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.
Since images like this can only be taken while the sun is behind the planet, this beautiful view is all the more precious for its rarity. Earth does not appear in this mosaic as it is hidden behind the planet.
