Ithaca Chasma is one of the two most prominent features on Saturn's moon Tethys; the other is the gigantic crater Odysseus. Ithaca Chasma is visible near the moon's lower right limb in this image, ...
The Great Rift
A wide crater dominates the lower right of this image while part of Rhea's brightly lit, wispy terrain can still be seen near the limb of the moon. Smaller craters are overprinted upon this crater,...

A single crescent moon is a familiar sight in Earth's sky, but with Saturn's many moons, you can see three or even more.
The effects of the moon Prometheus create intricate formations in Saturn's thin F ring. The gravity of potato-shaped Prometheus (86 kilometers, or 53 miles across) periodically creates streamer-ch...
Launched on March 2, 1972, Pioneer 10 was the first spacecraft to travel through the asteroid belt, and the first spacecraft to make direct observations and obtain close-up images of Jupiter.

The shadow of Saturn's moon Dione, cast onto the planet, is elongated in dramatic fashion. The moon itself does not appear here, but the shadow can be seen south of the ringplane. This view looks ...
This bizarre scene shows the cloud-streaked limb of Saturn in front of the planet's B ring. The ring's image is warped near the limb by the diffuse gas in Saturn's upper atmosphere. For additional...
Hyperion, the eighth largest of Saturn's nearly 60 known moons, is covered in craters and landslides. Sprinkled over the icy surface is a thin layer of organic dust, which has somehow been concentr...
