Dione and Saturn

Cassini recently flew by the Saturnian moons Titan and Dione and sent back some beautiful images. In the background image Dione is seen against the background of Saturn. What a remarkable vista if one could stand on the tiny moon and see Saturn filling up the entire sky.

White streaks across the surface of Dione seen in images from past space probes were thought to be ice deposits. The latest images surprised scientists by revealing that the streaks are actually tall cliffs and fracturing caused by tectonic activity.
