The intrigue surrounding Ceres continues to deepen as a NASA probe gets closer to the dwarf planet. The new photos of Ceres from NASA's Dawn spacecraft, which is scheduled to arrive in orbit around Ceres on the night of March 5, reveal that a puzzling bright spot on the dwarf planet's surface has a buddy of sorts. Dawn took the new images on Feb. 19, when it was about 29,000 miles (46,000 kilometers) from Ceres — still too far away to give scientists a good look at the peculiar spots. "The brightest spot continues to be too small to resolve with our camera, but despite its size, it is brighter than anything else on Ceres," Andreas Nathues, lead investigator for the framing camera team at the Max Planck Institute for Solar System Research in Gottingen, Germany, said in the same statement. "This is truly unexpected and still a mystery to us."
