Unexpected changes in the bright spots of Ceres

"Astronomers have found unexpected changes in the bright spots on the dwarf planet Ceres. Although it appears as little more than a point of light from the Earth, very careful study of the light from the tiny world shows not only the changes expected as Ceres rotates, but also that the spots brighten during the day and also show other variations. These observations suggest that the material of the spots is volatile and evaporates in the warm glow of sunlight. The scientists, who used the HARPS spectrograph at the European Southern Observatory (ESO) 3.6-m telescope at La Silla in Chile, publish the new work in a paper in Monthly Notices of the Royal Astronomical Society."
