Comet Observatory

The Comet 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.

It is found in the Gateway Galaxy and is where Princess Rosetta is found. Much like Peach's Castle in Super Mario 64, or Delfino Plaza in Super Mario Sunshine, certain parts of the observatory are unlocked as Mario aquires Grand Stars.
