16	A subtrope of ArtisticLicenseSpace.
17
18	Hollywood is not interested in teaching or even researching physics, and generally doesn't even depict normal explosions on Earth accurately, so it's no surprise that explosions in space rely on RuleOfCool rather than science. In the movies, explosions in space work pretty much the same way explosions on Earth would (or rather the way film-makers ''imagine'' they would, with lots of red flames and smoke).
19
20	In reality, space has no air to transfer the explosive energy to. Thus, explosions would have an initial brilliant flash, and the resulting ''[[https://www.youtube.com/watch?v=8IJ74IvpBlU spherical]]'' fireball and debris would travel away from the point of explosion far too fast for the eye to see. Do note that without any atmosphere or gravity to act on the debris, it will continue on at full speed until it hits something, meaning such an explosion could actually be ''more'' dangerous than it would have been in an atmosphere.
21
22	Nuclear explosions would be similar, but with a much brighter flash, and little or no visible debris since it would be vaporized.
23
24	Explosions in vacuum on the surface of a planet, moon, asteroid etc. will look similar to those in zero-g, but any debris that does not achieve escape velocity in the local gravity field will arc back down and rain to the surface. In low gravity, this could take minutes or even hours.
25
26	Further, if a spacecraft blows up, the explosion should have the same velocity as the craft did (possibly altered by the velocity of whatever hit it). I.e., the boom should keep moving. Many movies and shows have a fast-moving craft turn into a ''stationary'' explosion (relative to the camera).
27
28	Above all, explosions in vacuum would be [[SpaceIsNoisy silent]].
29
30	In many cases, this is caused by the method of special effects: actual pyrotechnics in an atmosphere. It should be noted that this is generally considered an [[AcceptableBreaksFromReality Acceptable Break From Reality]] by the majority of the audience. Some works even try to find ways to work around it. One way is fictional elements used as fuel for ships, which are very flammable.
31
32	Many Hollywood Explosions In Space will also include a PlanarShockwave.
33
34	This is such an ubiquitous trope that only aversions and subversions should be listed.

40	[[folder:Anime & Manga]]
41	* Most explosions in space combat scenes in most ''Franchise/{{Gundam}}'' series' follow the more realistic quickly-fading spherical explosion pattern. There usually doesn't seem to be much debris, though, but it may just be vaporized by the Mobile Suit's compact reactors failing catastrophically.
42	* ''Anime/{{Macross}}'' is also another big user of the spherical explosions, in or out of space.
43	* ''Manga/{{Planetes}}'', being a hard science fiction, averts this. When [[spoiler:a space center on the Moon where a giant spacecraft engine is constructed]] blows up, an immense cone of ejected matter is shown, in a realistic and [[OhCrap terrifying]] way.
44	[[/folder]]
45
46	[[folder:Comic Books]]
47	* In the DCAU tie-in ''WesternAnimation/JusticeLeague'' comic story "[[PunnyName Disarmed]]", Green Lantern evicts an alien bomb off of Earth, making a comment that he never gets used to how quiet explosions are in space. The explosion is represented primarily as a sphere of light (with pointy bits on the compass points).
48	[[/folder]]
49
50	[[folder:Fan Works]]
51	* Mostly averted in ''Fanfic/{{Bait and Switch\|STO}}'' and ''Fanfic/RedFireRedPlanet'', a pair of ''VideoGame/StarTrekOnline'' fics with CharacterOverlap. Ships that suffer a warp core or fusion bottle breach tend to be described as going up in a "retina-searing white flash" or something similar. Other destroyed vessels tend to leave large chunks of themselves behind, such as a Jem'Hadar attack ship that had its front half blown away by a shot to the torpedo magazine.
52	* ''Fanfic/RocketshipVoyager''. During the climatic battle against the Psiborg Collective inside a decompressed docking bay, one of the SpaceMarines is eager to NukeEm, but it's pointed out that a) the lack of air reduces the effectiveness of nukes with no blast wave, and b) Voyager is surrounded by an electromagnetic field to keep out cosmic radiation, so if you set off a nuke ''inside'' that field it concentrates the radiation there like the Van Allen belt.
