Planetary scientists have suspected the existence of lakes of liquid water on Ceres


Data collected in the framework of the space mission Dawn, has allowed scientists to make the assumption that in the depths of the dwarf planet Ceres may be small lakes of liquid salt water. Also, professionals were able to clarify the composition of the substance at the bottom of craters Ceres, which with its unusual glitter for quite some time attracted the attention of both professionals and people interested in astrophysics.

Analyzing images in the visible and infrared ranges, the experts came to the conclusion that on the surface of Ceres and, particularly, its “luminous” craters contains a considerable amount of carbonate of sodium, mixed with silicates. Probably, these substances are trapped on the surface of the dwarf planet from its bowels as a result of collision with asteroids, experts suggest.

A study on the possibility of the existence of liquid lakes on Ceres, the scientists presented in the journal Nature Geoscience. In turn, the work on the craters of the dwarf planet, published in the scientific journal Nature.

Nature bright spots on Ceres remained a mystery for a long time. The first images taken by Dawn probe, which can be seen brilliant point appeared in 2015 and was initially put forward a variety of versions of their origin, including the most fantastic. Later scientists began to lean toward the probability that Shine on dwarf planet may be ice, but after some time the primary version was that the real reason for the unusual luster are salt — hydrated magnesium sulfate.

Ceres is the largest known space object in the asteroid belt between the orbits of Mars and Jupiter and the nearest to the Sun dwarf planet. A heavenly body was discovered in 1801 and named after the Roman goddess of fertility. Some time Ceres was considered a “normal” planet, however, were classified as dwarf planets by the International astronomical Union on 24 August 2006. Station Dawn was launched to Ceres on 27 September 2007 and reached its orbit on March 6, 2015.
