And then there was one: Ceres' disappearing ice volcanoes

Earth has numerous volcanoes, both active and extinct — some of which continue to tower over landscapes long after they finished erupting. On the chilly dwarf planet Ceres, however, scientists have identified just a single volcano — an ice-erupting cryovolcano — raising questions about whether others ever existed there and, if so, what happened to them. In a new study, researchers suggest that Ceres has likely had other volcanoes, but that, over time, their icy slopes have been flattened beyond recognition.
