On Ceres astrophysicists discovered the ice volcano

Dwarf planet Ceres is the largest celestial body between the orbits of Mars and Jupiter, was again the centre of attention of astronomers. Professionals working within the mission, Dawn, introduced in the prestigious journal Science a series of studies on object in space. One of the most curious discoveries made by the experts, was that on the planet there is a so-called cryovolcanism. This volcano was the largest mountain on the dwarf planet.

The cryovolcanism observed on celestial bodies, where he established an extremely low ambient temperature. In essence, cryovolcanism is not too different from our usual worldly volcanoes, but they do not spew molten rock, and the so-called Krilova, often a mixture of liquid ammonia, liquid methane, liquid water and gaseous and other impurities, which vary depending on the space object, which occurs eruption.

On Ceres traces of cryovolcanism found on dome-shaped mountain called the Sea of Mons. How figured out the experts, the eruption of the cold salt water and was the reason that this mountain appeared. The specialists claim that formed the Sea of Mons is a relatively new study showed that it is “younger” than the surrounding impact craters.

Experts do not exclude that processes of cryovolcanism are behind the advent on Ceres mysterious shining spots, has long been a cause of interest not only to planetary scientists, but many people, in General, far from science. Also open to some extent may shed light on some other mysteries surrounding the planet, and to serve as proof of certain earlier assumptions of scientists.

In particular, the version about the eruption of cryovolcanism in good agreement with the earlier assumption about the lakes of liquid salt water liquid salt water in the subsurface of Ceres, and also helps to explain how this water falls onto its surface. In addition, geological evidence of activity on Ceres help to explain why there are no really big craters.

Ceres was discovered in 1801 and named after the Roman goddess of fertility. 27 September 2007 it was launched space station (ISS), and in 2015 on the images of this research probe was first discovered mysterious white spots on the surface of the planet. Initially, concerning their origin were put forward many versions, including the most fantastic. Later scientists have suggested that the spots may be ice, and a little while later as the cause of unusual brilliance were called hydrated magnesium sulfate.
