Although Dione (near) and Enceladus (far) are composed of nearly the same materials, Enceladus has a considerably higher reflectivity than Dione. As a result, it appears brighter against the dark night sky as seen by NASA's Cassini spacecraft.
Although Epimetheus appears to be lurking above the rings here, it's actually just an illusion resulting from the viewing angle of NASA's Cassini spacecraft. In reality, Epimetheus and the rings both orbit in Saturn's equatorial plane.
During its closest ever dive past the active south polar region of Saturn's moon Enceladus, NASA's Cassini spacecraft quickly shuttered its imaging cameras to capture glimpses of the fast moving terrain below.
The south polar region of Saturn's active, icy moon Enceladus awaits NASA's Cassini spacecraft in this view, acquired on approach to the mission's deepest-ever dive through the moon's plume of icy spray.
NASA's Cassini spacecraft captured this view as it neared icy Enceladus for its closest-ever dive past the moon's active south polar region. The view shows heavily cratered northern latitudes at top, transitioning to fractured, wrinkled terrain.
NASA's Cassini spacecraft spied this tight trio of craters as it approached Saturn's icy moon Enceladus for a close flyby on Oct. 14, 2015. The craters, located at high northern latitudes, are sliced through by thin fractures.
This view from NASA's Cassini spacecraft shows battered terrain around the north pole of Saturn's icy moon Enceladus. Craters crowd and overlap each other, each one recording an impact in the moon's distant past.
This global digital map of Saturn's moon Titan was created using images taken by NASA's Cassini spacecraft's. The map was produced in June 2015 using data collected through Cassini's flyby, known as 'T100,' on April 7, 2014.
Titan and Saturn share a hazy appearance in this image from NASA's Cassini spacecraft, though Saturn is a gas giant with no solid surface to speak of, and Titan's atmosphere is a blanket surrounding an icy, solid body.
Prometheus and Pandora are almost hidden in Saturn's rings in this image captured by NASA' Cassini spacecraft. Prometheus is the left most moon in the ring plane, roughly in the center of the image. Pandora is towards the right.
Why does Saturn look like it's been painted with a dark brush in this infrared image, but Dione looks untouched? NASA's Cassini spacecraft took this image in a wavelength that is absorbed by -- methane.
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.
