Artist's concept

This image, taken by NASA's Dawn spacecraft, shows the surface of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image, with a resolution of 450 feet (140 meters) per pixe...

This processed image, taken Jan. 13, 2015, shows the dwarf planet Ceres as seen from the Dawn spacecraft. The image hints at craters on the surface of Ceres. Dawn's framing camera took this image a...

This image from NASA's Dawn spacecraft showing the northern part of Hanami Planum on Ceres honors the Japanese cherry blossom festival, or 'Hanami,' a long-standing Japanese tradition of welcoming ...

+ View Full Res + Original PIA09217, July 2007 This image was obtained by Cassini's radar instrument during a flyby on April 10, 2007. The radar antenna was pointing toward Titan at an altitude...

This colorized image of Europa is a product of clear-filter grayscale data from one orbit of NASA's Galileo spacecraft, combined with lower-resolution color data taken on a different orbit.

This image from NASA's Dawn spacecraft shows a large crater with several smaller craters at the edge on the giant asteroid Vesta. Rough texture in the crater wall at far right may be the underlying...

Odysseus Crater, with a size of epic proportions, stretches across a large northern expanse on Saturn's moon Tethys.

This view is part of a montage of images from the NASA Cassini and Voyager missions shown in D Ring Revelations. The inset image from the montage is presented here by itself and in its original ori...

NASA's Dawn spacecraft looked northward toward the limb of Ceres to capture this scene, with Rao Crater (7 miles, 12 kilometers) at bottom.

The Cassini spacecraft captures here one of its closest views of Saturn's ring-embedded moon Daphnis. This image was taken July 5, 2010, at a distance of only about 75,000 kilometers (47,000 miles...

This image from NASA's Dawn spacecraft of asteroid Vesta shows Lepida crater, located in Vesta's Floronia quadrangle, in Vesta's northern hemisphere.

The Cassini spacecraft acquired this view of Rhea's leading hemisphere near "opposition," or with the Sun almost directly behind the camera. Under this geometry, topography appears less rugged be...

An enhanced close-up view shows at least two distinct jets spraying a mist of fine particles from the south polar region of Enceladus. The particles in the plume scatter sunlight most effectively a...

Ceres' surface shows evidence for different types of flows that indicate the presence of ice in the regolith (as described in PIA21471).

A new Mars impact crater that formed between July and September 2018.

A pair of moon shadows and a series of spokes adorn this ring image taken about a month after Saturn's August 2009 equinox. The shadow of the moon Janus stretches across the middle of the image. T...

North Atlantic phytoplankton bloom off the coast of Iceland, June 24, 2010.

This image from NASA's Dawn spacecraft shows a close up of part of the rim around the crater Canuleia on the giant asteroid Vesta. Canuleia, about 6 miles (10 kilometers) in diameter, is the large ...

Saturn's moon Prometheus casts a shadow near a streamer-channel created by the moon in the thin F ring in this image taken about a month after the planet's August 2009 equinox.

This view, taken on Oct. 22, 2016, from NASA's Dawn spacecraft shows the rim of Yalode Crater on Ceres at upper left. Yalode is one of the largest impact basins on Ceres.

The real jewels of Saturn are arguably its stunning collection of icy moons. Seen here with the unlit side of the rings are Titan (5,150 kilometers, or 3,200 miles across at right), Tethys (1,071 k...
