Astronomers from the University of Leicester have made pictures of unusual aurora on Saturn, which occurs when a magnetic field of Saturn has a "bombardment" of charged solar particles. Opening researchers are confirming the theory, that auroras on Saturn often arise as a result of a substantial collapse of its "magnetic tail" Just as comets, planets such as Saturn and Earth have a "tail" - so-called magnetic loop or tail of the magnetosphere. At a time when particularly strong stream of solar particles "hits" Saturn, the planet's magnetic loop can be compressed, resulting in causing disturbances in its magnetic field. These disturbances are the reason that there are "aurora " About the same things happen on Earth. Researchers at the University of Leicester observed, as it occurs on Saturn from April to May 2013, the three-year program of observations by Space Telescope Hubble. Their discovery was made by publication in Geophysical Research Letters.The ultraviolet images made by supersensitive camera Telescope Advanced Camera for Surveys, shows the moments when Saturn's magnetic field is exposed to particle fluxes from the Sun .Due to the nature of Saturn's atmosphere, its auroras glow brightly in the ultraviolet part of the electromagnetic spectrum.Scientists were able to take pictures during a very dynamic "light show". Some flashes of light streaking over the polar regions of Saturn, traveling at a rate three times greater than the speed of rotation of the gas giant. With the help of two spacecrafts, managed to make a 360-degree picture of Saturn's auroras: both the north and the south pole of the planet. On Earth an observers can see the aurora as a green veil of light, glowing with bright red tops. Cassini camera shows us a similar picture auroras on Saturn, only the red color here at the bottom and top is purple, VIDEO:
