of smoke or haze or the like, but it's far more dramatic than this could account for). The skies of Outland are even more exotic (and utterly gorgeous), full of an effect akin to a particularly dramatic aurora.
- The aurora-like things you see in Outland are actually parts of the Twisting Nether that is bleeding physical world after Draenor was ripped apart by opening too many portals to the Nether. The Netherstorm zone is a result of an extreme version of this process.
- Azeroth used to have two moons, but the smaller one disappeared in a patch that introduced weather effects. It's still mentioned in the background, tho.
- The entire Marathon trilogy counts, every time you get to go outside. Especially on the planet Lh'owon, where most of the second and third games take place.
- In Quake the sky was filled with ominous purple clouds; in Quake II the sky of the alien planet Stroggos was reddish-orange and sometimes had orbiting asteroids visible.
- Spore's space stage allows you "Atmospheric coloring tools", which let you dye the skies of various planets.
- In addition to planets that simply have strange skies by default. In addition to unusual colors, low-atmosphere planets have black starry skies and unusual features like binary stars, rings, or nearby gas giants can also be seen from the ground.
- Heavily utilized in the Myst/Uru series of games, to distinguish Ages located on different planets.
- In Fable I, the moon takes up a fifth of the sky, even during daytime.
- The Homeworld game has coloured space(s); in imitation of the art of Chris Foss, often seen on paperback covers of the seventies and eighties. Ship design and colours, too.
- In Team Fortress 2, the map Ctf_Doublecross originally had seven moons. Although one could write this off as a glitch or a mistake due it being nixed in a later update.
- In Deadly Premonition, the sky turns weird every time there are enemies around.
- In Metroid Prime 2: Echoes Dark Aether naturally has a purple or reddish sky, and in Light Aether, around the Temple Grounds, the sky will occasionally become unstable and shift between normal and a deep purple color.
- In Metroid Prime 3: Corruption, the planet Bryyo is tidally locked to its star, so one half of the planet is stuck in perpetual daylight, and the other is stuck in perpetual night. The area Samus explores is where the two hemispheres meet and the sky there is in a permanent state of sunset.
- In The Legend of Spyro, the world has two moons. This also plays a large role in the second game where its revealed that when they eclipse each other, it allows evil spirits to roam the world from the Well of Souls and during this time, Malefor can be set free.
- Red Faction: Guerrilla takes place on Mars, so yellow-orange sky is pretty understandable. There is also an oddly-shaped object in the sky that looks definitely out of place unless one knows that Phobos and Deimos actually have highly irregular forms.
- According to this article, both moons can be seen from the Martian surface by the naked eye (Phobos even causes partial eclipses) but Deimos is too small and faint to be identified as non-circular. Therefore, the object in question is probably Phobos.
- Quite a few galaxies from the Super Mario Galaxy games have these. Super Mario Galaxy 2 reveals that the Mushroom World has six large moons, along with the hundreds of smaller ones that serve as galaxies.
- The Sky of Lennus in Paladin's Quest is mostly normal, save for having multiple large purple moons. The flora, fauna, and overall terrain is far more alien.
- Right where you wouldn't expect it— it's possible to take screencaps in The Sims 2 showing that the Sims' world has a binary sun.
- NieR has a subtle one, and you only really notice it if you take a good look at the sky. There is constant sunlight, but you actually never see the sun itself in the sky.
- The world of Britannia in Ultima has twin moons, whose positions determine the opening and endpoint of moongates. In Ultima VIII: Pagan, you travel (or rather, are banished) to the world known as Pagan, where there's no sun in the sky - to the point one man summons a demon to ask him what the sun is.
- A rather subtle example from Kerbal Space Program: Kerbin's sun Kerbol is a red dwarf, but the sky looks pretty Earthlike until you look closely -or zoom out to map mode- and see the extra moon. Duna, meanwhile, is based heavily on the real-world planet of Mars, and has a roughly similar atmosphere. The strangest one of all, of course, is the planet Eve, which is, well, purple everywhere.
- After you arrive on Aegis 7 in Dead Space, you have a not so unusual red sky, but you also see Ishimura parked above the planet, along with an already dug-out chunk of surface. It's huge.
