A grayscale image of Saturn's moon Dione, captured by the Cassini spacecraft. The surface reveals bright, wispy streaks which are actually deep ice cliffs, hundreds of meters high, formed by tectonic activity. These cliffs overlay impact craters, indicating that the tectonic events are more recent. The image shows a portion of Dione's trailing hemisphere.

Close-up image of Saturn's moon Tethys, taken by the Cassini spacecraft. The surface reveals a stunning landscape of icy cliffs, craters, and unusual light-colored deposits at the crater bottoms. The image showcases the moon's unique geological features, hinting at a past liquid state and providing insights into its composition. This is one of the most detailed images ever captured of Tethys.
