Gateway Galaxy is the first galaxy that Mario goes in Super Mario Galaxy. It is the first place Star Bunnies and Rosalina are introduced. Lumas are also properly introduced here. After completing this galaxy, you will be transported to the Comet Observatory. The Gateway Galaxy can not be accessed again until power is brought to the Garden. However, only the starting planet can be accessed.
