{{quote|Finally! [[Mario|You]] got here just in time to see the creation of my galaxy in the center of the universe! WATCH AND WEEP! From this galaxy, I'll rule a great galactic empire with [[Princess Peach|Peach]] by my side. It will last forever! I will rule every pitiful corner of the universe. So, Mario/Luigi, as you can see, I got big plans. And stomping you is at the top of my list!|Bowser|Super Mario Galaxy}}
'''Bowser's Galaxy Reactor''' is the final galaxy in ''[[Super Mario Galaxy]]''. It is located in the center of the universe and can be accessed only by talking to [[Rosalina]] on the [[Comet Observatory]]. After the player talks to her, she will transform the observatory into a comet and fly it to the center of the universe, with very minor resistance along the way. It is the only galaxy with a single star to have its own music.

This is where the final [[Grand Star]] is located, and as such features, the final battle between [[Mario]] and [[Bowser]]. During the battle, [[Bowser Jr.]] watches from the sidelines on his [[airship]] while holding [[Princess Peach]] captive. After defeating Bowser, one of the planets near his large sun implodes and turns into a supermassive [[black hole]], causing the entire galaxy to collapse in upon itself, after which it begins to suck up the entire universe, along with [[Peach's Castle]] and the Comet Observatory as well. The [[Luma]]s all throw themselves into the black hole to reverse its effects and prevent the destruction of the universe. Afterwards, the galaxy is reformed, and Mario, Peach, Bowser, and many others land safely back in the [[Mushroom Kingdom]].

==Planets/Areas==
'''NOTE''': Unless otherwise noted, all names are unofficial.
===Starting Area===
[[File:Bowser Galaxy Reactor Gravity Spotlight.png|200px|thumb|The Starting Area, the Castle Wall]]
This is the first area that [[Mario]] encounters after entering the Warp Field inside Peach's Castle. The extensive vertical walls of this strange area appear to be part of a crumbling castle. This particular section of the level contains special [[gravity spotlight]]s which allow Mario to walk directly up the vertical walls when the gravity field of the spotlights is entered. Several [[Dry Bones]] also patrol the area, and can trip Mario if he's not careful. 
{{br}}

===Lava Planet===
[[File:Bowser Galaxy Reactor Lava Planet.png|200px|thumb|left|{{conjectural|Lava Planet|planet}}]]
This planet is the first of three-element planets that are encountered one after another. The planet itself is made completely of [[lava]], though it does have multiple steel platforms rising out of the lava, along with moving sections of cooled lava which form moving pathways across the diameter of the planet. The steel platforms on the planet will begin to sink down into the lava as soon as Mario sets foot on them. The only significant obstacles that Mario will face on this planet (aside from the sinking platforms) are [[Lava Bubble]]s and [[Lava Steam]]s. A few [[coin]]s can be found on certain parts of the planet, along with a [[1-Up Mushroom]].
{{br}}

===Ice Planet===
[[File:Bowser Galaxy Reactor Ice Planet.png|200px|thumb|{{conjectural|Ice Planet|planet}}]]
This planet is similar and seemingly larger than the previous planet Mario visits, except that it is made out of ice instead of lava. It has Ice Blocks that create a path across its frozen surface. The Ice Blocks last for about six seconds before they disappear, meaning that they must be navigated quickly. The ice surface of the planet acts like lava, just like fatally cold water found in [[Snowman's Land]] of ''Super Mario 64''.
{{br}}

===Sand Planet===
[[File:Bowser Galaxy Reactor Quicksand Planet.png|200px|thumb|left|{{conjectural|Sand Planet|planet}}]]
This planet also appears to be larger than the previous planet and is the last element planet, but is made of sand. To get across this planet, Mario must follow moving stone paths to avoid [[Fire Bar]]s and quicksand that results in instant death. In this sense, it is rather similar to the Lava Planet, as both planets involve a narrow, moving pathway with a deadly substance making up the remainder of the surface and fire-based obstacles. Three [[tornado]]es can also be found here, although they are of no use to Mario, for they only lead to his [[Game Over|death]].
{{br}}

