Ice, Ice Everywhere, says New Study on Ceres

"On Ceres, ice is not just localized to a few craters. It's everywhere, and nearer to the surface with higher latitudes. These results confirm predictions made nearly three decades ago that ice can survive for billions of years just beneath the surface of Ceres. The evidence strengthens the case for the presence of near-surface water ice on other main belt asteroids."

"These studies support the idea that ice separated from rock early in Ceres' history, forming an ice-rich crustal layer, and that ice has remained near the surface over the history of the solar system. By finding bodies that were water-rich in the distant past, we can discover clues as to where life may have existed in the early solar system."
