NASA’s Dawn spacecraft captured this close-up of Occator, a crater on the dwarf planet Ceres. About 90 kilometers (60 miles) across, it contains the brightest spots on the dwarf planet. Mission scientists hope to solve the mystery of the spots with closer observations.
Launched in 2007, Dawn arrived at Ceres in March 2015. About 940 kilometers (584 miles) wide, Ceres is the largest object in the asteroid belt between Mars and Jupiter. It’s believed to have a rocky core, a thick icy mantle, and maybe an ocean beneath an icy crust.