53	[[/folder]]
54
55	[[folder:Films -- Live-Action]]
56	* In ''Film/TwoThousandOneASpaceOdyssey'' when Bowman blows the explosive bolt hatch, the sound of the explosion is cut short by the decompression.
57	* In ''Film/SilentRunning'', nuclear explosions in space are just circular flashes that fade away.
58	* Shown accurately once ([[SpaceIsNoisy except for the sound]]) in ''Film/TheFifthElement'' [[spoiler:when Korben blows off the docking bay doors to escape the hotel]], otherwise, used in every other explosion in the movie.
59	* In ''Film/{{Apollo 13}}'', the explosion accurately depicted the real life event, except for the spacecraft careening about from said explosion. The venting of a leaking oxygen tank kept pushing them about for a time.
60	* Done mostly correctly at the tail end of ''Film/TheAvengers2012''. The nuke that [[spoiler:Iron Man steers into the enemy mothership]] detonates as an expanding sphere, with no PlanarShockwave or other Hollywood contrivance. Not quite right, but closer than Hollywood usually gets.
61	* Most of ''Franchise/StarWars'' plays this trope quite straight, but in the climactic assault on the first Death Star, one unfortunate Y-Wing is shown continuing to move as it is destroyed.
62	* Also done correctly with the orbital cascade effect in ''Film/{{Gravity}}''.
63	* Justified in the explosion in ''Film/{{Interstellar}}'' as it is fueled by oxygen form inside the spacecraft and is [[SpaceIsNoisy realistically soundless]] when observed from another spacecraft.
64	* Realistically depicted in the climax of ''Film/RobotJox'', as the explosions during the final fight between Achilles and Alexander, which goes to the heights of space, have no sound when seen from outside.
65	* ''Franchise/StarTrek'' movies repeatedly have played this trope very straight.
66	** In ''Film/StarTrekIITheWrathOfKhan'', it's revealed early on that the sixth planet in a star system exploded, causing a shockwave that knocked the fifth planet off its orbit, turning it into a desolate wasteland. Mike Okuda points out in the commentary that shockwaves do not propagate through the vacuum of space.
67	** In ''Film/StarTrekVITheUndiscoveredCountry'', Praxis' explosion produces a planar shockwave that knocks everyone on the bridge of the Excelsior out of their chairs, those sleeping out of their beds, etc. As with the above example, shockwaves do not propagate through the vacuum of space. This is [[HandWave handwaved]] by Commander Valtaine referring to it as a "sub-space shockwave," though it isn't made entirely clear.
68	** In ''Film/StarTrekGenerations'', the plot revolves around a missile of sorts that can stop all nuclear fusion within a star. The idea is that without the star's gravity to change its course, the energy ribbon would be redirected to the surface of the planet the villain is on. This, of course, would not produce a shockwave (since, at the risk of being repetitive, shockwaves don't propagate through the vacuum of space), and hence not destroy any of the planets immediately, though the people living in the Veridian system would presumably freeze to death without the heat of their sun, eventually. But because [[RuleOfDrama dramatic tension must be maintainted]], a shockwave is seen destroying Veridian III.
69	* There are a few times in ''Film/OurFriendPower5'' when giant, fiery explosions happen in the middle of space, due to the characters being aliens engaged in combat.
70	[[/folder]]
71
72	[[folder:Literature]]
73	* In the ''Literature/HonorHarrington'' series, ships that have their fusion bottle fail just have a "single, eye-searing flash," and then are gone. It's also mentioned that nuclear warheads are only useful as weapons in space if they get a direct hit (which is highly unlikely, though it does happen on occasion), which is why missile weapons had moved on to using bomb-pumped lasers by the start of the series.
74	* In Creator/MatthewReilly's ''Area 7'', when a space shuttle gets hit by a missile, it simply cracks.
75	* In the American ''Robotech'' novels, explosions in space are ''always'' spherical.
76	* In ''[[Literature/TheShipWho The City Who Fought]]'', a starship whose drive systems are going critical explodes near the protagonists' space station, and the resulting debris field makes venturing outside extremely hazardous for quite a while.
77	* ''Literature/TheHistoryOfTheGalaxy'' series generally tends to describe explosions in space correctly. Usually, the danger is not the explosion itself, but the debris flying from the exploding ship or station in every direction at high speeds.
