Washington, June 30. More than 130 bright spots on the surface of the dwarf planet Ceres may well be lakes of liquid salt water. This hypothesis vyidvinuli the mission Dawn team zapodozrevshey, the existence of small salty lakes Ceres. The brightest spot is located in the crater Okkator.
The publication of new research in the journal Nature and Nature Geoscience. experts shared data collected in the visible and infrared spectrograph Dawn automatic station. According to scientists, they indicate the presence on the surface of the celestial body sodium carbonate mixed with silicates. On the surface of Ceres they came from the depths of the dwarf planet after a collision with an asteroid, scientists believe.
In addition, geophysicists have assumed that most of the craters with spots on Ceres are too deep to consist entirely of ice. Thus, according to scientists, the composition of a subsurface layer of Ceres by 30-40% consists of water ice, and by 60-70% -. Of silicate rocks with inclusions of hydrated salts and clathrates
