Ahuna from Overhead (IMAGE) Arizona State University Caption Dawn's Framing Camera looks down on the fractured summit of Ahuna Mons, tallest mountain on dwarf planet Ceres. The cracks on top suggest Ahuna grew by inflation: icy freezing water pushed up inside the mountain, making a dome. (This image and the following one have the same scale and orientation, and are taken from the Science paper.)
