Saturn's winds race furiously around the planet, blowing at high speeds which form distinct belts and zones which encircle the planet's pole, as well as its famous hexagon as seen in this image from NASA's Cassini spacecraft.
NASA's Cassini spacecraft peers down though layers of haze to glimpse the lakes of Titan's northern regions. Titan has a hydrological cycle similar to Earth's, but instead of water, Titan's lakes and seas are filled with liquid methane and ethane.
Gravity measurements by NASA's Cassini spacecraft and Deep Space Network suggest that Saturn's moon Enceladus, which has jets of water vapor and ice gushing from its south pole, also harbors a large interior ocean beneath an ice shell.
Saturn's moon Prometheus orbits near some of its handiwork in the F ring in this image from NASA's Cassini spacecraft. Prometheus and its partner Pandora gravitationally sculpt and maintain the narrow F ring.
Two pairs of moons make a rare joint appearance. The F ring's shepherd moons, Prometheus and Pandora, appear just inside and outside of the F ring (the thin faint ring furthest from Saturn) as seen by NASA's Cassini spacecraft.
Among the interplay of Saturn's shadow and rings, Mimas, which appears in the lower-right corner of the image, orbits Saturn as a set of the ever-intriguing spokes appear in the B ring (to the right of center) in this image from NASA's Cassini spacecraft.
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.
While the curtain-like auroras we see at Earth are green at bottom and red at top, NASA's Cassini spacecraft has shown us similar curtain-like auroras at Saturn that are red at bottom and purple at top. This is how the auroras would look to the human eye.
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.
