Studies of the surface of the dwarf planet Ceres show evidence of long-postulated “cryovolcanism” in which volcanoes spew cryomagma—slurries of water, ice, and volatiles—rather than lava. Many icy moons, such as Saturn’s Enceladus and Jupiter’s Europa, have features suggesting cryovolcanism. But the identity of that geological activity hasn’t been confirmed. The new data come from NASA’s Dawn spacecraft, which has been orbiting Ceres since March 2015 as it floats in the asteroid belt between Mars . . .
