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.
This image shows a region in Saturn's outer B ring. NASA's Cassini spacecraft viewed this area at a level of detail twice as high as it had ever been observed before. And from this view, it is clear that there are still finer details to uncover.
This image from NASA's Cassini spacecraft shows a region in Saturn's outer B ring. The view here is of the outer edge of the B ring, at left, which is perturbed by the most powerful gravitational resonance in the rings.
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.
This view, seen by NASA's Cassini spacecraft, shows Saturn's daylit side, which no Earth-based telescope could capture. A spacecraft in orbit, like Cassini, can capture stunning scenes that would be impossible from our home planet.
Sunlight truly has come to Saturn's north pole. The whole northern region is bathed in sunlight in this view from NASA's Cassini spacecraft, late 2016, feeble though the light may be at Saturn's distant domain in the solar system.
This comparison of two views from NASA's Cassini spacecraft, taken fairly close together in time, illustrates a peculiar mystery: Why would clouds on Saturn's moon Titan be visible in some images, but not in others?
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
This collage of images from NASA's Cassini spacecraft shows Saturn's northern hemisphere and rings as viewed with four different spectral filters; each is sensitive to different wavelengths of light and reveals clouds and hazes at different altitudes.
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.
NASA's Cassini spacecraft captured Saturn's north polar region displaying its beautiful bands and swirls. Where they meet and flow past each other, the bands' interactions produce many eddies and swirls.
