Gateway Galaxy

The Comet Observatory in the Gateway Galaxy.

The Gateway Galaxy is one of the many galaxies from the Wii videogame Super Mario Galaxy. 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 (Grand Star Rescue), Mario won't be able to return to this Galaxy until he unlocks the "Garden", later on in the game.
