Saturn's outermost ring is the most active ring in the solar system. New models reveal how it came into being.
NASA's Cassini spacecraft got up close and personal with Saturn's fascinating moon Dione, revealing dramatic portraits of the icy alien satellite.
The Cassini spacecraft says its goodbyes to icy Dione in stunning style with some of the best images of the moon ever taken.
Thanks to Saturn's northern hemisphere moving into its summer -- and better lighting -- NASA's Cassini spacecraft has reported back an odd sight.
Saturn has an oddly shaped little moon that enjoys carving arcs out of one of the planet's picturesque rings. An image just released by NASA highlights that behavior.
NASA's Cassini spacecraft zooms in on the fractured surface of Dione, one of Saturn's many intriguing moons, and delivers a crater-packed close-up.
The permanent, turbulent colossal storms at Saturn's poles are a mystery -- but a new model may explain what causes them.
The Phoebe ring takes up as much space as about 7,000 Saturns, most of it pieces of dust smaller than the width of a human hair.
They're massive, violent and full of lightning, and they only arrive every 20 to 30 years. What drives Saturn's storms may be the weight of water.
Scientists think that particles found by the Cosmic Dust Analyzer on the Cassini spacecraft could hint at a watery world where life could thrive on Enceladus, one of Saturn's moons.
