NASA’s space probe Dawn continues its approach to the dwarf planet Ceres. This allows to send on Earth better and better photographs with greater details of its surface. The previous images were clear enough to make it possible to see some light-colored areas and in particular a really bright one, which had puzzled scientists. A photo taken on February 19 at a distance of about 46,000 km (about 29,000 miles) shows a second bright area close to the one already identified.
