NASA finds dwarf planet Ceres once had global ocean

Ceres may have once had a global ocean - and part of it could still remain, NASA has revealed. The dwarf planet, best known for its strange'alien spots', is seen as being a record of the early solar system. Now, the Dawn mission has found minerals containing water are widespread on its surface. Ceres is 590 miles (950 km) across and was discovered in 1801. It is the closest dwarf planet to the sun and is located in the asteroid belt between Mars and Jupiter, making it the only dwarf planet in the inner solar system.