- The fantasy game Ravenmark takes place in the world of Eclisse. While we are never shown the sky, the manual explains that Eclisse has three moons. Additionally, a comet passes by every couple hundred years and "shines brighter than the three moons combined". There's also a strange black spot visible in the upper-right section of the sun. That last one is a little difficult to narrow down, since that would imply either that the sun rotates in the opposite direction of Eclisse's orbit and at the same rate, or that a small object is always located at the same relative spot between the sun and Eclisse. Naturally, the religions of the people of Eclisse are based on their heavens. The evil Kaysani are the worshipers of the sun god Kayes, while the Tellions revere Kayes's pet raven Corvii (the aforementioned black spot). The months on the local calendar are likewise named after the gods of the pantheon (AKA heavenly bodies). For example, the months Kayesin and Coresin are named after Kayes and Corvii, respectively.
- Super Smash Bros. Brawl:
- The Great Maze's save points take place in what appears to be another "bubble" of an area taken in by Subspace bombs, except that for some reason, the sky in the background appears to be ripping to expose the actual Subspace itself.
- Captain Falcon's final smash involves sending whoever gets caught into a track, where he soon runs them over with the Blue Falcon. It may just be an usual cloudy storm, but the sky in this setting is purple and has several "warped" shapes in it.◊
- Prevalent in No Man's Sky and unique in that you can visit those worlds and explore them, tying in with the game's emphasis on exploration and player-based discovery.
- Broken Space features Veldin, a world with an electric yellow sky, made all the more shocking for the protagonist because his home lacks a visible sky.
- Tales of the Questor has two moons in the sky, one of which is twice the apparent diameter of the other, and which have 7 and 28 day orbits (a 13 month year, with 4 weeks to a month exactly. You can tell what day of the week it is by the phases of the moons.)
- Slightly Damned has hell with a featureless sky that gets bright or dark instantly. Medius itself has a red moon and green moon.
- Pibgorn Where the ghost throws Dru.
- Smoke comics (a sub comic of WTF Comics) shows the sky as an indication smoke isn't on earth any more.
- Homestuck: Alternia has two moons (third panel on the linked page), one green, one purple which has its own little natural satellite. (The green one isn't natural) Its sun is also large, red, and invariably described as blistering.
- Then you have the various Lands inside the game's Incipispheres:
- Land of Wind and Shade: While the sky is blue and the near-omnipresent cloud cover is dark gray, said cloud cover is filled with fireflies.
- Land of Light and Rain: While the sky is blue, the clouds (and the eponymous rain) flash colourfully.
- Land of Heat and Clockwork: The sky is simply black and featureless.
- Land of Frost and Frogs: The sky seems normal... Except there are auroras everywhere! Even when the snow melts.
- Land of Quartz and Melody: The sky is purple, and there appears to be a glowing ring around the planet.
- Land of Sand and Zephyr: The sky is yellow, and yellow-tinted wind swirls constantly.
- Land of Brains and Fire: The sky is brown.
- Land of Pulse and Haze: The sky is red, the clouds are purple, and there is a constant gray mist.
- Land of Little Cubes and Tea: Both the sky and clouds are yellow.
- Land of Rays and Frogs: The sky itself is a featureless black, but the rays probably afford an amazing skyscape when viewed from the ground.
- Land of Thought and Flow: The sky and the giant neurons that populate it are all various shades of teal.
- Land of Maps and Treasure: The sky is a hodgepodge of maps, with brightly-coloured compass roses.
- Land of Caves and Silence: The sky is black and featureless.
- Land of Tents and Mirth: The sky has a glow in various shades of brown, dark yellow, and dark green.
- Land of Wrath and Angels: The sky is an all-consuming, oppressive white glow.
- Land of Dew and Glass: The sky has all this fluorescent, spiral shell stuff everywhere.
- The Alpha Kids' Lands all have featureless black skies.
- On Prospit, the sky is mostly taken up by Skaia, which looks like a giant sphere made of, ironically enough, sky. On Derse, almost all the light from Skaia is blocked by the Veil, leaving a black void.
