Windows to the Universe

Two views of the strange surface of Saturn's moon Iapetus. Some parts of the surface of Iapetus are bright white, while other regions are very dark. Scientist think material from another Saturnian moon, Phoebe, may be splattering onto and "staining" Iapetus. These images were captured by the Cassini spacecraft.

These are two pictures of Iapetus. Iapetus is a large moon of Saturn. The surface of Iapetus is strange. Some parts are bright white. Other areas are very dark. The Cassini spacecraft took these pictures.
