Spiderweb-like Fractures in Occator Crater
The Cassini spacecraft looks toward the sunlit face of Saturn's rings, whose shadows continue to slide southward on the planet toward their temporary disappearance during equinox in August 2009. T...
Eyes on the Rings
The Cassini spacecraft captures Saturn's ever-changing F ring, showing its bright core, another strand of ring material, and a breakaway clump of material close to the core. The F ring core is the...
Until recently, Saturn's tiny moon Enceladus was thought to be cold and dead. But close observations by the Cassini spacecraft have revealed dramatic features and made this frozen world a new targe...
Saturn Moons Explorer -- Enceladus
Cassini radar sees sand dunes on Saturn's giant moon Titan (upper photo) that are sculpted like Namibian sand dunes on Earth (lower photo). The bright features in the upper radar photo are not clou...
Titan's Sand Dunes
Two large craters lie along the boundary between day and night on Saturn's moon Rhea. The bright spots in the middle of each crater may be prominent central peaks. Rhea is 1,528 kilometers (949 mi...
Images taken of Saturn's rings by Cassini immediately after it entered orbit around Saturn have turned up circumstantial evidence that an unseen moon may be orbiting dead center in the narrow Keele...
Fingerprints of an Unseen Moon?
This image of Ceres, taken by NASA's Dawn spacecraft, shows terrain in the southern hemisphere within the large crater called Yalode. The prominent crater at top-right is called Lono. The crater di...
