World 1 of Super Mario Galaxy 2 contains 7 Galaxies. The Boss Galaxy in this world is Bowser's Junior Gobblegut. To complete this world you will need 7 regular stars (as prankster comet stars won't be available 'till later) .
The save title for this world would be: "World 1: The Great Space Journey Begins".
(Note: this guide is only for the main course gold stars, the post game's green stars have it's own guide)
