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.
The Uranian magnetic field is more expansive than previously thought, according to newly analyzed data from Voyager 2, making it easier to search for moons with oceans.
