Dwarf planet does hold frozen water
Hidden in deep craters beneath the surface of the dwarf planet of Ceres, there is ice, according to recent research by a team headed by Thomas Platz from the German Max Planck Institutes. Since the spring of 2015, NASA's Dawn satellite has been orbiting the dark, crater-packed Ceres, which is the largest object in the Asteroid Belt between Mars and Jupiter. Images from Dawn reveal a series of craters that are located in permanent shadow at temperatures of -163 C. In such extreme cold, ice can persist for billions of years. The Dawn satellite’s measurements also reveal that at least one of the craters – and probably several others – are full of frozen water.
