October 8. Space — a cozy place. If a star explodes or black holes collide anywhere in our part of the Milky Way, they will create huge explosions, deadly gamma rays, X-rays, cosmic rays. Several studies have recently shown a higher power, such as supernova explosions and extreme solar flares can deplete the ozone layer, allowing ultraviolet radiation to penetrate to the surface of the Earth. This is enough to destroy life on earth or in the ocean. "We find that the short gamma-ray burst is even more significant large gamma-ray burst" — said astrophysicist Brian Thomas. The accumulated data collected SWIFT satellite, which catches gamma-ray bursts, the best source for the study of the threat to life on Earth. Short bursts: no more than one second. "Time is not as important as the amount of radiation" — Thomas said. If an explosion occurs inside the Milky Way, then the consequences will be much stronger. The first effect — the destruction of the ozone layer. "Thus, we see a big impact on the ozone layer"
