In this unusual photo, Enceladus is lit by the Sun as a very thin crescent. Saturnshine illuminates part of its nightside. Light scattered by the icy particles of the E ring brightens the background. The south polar plumes scatter sunshine as well, making a fuzz at the bottom of the crescent. In the background, a few stars make streaks in this long-exposure Cassini image, which was taken on February 18, 2005.
