Like Jupiter's moon Europa, and Saturn's moons Titan and Enceladus, scientists have speculated that Ceres could be an "Ocean World," meaning that it could have a liquid water interior that could support life. Dawn's findings indicated that the planetoid is too cold in its interior to prevent water from freezing, and any liquid it contains is likely to be concentrated brines. But according to new research by NASA scientists, Ceres may have had the right conditions to support single-celled lifeforms about 2.5 to 4 billion years ago.
