You thought those bright spots on dwarf planet Ceres were cool? That was only the half of it. Ceres is also covered in dark spots, craters that — because of their position — never see the light of day. Now, astronomers have discovered that at least one and perhaps many of these shadowy regions are filled with water ice.
