Space Junk Galaxy

The Star Junk Galaxy is a galaxy in the upcoming game Super Mario Galaxy. This Galaxy has a futuristic/space theme. A lot of the objects are silver or blue, and there is a spaceship in it.

The Float Star is used much more than in other known galaxies. Also Toads are on a big platform covered in crystals; if Mario frees the Toads trapped in the crystals a Mushroom-shaped spaceship will appear to take Mario to the next location. There is also a wooden planet shaped like Yoshi's head.

The last unique feature of this galaxy is that it has a path that builds itself when Mario approaches it, but crumbles after he leaves.

Mario fights two bosses in this galaxy: Tarantox and Kamella.

Crystal Planet
The Crystal Planet is a planet in Super Mario Galaxy that is encountered shortly before the battle with the Colossal Scuttle Bug boss.

At first, Mario walks on top of it, which is practically a transparent crystal orb. Once he finds the passageway in, he can go under the crystal layer and explore underneath, where 1-Up Mushrooms and other treats are waiting. There are also a few Space Rabbits underneath the crystal layer, who guide Mario through to the Boost Star.

The Crystal Planet is mainly just a treat, more like a bonus planet.