78	* In another novel, a hyper-advanced ship (officially classified as a [[StandardSciFiFleet light cruiser]] but with enough firepower to take out a conventional fleet) is mentioned to be armed to the teeth with nuclear missiles. The author then proceeds to explain that, in space, this really isn't as dangerous as it sounds. With advanced [[PointDefenseless point-defense]] systems and EM shielding (protecting from nuclear radiation and EMP), a ship can be effectively immune to a nuclear barrage, as nuclear explosions (without any matter to "feed" on or air to move) only have an effective range of a few miles.
79	* In ''Literature/TheLostFleet'', ships explode in a brief bright flash only in two cases: reactor containment fails, or two ships collide at an appreciable fraction of the speed of light (ships normally maneuver at 10% of c). In both cases, little is left of the ship after the flash. Most ships that are destroyed in battle simply break apart and continue on their original trajectory, as pieces start to move apart.
80	* In Creator/RobertAHeinlein's ''Literature/BetweenPlanets'' it is done correctly when Circum-Terra Station was destroyed by a nuclear weapon. The blast was described as a second sun, blazing white, and as an expanding, perfectly geometrical sphere. The story also explicitly states that there would not be a mushroom cloud in the vacuum of space.
81	* ''Track'' (a 1980's action-adventure series by Jerry Ahern). In "Revenge of the Master" a neo-Nazi bomb maker plans to explode a bomb on board the Space Shuttle, and gives some thought to how the vacuum will affect the explosion.
82	* In the 1940's ''Venus Equilateral'' tales by George O. Smith, the eponymous SpaceStation is being threatened by a SpacePirate. Various means of defense are considered including guided [[SpaceIsAnOcean torpedoes]]. However it's pointed out that explosives have little effect in a vacuum as there is no atmosphere to create a pressure wave, shrapnel might not penetrate the hull and even an armor piercing warhead has to hit the fast-moving spaceship in the first place.
83	* When [[UsefulNotes/MarieCurie Curie's]] irradiated brain goes critical in ''Literature/EmperorMolluskVersusTheSinisterBrain'', Mollusk has it thrown into space before it could detonate.
84	[[/folder]]
85
86	[[folder:Live-Action TV]]
87	* Like every SciFi show, ''Series/StargateSG1'' and ''Series/StargateAtlantis'' have this. However, when they use nukes, the explosions are at least spherical and without a mushroom cloud.
88	* In ''Series/{{Firefly}}'', damaged ships (such as a derelict freighter blown up by an Alliance cruiser in "Bushwhacked") simply break up, with the broken parts drifting in the trajectory of the ship. There was also no sound of the explosion of break up (which was true for most space shots in Firefly)
89	* There are lots of these in ''Franchise/StarTrek'' after a StandardStarshipScuffle with an enemy vessel. Averted in ''Series/StarTrekTheOriginalSeries'', where starships that are damaged enough will have their life support systems fail, [[SurprisinglyRealisticOutcome leading to the deaths of the crew]], and the ship becoming a drifting wreck.
90	* In ''Series/{{Battlestar Galactica\|2003}}'', explosions usually die out quickly and fiery explosions (which are caused by oxygen in the ships that blow up themselves -- the reason why Cylon raiders hardly ever blow up but just disintegrate mostly) appear 'smeared' by velocity. Also, nuclear explosions do appear mostly as 'just flashes' as described above, without the trope-ish fireball and/or mushroom clouds. While capital-ship shots were generally silent, smaller fighter craft generally had full sound in space. The creators fully intended for all space battles to be silent, but upon viewing the results, decided it was too unnatural and inserted sound effects. In a nod to original intent, all sound effects in space are still noticeably subdued.
91	* Averted in ''Series/TheExpanse''. When a ship is nuked, it breaks apart and vanishes in a bright flash and spherical blue explosion. Another nice touch is that ships don't actually explode without the application of explosives, as seen in "Doors and Corners," when ''Rocinante'' wins a space battle by Swiss-cheesing their opponent with PDC[[note]] Point-Defense Cannons, large-caliber [[GatlingGood rotary-barrel machine guns]] similar in form and function to the Phalanx CIWS guns on real-life warships[[/note]] rounds, killing the crew without actually blowing up the ship.
