Blog Post Image: Origin of Moon’s ‘ocean of storms’ revealed

Ocean of storms. A topographic map of the Moon (low elevations in purple, high in red) shows extensive lava flows in Oceanus Procellarum. New data from the GRAIL spacecraft suggests the region was formed by ancient volcanic activity, not by a large impactor as had long been suspected. The image was rendered with data from NASA’s Lunar Reconnaissance Orbiter and Lunar Orbiting Laster Altimeter. Image credit: Jay Dickson/Brown University
