Great Dark Spot
This image of a bright-rayed crater on giant asteroid Vesta was taken by the framing camera aboard NASA's Dawn spacecraft. The crater is about 2 miles (3.5 kilometers) in diameter and impacted on t...

The Cassini spacecraft looks down on the north pole of Mimas and sees the moon's cratered trailing hemisphere. The moon's north pole lies on the terminator about a quarter of the way inward from t...
Trailing Hemisphere Craters
Two frigid moons, Rhea and Enceladus, shine in reflected light from Saturn. In such low light and at great distance, Rhea's cratered surface looks deceptively smooth. Light from the distant Sun cre...
This view of the unlit side of Saturn's rings captures the small shepherd moon Pandora as it swings around the outside of the F ring. The F ring displays a few discrete bright clumps here. This vi...

Pan may be small as satellites go, but like many of Saturn's ring moons, it has a very visible effect on the rings.
Where the Small Moon Rules
NASA's Dawn spacecraft took this image on Feb. 4, 2016, showing a double impact feature at high northern latitudes on Ceres, just south of the large crater named Ghanan.

Saturn's moon Epimetheus moves in front of the larger moon Janus as seen by the Cassini spacecraft. This view looks toward the leading hemispheres of Epimetheus (113 kilometers, or 70 miles across...

A variety of surface ages is revealed in this 16-image mosaic taken during Cassini's first close flyby of Enceladus, on Feb. 17, 2005. This mosaic shows the trailing hemisphere of Enceladus -- the...

Seen within the vast expanse of Saturn's rings, Prometheus appears as little more than a dot.
A Dot Does a Lot
This view from NASA’s Dawn mission shows the floor of Ceres’ Juling Crater. The crater floor shows evidence of the flow of ice and rock, similar to rock glaciers in Earth’s polar regions.

Powerful forces ripped apart the surface of Tethys at some time in the deep past, creating the incredible canyon system of Ithaca Chasma. This view shows nearly the full extent of Ithaca Chasma, wh...
This remarkably clear view from that flyby shows the moon's characteristically dark mid-latitudes, and more southern terrain than the Cassini spacecraft has usually been able to glimpse. This was ...
Cassini prepared for its rendezvous with Dione on Oct. 11, 2005, capturing the brilliant, cratered iceball in front of its shadow-draped planet. The terrain seen here becomes notably darker toward...

Why does Saturn look like it's been painted with a dark brush in this infrared image, but Dione looks untouched?
This computer-enhanced photo of Saturn, taken November 13, 1980, by Voyager 1, shows Saturn's rings and their shadows against the lighted crescent of the planet. The photo was taken from a distance...
NASA's Dawn spacecraft obtained these images with its visible and infrared instrument of asteroid Vesta. The top image is a simulated true-color picture of the asteroid's surface.
