The radiation emitted by the galaxy, it could kill all bagatellen life that existed at a distance of several tens of thousands of light years from the centre, reports Rus.Media.

Sagittarius A is reducerea, which is located in the center of the milky Way. Likely, it consists of a supermassive black hole, fragments of the latest stars and ionized gazopylevyh of clouds. As the scientists believe, Sagittarius And about 8 billion years ago, there was an active galactic nucleus, which emits x-rays and deep ultraviolet radiation over tens or hundreds of millions of years.

Also, scientists were able evaluated its effect on potentially habitable planets in our galaxy. They came to the conclusion that deep UV rays must “tear off” the atmosphere on objects which are near enough to the center of the milky Way. Therefore, even if the radiation was strongly attenuated by gas and dust surrounding the galactic core, all of earth-like planets that were in Sagittarius And closer than a thousand parsecs (3.2 thousand light years), completely lost their gas envelope by the end of phase activity of the nucleus.

According to the researchers, the radiation emanating from the center of the milky Way, was deadly for complex multicellular organisms that lived on the planets.
