The dwarf planet is a bizarre, cryovolcanic world. However, the organic deposits discovered on its surface so far are unlikely to originate from its interior.
Data from NASA's Dawn mission, analyzed for the first time, suggest that brine rose from the depths and organic compounds were deposited in Urvara crater.
