The sun poses a serious threat for Earth: "flashes murderers"


Astronomers said that the Sun poses the big hidden threat
of
for Earth sudden superflashes of stars are guilty Of everything.

So, the group of scientists of the universities of Kyoto, Hiy, Washington, the University of Colorado Boulder, National astronomical observatory of Japan and Leiden University studied flashes murderers.

According to the expert opinion, in recent years such flashes becomes more and more. Why, scientists are at a loss with the answer so far.

of the Star throw out from time to time very powerful balls of fire which can be seen for hundreds of light years. Until recently researchers assumed that such "explosions" occurred generally on stars which are much younger than Earth.

However a new research showed that flashes can happen also on stars as our Sun - old and inactive.

If similar flash occurs in the Sun, then it threatens Earth with nothing good. Emission of energy will cause the real chaos on our planet. it is difficult to

of the Consequence to foresee. The flash in the Sun can damage work of satellite communication and power supply systems, and can destroy all mankind.

calms A little the fact that by calculations of scientists, such destructive flashes in the Sun happen once in several thousands of years.

"Results of our research have to become a disturbing call for existence of life on Earth. If the similar superflash happens in the Sun, then Earth, most likely, will appear on the way of a wave of high-energy radiation. Such explosion can break operation of electronics on all globe, causing universal blackout", - the leading author of work Juta Notsu warned.

As was reported earlier, scientists found the fastest object in the Galaxy. It is the largest and bright star This Kiel that threw out the heated matter bunches dispersed to fantastic speed in 20 thousand kilometers per second, or 6% of the speed of light two centuries ago.

Nathan Smith from the university of Arizona in Tucson (USA) told that similar speeds are characteristic of flashes supernew when explosion destroys a star completely. As in this case similar did not occur, there has to be a process which downloaded huge amounts of energy in a star for very short time.

This Kiel has unusual history. For the first time on the map of the sky this star was marked by the English astronomer Edmund Galya in 1677. Throughout the 18th century and the beginning of the 19th century brightness of this star periodically increased and decreased.

B its brightness began to grow 1827 quickly, having reached a maximum in April, 1843. At that moment it eclipsed all other stars in a firmament, except Sirius located about one thousand times closer to Earth, than This Kiel, removed from us on 7800 light years.

B 20 a century of observation of a star proceeded and showed that it represents extremely exotic double system consisting of the largest star of the Galaxy weighing 120-150 Sun and it "небольш
