The Changing Bright Spots of Ceres: New Evidence for Geological Activity?

Artist’s illustration of the brights spots Occator crater and elsewhere, based on a detailed map of the surface compiled from images taken from NASA’s Dawn spacecraft in orbit around the dwarf planet Ceres. New observations show that the bright spots change in brightness from day to night, suggesting that they change under the influence […]
