{{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]].
==Layout==
===Starting area===
[[File:Bowsers Galaxy Reactor.png|200px|thumb|The starting area.]]
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 is not careful. 
===Elemental planets===
[[File:Bowser Galaxy Reactor Lava Planet.png|200px|thumb|left|The lava-covered planet.]]
The first planet Mario is brought to is the first of three planets that are based on different environmental hazards. This one is completely covered [[lava]], with only some steel platforms and moving rocky terrain being the only nondamaging footing. The steel platforms sink down into the lava as soon as Mario sets foot on them. The only significant obstacles that Mario will face on this planet are [[lava burst]]s and [[fire geyser]]s. A few [[coin]]s can be found on certain parts of the planet, along with a [[1-Up Mushroom]].

[[File:Bowser Galaxy Reactor Ice Planet.png|200px|thumb|The ice sphere.]]
The '''ice sphere'''<ref>{{cite|author=Black, Fletcher|title=''Super Mario Galaxy'' PRIMA Official Game Guide|page=299|date=November 9, 2007|publisher=[[Prima Games]]|language=en-us|isbn=978-0-7615-5643-5}}</ref> is the second elemental planet in the galaxy. It is slightly larger than the previous planet and is covered in ice so cold that it damages Mario like lava would, similar to the [[freezing water]] from [[Snowman's Land]] in ''[[Super Mario 64]]''. The ice sphere is the only place this type of ice occurs in the entire game. Normal [[ice]] platforms come together to form a path above the planet's surface that Mario can [[skate]] across. They last for about six seconds before disappearing, meaning that they must be navigated quickly.

[[File:Bowser Galaxy Reactor Quicksand Planet.png|200px|thumb|left|The sand-covered planet.]]
The final planet in this series that is accessible to Mario is the largest of three and is covered in [[quicksand]]. To get across this planet, Mario must follow moving stone paths to avoid [[Fire Bar]]s. Three [[tornado]]es occur on the surface, although they are of no use to Mario. It is possible for the player to reach the tornadoes 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 addition to the three described planets, there are two similar ones inaccessible in the galaxy. One is covered in [[water]], while the other resembles a sun, which is where Bowser ends up after his defeat, and a black hole forms by its explosion.

===Final areas===
Following the quicksand-covered planet is a two-dimensional area that must be navigated using [[cosmic block]]s. Unlike the other cosmic blocks found in previous galaxies, these ones begin to vanish after moving into place. The pull of gravity in this area also shifts, necessitating he a good pace without being hit by spinning Fire Bars.

[[File:Bowser Galaxy Reactor Tower Planet.png|200px|thumb|The cylindrical planet.]]
The next planet is a cylinder resembling a castle turret. The inner walls are covered in lava. This planet has [[Bullet Bill]]s, [[Bomber Bill|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.

[[File:SMG Bowser Galaxy Reactor Stairway.png|200px|thumb|left|The stairway to Bowser.]]
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 respectively. If Mario wishes to get there, he must do it quickly or the path will crumble when [[Bowser Jr.]] shoots meteors from his airship.

===Battle planets===
[[File:Bowser Galaxy Reactor Galaxy Reactor.png|200px|thumb|The final planet from the battle with Bowser.]]
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.

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.

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.
