The new images reveal evidence of the violent past of the dwarf planet Ceres.
Ceres is the largest object found in the asteroid belt. The asteroid belt is located between Mars and Jupiter and it is orbiting the sun.
Researchers believe that the spots reflecting sunlight could be the ice on the surface, but the fact that ice is not stable on an airless body makes this thought invalid, another possible explanation for this could be salts which have remained after the external ice vaporized.
Dawn is orbiting the Dwarf planet form March 6, but couldn’t capture any photo as it was in the shadow region of the planet, but after it has come into the sunlit area it has sent the first photo of the Ceres, the sunlit north pole of the planet.
Dawn is orbiting at 8,400 miles above the surface until May 9, when it will enter into lower orbit of the planet to take high resolution pictures.
Ceres is about 1,000 km across the equator. Researchers believe that this big number is enough for it to have been pulled into a spherical shape, by its own gravity.
Ceres is having a rocky interior and a quarter of its outer portion could comprise of ice, but it is unknown if the rocky interior of ice extends to its core. It could have lower layer of ice, melted to produce an internal ocean, similar to what scientist have found in the satellites of Jupiter, Europa and the satellite of Saturn, Enceladus.
Dawn has taken the image from 14,000 miles from the Ceres North Pole.
Dawn has become the first spacecraft to orbit an extraterrestrial targets. Before orbiting Ceres, Dawn has orbited a giant asteroid Vesta which it studied from 2011 to 2012, in order to gain information on the formation of solar system.
