Light and shadow
Capturing the interplay between light and shadow, NASA's Cassini spacecraft looks toward the night side of Saturn, where sunlight reflected off the rings has dimly illuminated what would otherwise be the dark side of the planet.
Dione
Saturn's pale, icy moon Dione is enriched by the tranquil gold and blue hues of Saturn in the distance. The horizontal stripes near the bottom of the image are Saturn's rings.
Farewell, Mimas
On Jan. 30, 2017, Cassini bid so long to Saturn's "Death Star"-like moon Mimas.
Mind the gap
Saturn's moon Pan is seen in this color view as it sweeps through the so-called Encke Gap in Saturn's rings. As the lemon-shaped moon orbits Saturn, it always keeps its long axis pointed along a line toward the planet.
Shadowy moon
Jagged-looking shadows stretch away from vertical structures of ring material created by the moon Daphnis in this image taken as Saturn approached its August 2009 equinox.
Titan and Mimas
Cassini captures a mutual event between Titan and Mimas in front of a backdrop of Saturn's rings. This image was snapped shortly before Saturn's largest moon passed in front of and occulted the small moon Mimas.
Dione's closeup
This view of Saturn's moon Dione was taken during a close flyby on June 16, 2015. It was Cassini's fourth targeted flyby of Dione.
Moon's gravity
The gravity of the potato-shaped Prometheus periodically creates streamer channels in Saturn's rings. The moon's handiwork can be seen in the dark channels in this image taken by the Cassini spacecraft.
Dione in transit
Saturn's moon Dione crosses the face of the giant planet in this view, a phenomenon astronomers call a transit.
Icy Enceladus
On Oct. 14, 2015, the Cassini spacecraft snapped a ethereal image of Enceladus' icy north pole.
