Saturn's icy moon Tethys displays a very old impact basin here, just southeast of its giant canyon system, Ithaca Chasma. The large crater has been degraded, or softened, by time and a more recent ...
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, with a resolution of 450 f...

NASA's Dawn spacecraft obtained this image of dark material on hilltops on asteroid Vesta with its framing camera on August 18, 2011. The image has a resolution of about 260 meters per pixel.
Dark Material on Hilltops
Iapetus is a moon of extreme contrasts. The light and dark features give the moon a distinctive "yin and yang" appearance.
Yin and Yang
The shadows of Saturn's rings edge ever farther southward as Saturn creeps towards southern winter (or northern summer). Saturn is now almost exactly halfway between its equinox (August 2009) and ...
Halfway to Southern Winter
Iapetus shows off its puzzling light and dark terrain. Scientists continue to investigate the nature of this moon's surface. See The Other Side of Iapetus to learn more. Lit terrain seen here is ...
This false-color image from NASA's Dawn spacecraft is of the of the giant asteroid Vesta. Scientists are studying image like these to better understand the different materials on the surface.
Different Shades of Vesta (False-Color)
This composite image shows a massive mountain range running just south of Titan's equator. Near the center of the image, the mountain range runs from southeast to northwest. It is about 150 kilomet...
