Another star system was sterilized by any possible life
From the report Eike Guenther of German Observatory Karl Schwarzschild presented at a scientific conference held in the framework of the European Week of Astronomy and Space Science, it became known that a powerful X-ray radiation, which arose as a result of the outbreak on the AD Lion Star (aka Gliese 388), could " blow "the ozone layer to any zemplepodobnoy planet which hypothetically may be in the system.
Astronomers have known about the presence of nearly 4,000 planets orbiting a variety of stars. In this case quite a considerable number of them are Earth-like planets, which are located within the so-called inhabited areas, where the surface can be held favorable temperature suitable for the existence of water in liquid form. However, the majority of candidates zemplepodobnyh wrapped around the star class red dwarfs.
These stars are much smaller and cooler than our Sun, and therefore to create suitable conditions for life on the planet need to be located close to such stars. The problem is that despite the generally calm temperament, red dwarfs are able to from time to time to create a very powerful X-ray emissions, accompanied by coronal mass ejections. Since the "habitable" planets red dwarfs are relatively close to the star, such outbreaks can pose a serious danger to life, appearing on their surface. Especially powerful coronal mass ejections can simply "blow off" the planet's atmosphere. To find out more precisely the possible effects of such emissions, Gunter team conducted monitoring of red dwarfs, in which such emissions could occur. And in February 2018 scientists actually recorded one such flash on AD Leonis star known as Gliese 388 (flash itself, of course, occurred much earlier). The star is located 16 light-years away and has 3 million miles away from you (about 15 times closer than Earth is to the Sun), the giant planet. Scientists are not yet sure, but it is possible that within this system may be other planets, also located in the habitable zone, however, to see them through modern devices is not possible.
The first observations showed that, in contrast to solar flares, flash on AD Leonis was not accompanied by coronal mass ejections. Therefore, the atmosphere of the nearest planet to the star and the more distant potentially habitable planets should not have to suffer.
However, further analysis of the data showed that the flash accompanied a powerful X-ray radiation. From the constructed model scientists indicated that such radiation would be easily broken through ozone potentially habitable planets, the thickness of which is comparable to the ozone layer of the earth, and would destroy life on its surface. Moreover, this radiation could destroy much of the ozone layer in just two years. Thus, if a hypothetical planet AD Leonis system and was a life she could only survive in the oceans. And it is doubtful. In the future, the research team Gunter collected on the basis of new observations make their model is more detailed. Some scientists have suggested that very high radiation emission can deprive any planet 94 percent of its ozone layer in two years, which will lead to the death of all living things. If this statement is true, then count on the opening of "Earth 2.0" from the red dwarf to be premature.
