Get the Closest Look Yet of Ceres' Cratered Surface
The brightest spots on dwarf planet Ceres are seen in this image taken by NASA's Dawn spacecraft on June 6, 2015. This is among the first snapshots from Dawn's second mapping orbit, which is 2,700 miles (4,400 kilometers) in altitude. The resolution is 1,400 feet (410 meters) per pixel. Scientists are still puzzled by the nature of these spots, and are considering explanations that include salt and ice.
