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.
The vast hydrocarbon seas and lakes (dark shapes) near the north pole of Saturn's moon Titan sprawl out beneath the watchful eye of NASA's Cassini spacecraft. Scientists are studying images like these for clues about how Titan's hydrocarbon lakes formed.
Ultracold hydrocarbon lakes and seas (dark shapes) near the north pole of Saturn's moon Titan can be seen embedded in some kind of bright surface material in this infrared mosaic from NASA's Cassini mission.
This false-color mosaic, made from infrared data collected by NASA's Cassini spacecraft, reveals the differences in the composition of surface materials around hydrocarbon lakes at Titan, Saturn's largest moon.
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.
The shadow of Saturn cuts across the rings as seen by NASA's Cassini spacecraft. As the ring particles enter Saturn's shadow, their temperature drops to even colder temperatures, only to warm back up again when they re-emerge into the sunlight.
Saturn's A ring is decorated with several kinds of waves. NASA's Cassini spacecraft has captured a host of density waves, a bending wave, and the edge waves on the edge of the Keeler gap caused by the small moon Daphnis.
This image, taken by NASA's Cassini spacecraft, shows A beautiful 'mini-jet' appearing in the dynamic F ring of Saturn. Saturn's A ring (including the Keeler gap and just a hint of the Encke gap at the upper-right) also appears.
