Saturn's D ring is easy to overlook since it's trapped between the brighter C ring and the planet itself. In this view from NASA's Cassini spacecraft, all that can be seen of the D ring is the faint and narrow arc as it stretches from top right of the ima
Although the crack-like features seen here on Dione's surface appear wispy and faded, they are in reality a series of geologically fresh fractures as seen in this images captured by NASA's Cassini spacecraft.
Saturn's F ring often appears to do things other rings don't. In this image from NASA's Cassini spacecraft, a strand of ring appears to separate from the core of the ring as if pulled apart by mysterious forces.
NASA's Cassini spacecraft captures a still and partially sunlit Enceladus. The Saturnian moon is covered in ice that reflects sunlight similar to freshly fallen snow, making Enceladus one of the most reflective objects in the solar system.
Using a special spectral filter, NASA's Cassini spacecraft was able to peer through the hazy atmosphere of Saturn's moon Titan. This image features the largest seas and some of the many hydrocarbon lakes that are present on Titan's surface.
Slipping into shadow, the south polar vortex at Saturn's moon Titan still stands out against the orange and blue haze layers that are characteristic of Titan's atmosphere. Images like this, from NASA's Cassini spacecraft.
While the moon Epimetheus passes by, beyond the edge of Saturn's main rings, the tiny moon Daphnis carries on its orbit within the Keeler gap of the A ring in this image from NASA's Cassini spacecraft.
On July 19, 2013, in an event celebrated the world over, NASA's Cassini spacecraft slipped into Saturn's shadow and turned to image the planet, seven of its moons, its inner rings, and, in the background, our home planet, Earth.
A single jet feature appears to leap from the F ring of Saturn in this image from NASA's Cassini spacecraft. A closer inspection suggests that in reality there are a few smaller jets that make up this feature.
NASA's Cassini spacecraft captured this image of Tethys, telling the story of a violent history marked by impacts. Seen here are the craters Melanthius (near the center), Dolius (above Melanthius), and Penelope (upper left almost over the limb).
NASA's Cassini spacecraft uses special infrared glasses to peer through Titan's haze and monitor its surface inequatorial region dubbed 'Senkyo.' The dark features are believed to be vast dunes of hydrocarbon particles.
Although their gravitational effects on nearby ring material look quite different, Prometheus and Pan are both shepherd moons, holding back nearby ring edges in this image captured by NASA's Cassini spacecraft.
