COVER The surface of the dwarf planet Ceres, as seen by NASA's Dawn spacecraft. On the left is the pale mountain Ahuna Mons, a 4-kilometer-high cryovolcano formed by an eruption of ice from beneath the surface. On the right is an unnamed 17-kilometer-diameter crater. Orbital imagery was combined with a digital terrain model to create this perspective view. See aaf4286, aaf4219, aaf4759, aaf4332, aaf4279, and aaf3010.
