American Dawn probe, launched by NASA in late September 2007, sent high-quality photos of the surface of the dwarf planet Ceres, which show unusually bright spots. Their origin remains a mystery, according to one hypothesis, the source of illumination may be cryovolcanoes activity.

New images were obtained with an orbital altitude of 4.4 thousand kilometers. The region with glowing spots located in the crater of a width of about 90 kilometers. New data will allow scientists to determine the source of the stains. the Bright spots make Ceres a unique object among all that we observe in the Solar system" is described in NASA. According to the representative of the Agency, scientists continue to search for explanations of the glow.

Astronomers believe that the source of illumination may be ice, but it is possible that deposits of salt. In the near future it is expected the emergence of new images with even higher resolution and taken from different angles.
