When viewed from a distance with the sun directly behind NASA's Cassini, the larger, brighter craters really stand out on moons like Dione. Among these larger craters, some leave bright ray patterns across the moon.
Tethys, one of Saturn's larger icy moons, vaguely resembles an eyeball staring off into space in this view from NASA's Cassini spacecraft. The resemblance is due to the enormous crater, Odysseus, and its complex of central peaks.
The wavemaker moon, Daphnis, is featured in this view, taken as NASA's Cassini spacecraft made one of its ring-grazing passes over the outer edges of Saturn's rings on Jan. 16, 2017. This is the closest view of the small moon obtained yet.
It may look as though Saturn's moon Mimas is crashing through the rings in this image taken by NASA's Cassini spacecraft, but Mimas is actually 28,000 mi (45,000 km) away from the rings. There is a strong connection between the icy moon and Saturn's rings
Surface features are visible on Saturn's moon Prometheus in this view from NASA's Cassini spacecraft. Most of Cassini's images of Prometheus are too distant to resolve individual craters, making views like this a rare treat.
This view from NASA's Cassini spacecraft showcases some of the amazingly detailed structure of Saturn's rings. The image was taken in visible light with the Cassini spacecraft wide-angle camera on Sept. 24, 2016.
Two tiny moons of Saturn, almost lost amid the planet's enormous rings, are seen orbiting in this image from NASA's Cassini spacecraft. Pan, lower-right, is in the process of overtaking the slower Atlas, visible at upper-left.
Dione reveals its past via contrasts in this view from NASA's Cassini spacecraft. The features visible here are a mixture of tectonics (bright, linear features and impact cratering) the round features, which are spread across the entire surface.
Saturn's moons Tethys and Hyperion appear to be near neighbors in this view from NASA's Cassini spacecraft, even though they are actually 930,000 miles apart here. Tethys is the larger body on the left.
Rhea, like many moons in the outer solar system, appears dazzlingly bright in full sunlight. This is the signature of the water ice that forms most of the moon's surface, as seen by NASA's Cassini spacecraft.
Pan and moons like it have profound effects on Saturn's rings. The effects can range from clearing gaps, to creating new ringlets, to raising vertical waves that rise above and below the ring plane, as seen by NASA's Cassini spacecraft.
NASA's Cassini spacecraft spies a bright disruption (features known as 'jets') in Saturn's narrow F ring suggesting it may have been disturbed recently, though not by Pandora which lurks nearby at lower right.
