    A recently discovered solitary ice volcano on the dwarf planet Ceres may have some hidden older siblings, say scientists who have tested a likely way such mountains of icy rock – called cryovolcanoes – might disappear over millions of years. NASA’s Dawn spacecraft discovered Ceres’s 2.5-mile tall Ahuna Mons cryovolcano in 2015...
