This image, taken by NASA's Dawn spacecraft, shows a portion of the northern hemisphere of dwarf planet Ceres from an altitude of 2,700 miles (4,400 kilometers). The image, with a resolution of 1,4...

This image of Justina AV-L-29, 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.

This unprocessed image was captured by NASA's Cassini spacecraft during its Nov. 21, 2009 flyby of Saturn's moon Enceladus. It shows the moon's south polar region, where jets of water vapor and oth...

Titan's atmosphere makes Saturn's largest moon look like a fuzzy orange ball in this natural color view from the Cassini spacecraft. Titan's north polar hood is visible at the top of the image, an...

This colorized mosaic from NASA's Cassini mission shows the most complete view yet of Titan's northern land of lakes and seas. Saturn's moon Titan is the only world in our solar system other than E...

The northern hemisphere of Saturn's moon Dione is seen in this polar stereographic maps, mosaicked from the best-available clear-filter images from NASA's Cassini and Voyager missions. This map is...

The small moon Pan casts a short shadow on Saturn's A ring in this image taken as the planet approached its August 2009 equinox. Pan (28 kilometers, or 17 miles across) orbits in the Encke Gap of ...

This image from NASA's Dawn spacecraft shows linear grooves and ridges in Vesta's regolith, located in Vesta's Tuccia quadrangle, in asteroid Vesta's southern hemisphere.

This view shows the unlit side of Saturn's splendid rings made visible by sunlight filtering through the rings from the lit side. Light from the illuminated side of the rings brightens the night si...

Fractures on the surface of Enceladus record a long and complex history of tectonic activity. Many of the geologically youngest fractures define remarkably systematic patterns relative to Enceladus...

This image of Ceres is part of a sequence taken by NASA's Dawn spacecraft on May 4, 2015, from a distance of 8,400 miles (13,600 kilometers).

This map of the south polar region of Saturn's moon Enceladus shows the correlation between jet sources identified in Cassini imaging data and hot spots on the surface located by the composite infr...

Intricate undulations and swirls within the banded atmosphere of Saturn give scientists clues to the processes occurring there. The lower part of the image shows the characteristic billows that fo...

The moon Tethys stands out as a tiny crescent of light in front of the dark of Saturn's night side. Tethys (1,062 kilometers, or 660 miles across) can be seen above the ringplane on the far right ...

Map projection of Charon, the largest of Pluto's five moons, annotated with its first set of official feature names.

This image was taken on March 09, 2013, and received on Earth March 10, 2013, by NASA's Cassini spacecraft. The camera was pointing toward Rhea at approximately 39,072 miles (62,880 kilometers) awa...

This picture from NASA's Dawn spacecraft shows craters in the northern hemisphere of Ceres. The large crater at lower left displays several bright streaks on its walls.

Hyperion is one of the smaller of Saturn's main satellites, is irregular in shape, about 400 by 250 by 240 kilometers (250 by 160 by 150 miles), and is noted for its odd scarp system. Scarps like t...

The battered features of the moon Rhea, seen at low phase, appear washed out by the sun. This view looks toward the Saturn-facing side of Rhea at a sun-Rhea-spacecraft, or phase, angle of 15 degre...

The soft appearance of Dione's wispy terrains belies their true nature. They are, in fact, complex systems of crisp, braided fractures that cover the moon's trailing hemisphere. (See Dione's Surpr...

Clouds near the boundary of day and night on Saturn show unusual three-dimensional structure in this Cassini view. At this location on the planet, the Sun is at a very low angle, causing vertical r...

Atlas joins other moons casting shadows on Saturn's rings as the planet approaches its August 2009 equinox. Atlas (30 kilometers, or 19 miles across) orbits in the Roche Division between the A rin...

This image shows infrared views of two craters,Bellicia (left) and Arruntia (right), at the giant asteroid Vesta that NASA's Dawn mission has found to sport the mineral olivine.

This color photo of Neptune's large satellite Triton was obtained on Aug. 24 1989 at a range of 530,000 kilometers (330,000 miles).