92	[[/folder]]
93
94	[[folder:Newspaper Comics]]
95	* A ''ComicStrip/TheFarSide'' strip [[ConversationalTroping mocked]] this trope (and SpaceIsNoisy). A scientist jumps up in a crowded theater, yelling "Stop the movie! Stop the movie! Explosions don't go 'boom' in a vacuum!"
96	[[/folder]]
97
98	[[folder:Tabletop Games]]
99	* ''TabletopGame/BattleTech'': This trope is averted as the rules and descriptions. In numerous places it's pointed out that nuclear weapons, for example, are significantly less powerful in space because there's no atmosphere for shockwaves to spread through while characters who are used to fighting on the ground will often make note of how different explosions look in space.
100	* Though the visual isn't discussed, explosions in ''TabletopGame/{{GURPS}}'' lose about half of their power when in space due to lack of atmosphere.
101	[[/folder]]
102
103	[[folder:Video Games]]
104	* In ''VideoGame/EveOnline'', the explosion effects look pretty much correct according to what is described above. They are slowed down, however, so that the players can savor in the shiny afterglow of the ship they just helped blow up. They do get the "Explosion moves on original trajectory at original velocity" bit, at least. Sadly, the same can't be said for the wreck that's left behind, though that's so you don't have to go chasing it down when you want to loot it. The Sound Effects are justified in game by the simple fact that everything you see as a pod pilot is a VR simulation of actual events, piped directly into your head while you are safely curled up inside your pod full of goo. Apparently early versions of the Pod tech didn't bother with Sound but the lack of it tended to send the (already mentally unbalanced) capsuleers completely insane.
105	* ''Franchise/StarFox'' games do this as well, with ships mostly breaking apart after being hit or the classic "BOMB" item going in a perfect sphere.
106	* Slyly justified in the early PC game ''VideoGame/{{Elite}}''. The manual explained that when a ship or similar explodes in space, as well as the flash it produces a burst of radio waves which, hitting your communicator, make a sound ''just like'' an explosion.
107	* While ''Franchise/DeadSpace'' games gets the workings of gravity and vacuum right most of the time, in [[VideoGame/DeadSpace2 the second game]] there is a curious exception. In a zero-gravity area (with oxygen) there is a large, roaring fire. Despite the lack of gravity, the flames are reaching "upwards", instead of expanding in all directions.
108	* In ''VideoGame/SwordOfTheStars'' nukes produce a small spherical blast in space, and the only other explosives are acid and nanite bombs that leave a sphere-shaped corrosive cloud. And when used in OrbitalBombardment nukes produce a sphere again but substantially bigger. When ships are destroyed, their parts continue to travel in the same direction for a few seconds before they blow up. This is even true of [[DolphinsDolphinsEverywhere Liir]] ships which, technically, don't move in the Newtonian sense but teleport millions of times per second. Thus, when Liir ships are destroyed, their wrecks should stay relatively at rest.
109	* The enemy ships in ''VideoGame/{{Rodina}}'' will turn into a fiery wreck if you shoot them enough. Your ship will also do that if it loses all of its health, or if it catches on fire.
110	[[/folder]]
111
112	[[folder:Webcomics]]
113	* ''WebComic/AMiracleOfScience'' is careful to make sure to accurately portray the behaviour of explosions in space ''and'' waste gases from factory smokestacks on the Moon (ItMakesSenseInContext, amazingly) that can be seen in the background of one page. The comic's creators ''really'' have ShownTheirWork.
114	* ''WebComic/{{Starslip}}'' [[http://starslip.com/2010/02/18/onomatopyewpyew lampshades this trope]] in a storyline about the [[SpaceNavy Astry's]] combat exercises. One of [[TheCaptain the captains]] complains that the battle doesn't feel like the real thing -- because the damage is all simulated, and [[RealityIsUnrealistic there are no explosions in space]] when a ship is hit.
115	-->'''Capt. Zarde:''' ''[[SayingSoundEffectsOutLoud Pyew! Pyow Bwommmkssrrch!]] Augh! This sucks!''
