This composite image shows a mosaic of the European Space Agency's Huygens probe landing site, as seen by the descent imager/spectral radiometer on the Huygens probe. The mosaic is overlaid on a C...

Numerous small, bright spots appear on asteroid Vesta, as seen in this image from NASA's Dawn spacecraft. This region is just north of the equator, to the west of Marcia crater.

The Cassini spacecraft and Huygens probe begin their seven-year journey to the ringed planet. The successful launch of Cassini aboard a Titan IVB/Centaur occured at 4:43 a.m. EDT, October 15, 1997.

Bright, wispy fractures streak across Dione's trailing side. Following the Voyager flybys of the early 1980s, scientists considered the possibility that the streaks were bright material extruded by...

This image of Ceres, taken by NASA's Dawn spacecraft, shows a giant, ancient impact crater with smaller craters in its interior. The large crater shows partial terracing on its southeast rim, where...

Janus is spotted over Saturn's north pole in this image while Mimas' shadow glides across Saturn. Janus is the faint dot that appears just above Saturn's north pole. Mimas' shadow can be seen i...

This image, taken by NASA's Dawn spacecraft, shows a portion of the southern hemisphere of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image was taken on Sept. 20, 2015...

Phoebe delivers on its promise to reveal new wonders to Cassini by showing probable evidence of an ice-rich body overlain with a thin layer of dark material. The sharply-defined crater at above cen...

This interesting vortex in Saturn's atmosphere is surrounded by a halo of bright clouds that extend away toward the east and west. Storms like this one seem to be bright at all wavelengths at which...

Color Pluto, July 13, 2015.

The Encke Gap moon, Pan, has left its mark on a scalloped ringlet of the Encke Gap. The moon creates these perturbations as it sweeps through the 325-kilometer (200-mile) gap in the A ring. Three ...

The colorful globe of Saturn's largest moon, Titan, passes in front of the planet and its rings in this true color snapshot from NASA's Cassini spacecraft. The north polar hood can be seen on Tita...

The cratered and cracked disk of Saturn's moon Dione looms ahead in this mosaic of images taken by Cassini on Oct.11, 2005, as it neared its close encounter with the icy moon. The images used for ...

Several spiral density waves in Saturn's A ring are seen in this detailed view. There is a grainy texture visible between the brightness peaks in the most prominent wave. Scientists think the grain...

For an Earth observer on May 3, 2005, the Cassini spacecraft appeared to pass behind the rings, then Saturn, then the rings again (the red line). The discovered harmonic structure was found on both...

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...
