The group of astronomers from LeicesterUniversity (Britain) collected the proofs on which [ad name=”Google Adsense-3 11″] the rings of Saturn daily lose huge volumes of substance, which drops out in a planet ionosphere. It is known, that rings of a planet consist both of submillimetric particles of ice, and of huge blocks with size in kilometers. If large fragments of ice move in rings on Keplerian orbits, movement of small particles if they receive rather big electric charge a bit different. Like particles of a solar wind in near-earth space, these micro particles of ice are capable to leave the plane of rings and, being cast over power lines of a magnetic field, to travel to Saturn. If this is so, scientists argued, a certain stream of weight has to drop out constantly at different widths of the atmosphere of Saturn. To see a stream of the frozen water they didn’t hope, but it was succeeded to notice characteristic signs of this process. Scientists noted, that this sleet drops out in a planet ionosphere generally at the widths from 25 to 60 degrees, and as a whole such loaded precipitation covers from 30 to 43% of a atrmosphere of Saturn. For this moment it is unclear, whether water reaches the planet atmosphere in the form of ions or in the form of the submillimetric loaded particles of ice. The main result is not in an assessment of evolution or time of life of rings, and that we see in the atmosphere of Saturn. For a long time there was considered, hat at some widths density of electrons has to be higher, than the observable. It appeared, that water causes a recombination of electrons, reducing their density According to the astronomers, now it is necessary to understand, whether causes a constant stream of particles of rings heating or cooling of the top areas of an ionosphere. Researchers note, that they managed to reveal for the first time ionosphere interaction with substance of rings and to understand how give the substance on a planet separate rings A, B and C.