116	* ''WebComic/TheInexplicableAdventuresOfBob'' has shown space explosions twice so far. The first one was accompanied by the UnSoundEffect [[https://bobadventures.thecomicseries.com/comics/44 "SILENT KABOOM!"]] The second one quickly morphed into a [[https://bobadventures.thecomicseries.com/comics/514 fireworks display,]] with the onlookers' screams changing to "Oooh! Ahhh!"
117	* Averted in ''Webcomic/TheAdventuresOfDrMcNinja'' when [[spoiler:King Radical becomes President and has his vice president [[TheDragon Ron Wizard]] [[http://drmcninja.com/archives/comic/31p06/ detonate all of Russia's nukes in space]] to simultaneously present himself as an unassailable world power and [[VillainWithGoodPublicity a hero for peace]].]] The explosions are drawn realistically with the AltText thanking the Kennedy administration for providing reference photos.
118	[[/folder]]
119
120	[[folder:Web Original]]
121	* In ''WebVideo/SuperMarioLogan'''s "Bowser Junior Goes To The Sun!", Junior's Space Shuttle (named Octopus) explodes when it gets too close to the Sun.
122	[[/folder]]
123
124	[[folder:Western Animation]]
125	* In ''WesternAnimation/IlEtaitUneFois''''... Space'', ships in space usually blow up in spherical explosions [[spoiler:especially when the Cassiopeian fleet, and especially their Nautilus-class warships, is being obliterated in mass by the Humanoids]], that often do not even expand. They ''always'' come with sound, however, and in one episode a warship from the Omega Confederation after being hit explodes producing a planar shockwave.
126	[[/folder]]
127
128	[[folder:Real Life]]
129	* Back in the day the two Superpowers conducted several series of [[http://en.wikipedia.org/wiki/High_altitude_nuclear_explosion high altitude nuclear explosions]] that resulted in fireballs being as cool if not cooler than anything Hollywood could produce well into the age of CGI. Just another example of something that's just as easy to get wrong as right. It should be noted that these explosions were still in the atmosphere, just very high up.
130	** [[https://en.wikipedia.org/wiki/Starfish_Prime Starfish Prime]] was a 1962 high-altitude nuclear detonation that was very definitely - ''legally'', at least - in outer space (at 250 miles / 400 km up, 300 km above the Kármán line[[note]]which distinguishes between atmosphere and space for purposes of regulating craft - spacecraft and aircraft fall under different regulations[[/note]] and not far below the present-day altitude of the ISS). It also contributed to the early demise of a number of satellites, including the first commercial communications satellite, Telstar-1, and affected the UK's first satellite, Ariel-1. Although in that case, by a remarkable coincidence, one of the things that was damaged was the timer that was supposed to end the satellite's operations after a year - as a result, Ariel-1 continued to operate for far longer than expected, albeit with sub-optimal solar panels (thanks again to radiation from Starfish Prime and other high-altitude tests). The satellite damage from Starfish Prime was one reason for the treaty banning nuclear tests in space that is mentioned below.
131	* Nuclear explosions in space would cause damage in a very different way than nuclear explosions in an atmosphere. A nuclear explosion in a vacuum produces a bright flash, a burst of neutrons, and a burst of intense radiation that rapidly declines in effect due to the Inverse Square Law. The actual damage to a target would come from the radiation and neutrons, which would fry the crew plus any electronics, and leave the target highly radioactive.
132	** The Casaba-Howitzer experiments were attempts to make spaceborne nukes viable, developed to meet the OrionDrive prerequisite of a "shaped nuclear charge". By attaching a thin tungsten plate to a warhead, one gets [[WaveMotionGun a beam of atomic fire]]; by attaching a thick styrofoam pillar to it instead gets [[ShortRangeShotgun a wide "pancake" of nuclear debris.]] Or so it was thought because the experiments were canned after a treaty barring atomic weapons in space was ratified.
133	* A faulty spy satellite is said to [[https://www.youtube.com/watch?v=OhdHkoal31o&feature=related have been shot down with a missile]] by the US Navy, to prevent it from becoming a hazard. Note that most satellites are actually still within the atmosphere. (GPS satellites and the geosynchronous communication satellites used by everyday fixed dish antennas are two notable exceptions.)
