NASA spots more mysterious bright spots on Ceres

Washington: New images of Ceres from NASA's Dawn spacecraft has provided more visible images of mysterious bright spots and also revealed a pyramid-shaped peak towering over a relatively flat landscape. Dawn has been studying the dwarf planet Ceres, the largest object in the main asteroid belt between Mars and Jupiter, in detail from its second mapping orbit, which is 4,400 km above Ceres.

A new view of its intriguing bright spots, located in a crater 90 km across, shows even more small spots in the crater than were previously visible, the US space agency said. At least eight spots can be seen next to the largest bright area, which scientists think is approximately nine kms wide. Although ice and salt are leading candidates that could explain these spots, scientists are considering other options, too.

"The surface of Ceres has revealed many interesting and unique features. For example, icy moons in the outer solar system have craters with central pits but on Ceres central pits in large craters are much more common," said Carol Raymond, deputy principal examiner for the Dawn mission, NASA.
