Enceladus: A Tectonic Feast Credit: NASA/JPL/Space Science Institute NASA's Cassini spacecraft has been studying Saturn and its moons since it entered orbit in 2004. This image, taken on Oct. 5, 2008, is a stunning mosaic of the geologically active Enceladus after a Cassini flyby.
Saturn's Iapetus: Painted Moon- Vast sections of this strange world are dark as coal, while others are as bright as ice. The composition of the dark material is unknown, but infrared spectra indicate that it possibly contains some dark form of carbon. A leading hypothesis is that the dark material is mostly dirt leftover when relatively warm but dirty ice sublimates.
Helene Although its colors may be subtle, Saturn's moon Helene is an enigma in any light. The moon was imaged in unprecedented detail last June as the robotic Cassini spacecraft orbiting Saturn swooped to within a single Earth diameter of the diminutive moon. Although conventional craters and hills appear, the above image also shows terrain that appears unusually smooth and streaked.

Data reveal record-setting disturbances in the planet's upper atmosphere long after the visible signs of the storm abated, in addition to an indication the storm was ...
