NASA has released fresh images of Ceres taken by the Dawn space vehicle . Not only is the point astonishing , but the resolution may serve our understanding of the enigmatic nanus major planet .
Theimageabove is of Haulani Crater . At 34 kilometers ( 21 mile ) across , it is far from the largest volcanic crater on Ceres , but it ’s distinctive as one of the freshest geologic features . It was taken when Dawn was still in its high - altitude map orbit , about 1,480 kilometers ( 920 miles ) above Ceres . Spectacular as this image is , better was still to come . Since then , Dawn has moved into its terminal orbit , 385 kilometers ( 240 miles ) above the surface , from which height it can see aim 35 meters ( 115 animal foot ) across .
Although Haulani ’s brightness make it interesting , the blue color see in the top simulacrum has been heighten . Dawn has detected standardised food color around other young features on Ceres ' control surface .
" Haulani dead exhibit the property we would await from a fresh impingement into the surface of Ceres . The volcanic crater floor is largely free of impacts , and it contrasts sharply in color from older parts of the aerofoil , " saidDr . Martin Hoffmannof the Max Planck Institute for Solar System Research , Germany , in astatement .

Without the color sweetening used for the high - height paradigm , Haulani front less salient , but planetary scientists appreciate the even closer look at the oddly uncoiled lines around the volcanic crater ’s rim , which change by reversal Haulani into a polygon , rather than the orbitual form of most Crater .
The other high spot of the recent set of images is Oxo Crater . Only 10 kilometers ( 6 miles ) across , Oxo is the second brightest physical object on Ceres , after the central area ofOccator Crater , which is so brightHubble detectedthe anomaly before Dawn ’s access .

Most Ceres maps place Oxo near the border , so it is less intimate to non - specialists than some other feature . Besides its luminousness , Oxo has attracted aid from scientists for the large section known as a “ slump , ” where material has fall below the surface . Minerals on the crater floor look to have a dissimilar composition from the residuum of Ceres , prompting considerable pastime in more detailed images .
