Sunlight truly has come to Saturn's north pole. The whole northern region is bathed in sunlight in this view from NASA's Cassini spacecraft, late 2016, feeble though the light may be at Saturn's distant domain in the solar system.
This view, taken on Oct. 22, 2016, from NASA's Dawn spacecraft shows the craters Kondos and Jarimba on Ceres. Jarimba is the largest crater, located at left. Above Jarimba, on the left-hand edge of the image, is Kondos.
This frame from an animation from NASA's Dawn spacecraft shows a crater in the northern polar region of Ceres that is partly in shadow year-round, where bright water ice deposits have been observed in several craters.
This frame from an animation shows dwarf planet Ceres overlaid with the concentration of hydrogen determined from data acquired by the gamma ray and neutron detector (GRaND) instrument aboard NASA's Dawn spacecraft.
This view from NASA's Dawn spacecraft shows part of the southwestern rim of Yalode Crater on Ceres. Yalode is one of the largest impact basins on Ceres. A great deal of material has slumped down the walls of the crater. a phenomenon called mass wasting.
This scene captured by NASA's Dawn spacecraft on Oct. 21, 2016, from Ceres' northern hemisphere shows part of the rim of Dantu Crater, at top right. Rao Crater is the largest crater in the bottom left corner of the image.
Dantu Crater on Ceres, at top center, is featured in this image from NASA's Dawn spacecraft taken on Oct. 21, 2016. A small crater located around the 5 o'clock position within Dantu is called Centeotl.
This scene viewed by NASA's Dawn spacecraft on Oct. 20, 2016, from Ceres features terrain near the rim of the large crater named Kerwan, at lower left. A much smaller, fresher crater called Cacaguat is seen in the lower right corner.
Sunlit cliffs tower above Yalode Crater on Ceres in this shadowy perspective view. At 152 miles, Yalode is one of Ceres' largest craters. A fissure called Nar Sulcus is seen just right of center. NASA's Dawn spacecraft took this image on Oct. 19, 2016.
This southern hemisphere scene from dwarf planet Ceres encompasses parts of the craters Mondamin and Darzamat. Mondamin is large crater located in the top half of image, Darzamat is at bottom-right. NASA's Dawn spacecraft took this image on Oct. 19, 2016.
Sintana Crater is seen on the left side of this image of Ceres from NASA's Dawn spacercraft. The crater's central peak casts a shadow over its western flank. At lower right, the rim of Darzamat peeks into view.
In this densely cratered area of Ceres, NASA's Dawn spacecraft spotted Tupo Crater, with its complex, hummocky interior, at center right. A portion of the rim of Darzamat Crater appears with dark shadows at lower left.
Kerwan Crater, at 174 miles (280 kilometers) in diameter is the largest crater that NASA's Dawn has discovered on Ceres. A portion of its jagged rim runs from the top left to bottom center of this image.
This image shows a portion of the northern hemisphere of Ceres, as seen by NASA's Dawn spacecraft. Cozobi Crater is the sharply defined impact feature at top left. At far right is Victa Crater. Abellio Crater is sharply defined crater with a central peak.
