Saturn's Iapetus: Painted Moon in 3D
Saturn's moon Iapetus has a dark side and a bright side, almost like it was painted. The Cassini spacecraft flew by it in 2004, taking pictures that show this strange moon in detail. We still don't know what makes the dark material so black. Iapetus also has a ridge around its equator, making it look a bit like a walnut.