- The Green Sun would count, but it's not actually in the sky of anywhere.
- In the Yellow Yard the "sky" is a black void lit by green, yellow and white flashes.
- On the Cherubim's planet, the sky is taken up by the sun, a red supergiant, which is later joined by a Black Hole.
- Many of the planetscape wallpapers at Digital Blasphemy qualify.
- Felarya has this trope, with a slight twist. The world is a dimensional plane which randomly connects to a sun, switching suns at, it seems, equally random intervals. Denizens wake up now and then to find a different sun in the sky - and a different night sky once the sun goes down.
- This video shows what Earth's sky would look like from various locations if a scale replica of Saturn's rings was placed in orbit around our planet.
- Here's an article from the Orion's Arm encyclopedia that makes detailed predictions of what conditions would produce what sort of Alien Sky.
- Land Games: Dark green at night, pale yellow during the day.
- The Wanderers Library has The Unwaking setting. The sun changes color with the days of the week: On Tuesday and Thursday it's red, on Monday and Wednesday it's yellow, and on Fridays and Saturdays it's blue. It used to be dark on Sunday, when Sunday was still alive. Don't ask.
- The world of The Worldbuild Project has two moons: Telusis and Quintus.
- The world of Vytal in RWBY has a moon which has been partially shattered. Monty Oum has explained that this moon is not tidally-locked, so it appears more intact at times because the unbroken side happens to be facing the planet.
- The planets Foodcourtia and Conventia in Invader Zim seem to all share a magenta-like sky. Hobo 13 has a yellow one, and others have a mostly transparent atmosphere. The stylization is truly apparent when Earth has a hideous red sky during the day, and the only time it looks normal is during a snowstorm.
- Thundarr the Barbarian actually had a plot-related reason for its Alien Sky: The moon was broken in half by a "runaway planet" passing between the Earth and the moon, plunging the world into a new dark age. This gave many tropers copious amounts of Nightmare Fuel in their youth, especially as the show indicated it would happen in the far-off year of 1994.
- The planet in Beast Wars had two moons. But one wasn't really a moon, revealed as part of the ending of season 1.
- The Futurama episode "My Three Suns" took place, appropriately, on a planet with three suns, one of which stretched from horizon to horizon. The humans and robot had no problems functioning there, though it was Death-Valley-level hot. In the Alternate Universe episode "The Farnsworth Parabox", the second universe has a psychedelic-colored sky. Amusingly, later in the Alternate Universe episode there's a shot of the (alternate) Earth from space, and it shows that the weird psychedelic sky is only a small patch over New New York. The rest of the planet looks normal, which indicates that it's probably Farnsworth's fault as all differences between the two universes were caused by coin-flips going one way instead of the other. That must have been some coin-flip...
- Most Filmation shows set in outer space have planets with green skies.
- An interesting variant in Superman: The Animated Series. It's a cloudy day, and Luminous taunts Superman, saying he can bring Superman to normal human levels. Indeed, Superman has been getting weaker and weaker. Finally Superman goes outside city limits to punch rocks and the clouds break. And that's when it hits him... the sun is RED.note
- Visionaries The alignment of Prysmos's triple suns acts as a catalyst for the Age of Magic/Science. They are often seen throughout in the background of the series.
- Ōban Star-Racers. If you're actually paying attention to the sky.
- In the Justice League multi-part episode "Hereafter", Superman is sent to a post-apocalyptic future Earth, where the sun is now red and the moon has a ring around it.
- This is later revealed to be the work of Vandal Savage, as an unfortunate side effect of his invention: a machine that controlled gravity.
- Miseryville on Jimmy Two-Shoes has three suns. "Rocket Jimmy" revealed that there are multiple moons as well.
- Xyber 9 New Dawn has Terrana, which has two moons, with both usually visible in the night sky at the same time.
- In the last few seasons of Teenage Mutant Ninja Turtles, the sky is red instead of its normal blue. This wasn't actually done by an alien but rather to convey the relatively more serious tone of those seasons.
- ThunderCats (2011) has Third Earth, which orbits a gas giant with a great spot visible on its surface. Two moons are also visible.
