Comet Observatory

The Cosmic Observatory is one of the many known areas from the upcoming Wii videogame Super Mario Galaxy. It will act as the 'hub' area, similar to Peach's Castle from Super Mario 64 and Isle Delfino from Super Mario Sunshine.

It is found in the Gateway Galaxy and is where Princess Rosalina is found. Much like the castle in Super Mario 64, certain parts of the observatory are unlocked as Mario aquires Grand Stars.