===Lava and Water Planets===
[[File:SMG BGR Lava Water Planets.png|200px|thumb|{{conjectural|Lava and Water Planets|planets}}]]
These are two unreachable planets off to the side of the element planets. One is completely made of water, and the other is made of lava.
{{br}}

===Space Junk Area===
[[File:Bowser Galaxy Reactor Space Junk Area.png|200px|thumb|left|{{conjectural|Space Junk Area|area}}]]
These are blocks that float around space, but when Mario gets close to them, the glowing blocks begin to appear beneath Mario's feet, which forms a path for him to continue. If Mario stays on the platform for too long, it will disappear. He must also deal with alterations in the gravity's direction, and time his movements to avoid Firebars.
{{br}}

===Lava Tower Planet===
[[File:Bowser Galaxy Reactor Tower Planet.png|200px|thumb|{{conjectural|Lava Tower Planet|planet}}]]
This planet is a cylinder resembling a castle tower, though the inside is walled with lava. This planet has [[Bullet Bill]]s, [[Banzai Bill]]s, and [[Thwomp]]s. Mario must travel to the end to reach the [[Launch Star]] using moving and sinking platforms while avoiding all enemies and obstacles with limited cover and a sparse supply of coins. Mario can lure Bullet Bills into [[Bowser Statue]]s for [[coin]]s there. The walls of the planet have their own gravity. There is also a hidden [[black hole]] found behind and above the planet.
{{br}}

===Stairway===
[[File:SMG Bowser Galaxy Reactor Stairway.png|200px|thumb|left|The {{conjectural|Stairway|area}}]]
This is the pathway toward the battle between Mario and Bowser. It consists of a flight of stairs. There are two side platforms that contain a [[Life Mushroom]] and a [[1-Up Mushroom]] on the left and the right of the stairs. If [[Mario]] wishes to get there, he must do it quickly or the path will crumble when [[Bowser Jr.]] shoots meteors from his airship.
{{br}}

===Bowser's Rock Planet===
[[File:SMG Bowser's Rock Planet.png|200px|thumb|{{conjectural|Bowser's Rock Planet|planet}}]]
This is the first planet is where the first stage of the final battle takes place. It has [[thorny flower|prickly plant]]s growing on the surface. Mario can have Bowser crush the plants to get Star Bits and coins.
{{br}}

===Bowser's Shell Planet===
[[File:SMG Bowser's Shell Planet.png|200px|thumb|left|{{conjectural|Bowser's Shell Planet|planet}}]]
This is the second planet where the second stage of the final battle takes place. It has [[thorny flower|prickly plant]]s and [[rubbery bulb]]s growing on the surface of it. Mario can have Bowser crush the prickly plants or spin the rubbery bulbs into the prickly plants to get Star Bits or coins.

What appears to be this planet is shown exploding in the ending cutscene of the game, expanding until it becomes a black hole.
{{br}}

===Galaxy Reactor===
[[File:Bowser Galaxy Reactor Galaxy Reactor.png|200px|thumb|{{conjectural|Galaxy Reactor|planet}}]]
This last planet is where the third and final stage of the final battle takes place. It has coin lamps and ice crystals containing coins on the surface. The reactor is surrounded by a sphere of lava that makes up the massive sun of Bowser's galaxy. The final Grand Star of the game is hidden inside the reactor. The sphere of lava, however, is not solid.

==Music==
The music that plays is an arrangement of [[Flying Mario]]'s theme and the game's main theme. It also plays in the [[Grandmaster Galaxy]] mission "[[The Perfect Run]]" from ''[[Super Mario Galaxy 2]]'', along with [[Gusty Garden Galaxy]]'s theme, [[Good Egg Galaxy]]'s theme, and the [[Comet Observatory]] theme.

==Trivia==
*On the Sand Planet, it is possible for the player to reach the [[tornado]]es by long jumping off the moving platform and Star Spinning at the ending height of Mario's long jump. The tornadoes do nothing good for the player and can occasionally launch the player into space, making Mario lose a life.
*In the ''[[Super Mario 3D All-Stars]]'' version of ''Super Mario Galaxy'', the heat-distortion effect in the lava tower only covers a small portion of the screen.
