Gateway Galaxy

The Gateway Galaxy is one of the many Galaxies from Super Mario Galaxy for the Wii. Princess Rosalina calls this galaxy the "Gateway to the Starry Sky". It serves as the opening level for the game and is the location of the Cosmic Observatory. This is the first Galaxy in the game, and after Mario clears the first level in the Galaxy, he won't be able to return until he unlocks the Garden, later on in the game.
