NASA finds ancient ocean remnants at dwarf planet Ceres
NASA's Dawn mission at dwarf planet Ceres, lying between Mars and Jupiter, has found hydrated minerals over its surface, suggestive of ancient oceans on the planet. The study suggests Ceres' crust represents most of the ocean while a softer layer beneath the crust, could be residual liquid's signature. Previous studies have estimated Ceres holds more water than Earth by weight.