- Many real-life planets have skies that look very different from Earth's. Mars, for instance, normally has a tan-gray sky and two tiny moons. Weather does affect it; a violet sky has also been photographed. Venus is enveloped entirely in yellow-brown clouds, which don't change. Furthermore, there are many differently-colored stars in the universe that have planets orbiting them, meaning that those planets do indeed have differently-colored suns. That, in turn, means that not only are atmospheres different, they are differently highlighted, which widens the variety of dayglow hues.
- That without including the effects of stellar evolution (from a sun that looks not very different from ours to a huge red one when the star becomes a red giant, and finally just a very bright star when the star has become a white dwarf) or where the planet is located: just imagine, for example, the view of the Milky Way from the Magellanic Clouds or the star-studded sky of a planet in a globular star cluster.
- The Earth also has vastly different skies. The Moon has a perpetual black sky, due to lacking an atmosphere. The same effect can also be seen at high enough altitudes on Earth. Titan (the largest moon of Saturn) has a dark tan-orange sky, due to its thick atmosphere, and so lacks a view of Saturn.
- Also, Earth's moon is tidally locked, so from any one place in the near side the Earth barely moves in the sky. It just hangs there rotating on its axis and waxes and wanes depending on the time of the month i.e. the phase of the moon/earth. The sun would likewise rise every 28 days.
- Actually the color of the sky is because of the particles in the air scattering the colors in the light spectrum from the star, blue-violet is scattered and reflected back into our eyes giving the look that the sky is blue, and the sun is yellow because the other colors of light made it through the particles without completely scattering. This is because of frequencies and wavelengths, the specifics sounds utterly ridiculous so it's better if you don't know. Interesting trivia: If our sky had enough particles to scatter most of the spectrum light from the sun while letting the rays through the sky would look white and the sun an extremely deep dark shade of red.
- That does happen on occasion, when cloud conditions are right. Sometimes, people even take pictures of it.
- Occasionally one has such experiences on Earth, too. Ever wake up in a dust storm? When the millions of residents of Sydney, Australia woke up on September 23 2009 to a completely opaque red sky, there seemed to be only two things they could describe it as, neither of which any of them had experienced: The Apocalypse, or Mars.
- Big enough volcanic eruptions can change the coloration of the sky over the places where the dust travels. The Krakatoa eruption is said to have given a green hue to the sun.
- Changes in barometric pressure (such as before a tornado) turn the sky green or orange, which can look very strange, especially to people who aren't used to that sort of thing.
- A more common occurrence would be the occasional Hunter's Moon, in which the moon appears red.
- The Aurora Borealis, better known as Northern Lights (Aurora Australis if you're on the South Hemisphere) which are caused by the effect of certain solar particles on Earth's magnetic field, can look like someone was having fun finger-painting the sky.
- Excessive light pollution on Earth at night, especially on cloudy nights, can produce a yellow sky◊.
- The skies of some planets that could fall into the category of Scenery Porn. Imagine, for example, how it would be to see Saturn's rings from the planet itself, with them stretching from one side of the sky to the other like a huge rainbow (albeit with different colors). Or the skies of Jupiter, with its moons (although only Io would appear larger than ours).
- Perhaps the most spectacular view in the Solar System would be from Saturn's moon Iapetus. It's the furthest away of Saturn's large moons and orbits at an incline. Both are important; the former bit means you can see the whole ring system (except the part on the opposite side of Saturn from you, of course!), while the latter bit means you can actually see the rings in all their glory—the other moons all orbit on the same plane of the rings, so at best you'll see them as a thin line (at worst you're on Titan and can see nothing but orange haze). But on Iapetus, you see this◊. Also, Iapetus has some fantastically gorgeous mountains, plus half the moon is bright white and half is almost pitch-black; one imagines that Iapetus would be a great place for tourism.
- HD 189733b, a "hot Jupiter" exoplanet 63 light years from Earth, has a day temperature of 930 C, and 7000 km/h winds carrying molten silicate particles, which give the planet its bright blue color. In other words, it rains molten glass sideways.
