This image of Domna AV-L-17, from the atlas of the giant asteroid Vesta, was created from images taken as NASA's Dawn mission flew around the object, also known as a protoplanet.
+ Full Res This image was taken by NASA's Cassini spacecraft on April 14, 2012. The camera was pointing toward Enceladus at approximately 75,067 miles (120,808 kilometers) away. This image has n...

Saturn's northern hemisphere is seen here against its nested rings. This view from the Cassini spacecraft looks toward the unilluminated side of the rings from about 30 degrees above the ringplane...
Off the shoulder of giant Saturn, a bright pinpoint marks the location of the ring moon Atlas (image center). Shadows cast by the C ring adorn the planet at upper right. The thin boundary of Satur...

The Cassini spacecraft looks up from beneath the ringplane to spy Atlas hugging the outer edge of the A ring, above center. The image was taken in visible light with the Cassini spacecraft narrow-...
In Greek mythology, Dione was the daughter of Tethys, so we should perhaps not be surprised to see the two eponymous moons together.

Researchers from NASA's Dawn mission have composed the first comprehensive views of the north (left) and south pole regions (right) of dwarf planet Ceres, using images obtained by the Dawn spacecra...
First Complete Look at Ceres' Poles
This image, taken by NASA's Dawn spacecraft, shows a portion of the northern hemisphere of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image was taken on Sept. 21, 2015...
Dawn HAMO Image 41
Many features in Saturn's rings are thought to be induced by the gravity of the planet's moons. This view shows two different kinds of waves that are thought to be produced by different moon-relate...
Two Kinds of Wave
The A and F rings are alive with moving structures in this Cassini spacecraft view. Graceful drapes of ring material created by Prometheus are seen sliding by at left, while clumpy ringlets slip th...
Streamers and Clumps
Epimetheus is one of Saturn's "co-orbital moons" because it shares nearly the same orbit as Janus at a distance of approximately 151,000 kilometers (94,000 miles) from Saturn. Epimetheus is 116 kil...
Titan emerges from behind Saturn, while Tethys streaks into view, in this colorful scene. Saturn's shadow darkens the far arm of the rings near the planet's limb. Titan is 5,150 kilometers (3,200 ...
