Enceladus looks as though it is half lit by sunlight in this view from NASA's Cassini spacecraft. Images like this one are designed to capture the extended plume of icy material spraying from the moon's south polar region.
This view from NASA's Cassini spacecraft looks toward Saturn's icy moon Dione, with giant Saturn and its rings in the background, just prior to the mission's final close approach to the moon on August 17, 2015.
Some parts Dione's surface are covered by linear features, called chasmata, which provide dramatic contrast to the round impact craters that typically cover moons. This image was captured by NASA's Cassini spacecraft.
Saturn's unusual appearance in this image from NASA's Cassini spacecraft is a result of the planet being imaged via an infrared filter. Infrared images can help scientists determine the location of clouds in the planet's atmosphere.
This enhanced-color mosaic of Saturn's icy moon Tethys shows a range of features on the moon's trailing hemisphere. This image from NASA's Cassini spacecraft was constructed from 52 images from its narrow-angle camera on April 11, 2015.
As one NASA spacecraft sailed past the distant ice world of Pluto, collecting never-before-seen vistas and invaluable science data, NASA' Cassini spacecraft turned its gaze in that direction from its outpost at Saturn.
Titan may be a 'large' moon -- its name even implies it -- but it is still dwarfed by its parent planet, Saturn. As it turns out, this is perfectly normal. This image is from NASA's Cassini spacecraft.
