Epimetheus, seen here by NASA's Cassini spacecraft, with Saturn in the background, is lumpy and misshapen, thanks in part to its size and formation process. Bombardment over the eons has left this tiny moon's surface heavily pitted.
At first glance, Saturn's rings appear to be intersecting themselves in an impossible way. In actuality, this view from NASA's Cassini spacecraft shows the rings in front of the planet, upon which the shadow of the rings is cast.
A sinuous feature snakes northward from Enceladus' south pole like a giant tentacle in this image from NASA's Cassini spacecraft. This feature, is actually tectonic in nature, created by stresses in Enceladus' icy shell.
It's difficult to get a sense of scale when viewing Saturn's rings, but the Cassini Division (seen here between the bright B ring and dimmer A ring) is almost as wide as the planet Mercury as seen by NASA's Cassini spacecraft.
NASA's Cassini spacecraft captured this image of Saturn as it views the planet and its expansive rings from all sorts of angles. Here, a half-lit Saturn sits askew as tiny Dione looks on from lower left.
Two moons hover above the rings from this perspective, Enceladus (313 miles or 504 kilometers across), at left, and Janus (111 miles or 179 kilometers across), at right as seen by NASA's Cassini spacecraft.
Each of these two montages shows four synthetic views of Titan created using data acquired by NASA's Cassini spacecraft between 2004 and 2015. With each flyby, a brief opportunity to add small pieces to the overall mapping coverage of Titan.
The trio of ridges on Titan known as Mithrim Montes is home to the hazy Saturnian moon's tallest peak. The mountain is located midway along the lower of the three ridges shown in this radar image from NASA's Cassini spacecraft.
he view from NASA's Cassini spacecraft looks toward the anti-Saturn sides of Tethys and Rhea. North on both moons is up. Rhea and Tethys are medium-sized moons that are large enough to have pulled themselves into round shapes.
This sequence of maps shows varying surface temperatures on Saturn's moon Titan at two-year intervals, from 2004 to 2016. The measurements were made by the Composite Infrared Spectrometer (CIRS) instrument on NASA's Cassini spacecraft.
Saturn's moon Tethys appears to float between two sets of rings in this view from NASA's Cassini spacecraft, but it's just a trick of geometry. The rings, which are seen nearly edge-on, are the dark bands above Tethys.
