A Splendor Seldom Seen. NASA's Cassini spacecraft has delivered a glorious view of Saturn, taken while the spacecraft was in Saturn's shadow. The cameras were turned toward Saturn and the sun so that the planet and rings are backlit. (The sun is behind the planet, which is shielding the cameras from direct sunlight.) In addition to the visual splendor, this special, very-high-phase viewing geometry lets scientists study ring and atmosphere phenomena not easily seen at a lower phase.
Crescent Dione from Cassini, October 11, 2005 ~ Thin crescent of cratered terrain is illuminated on Saturn's fourth largest moon, Dione. As it departed its encounter with Saturn's moon Dione, Cassini sailed above an unreal landscape blasted by impacts. The rising Sun throws craters into sharp contrast and reveals steep crater walls.The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency
Callisto, Jupiter's moon-Spectacular! According to NASA, it has the darkest surface of the four Galilean moons, but is twice as bright as our moon :) It is also the most heavily cratered object in the entire solar system!
