Ice Volcanoes May Have Erased Craters on Dwarf Planet Ceres

Ice volcanoes on Ceres might help solve the mystery of why large craters seem to be missing on the dwarf planet's surface, a new study shows. Large portions of Ceres' surface are "saturated" in craters that are about 37 miles (60 kilometers) wide or smaller, likely created by meteorites crashing into the dwarf planet's surface, according to the new study. Prior work that analyzed pockmarked Vesta, the second largest asteroid in the asteroid belt, suggested that Ceres should have at least si
