Unusual egzoplanet looks like a comet

For the first time in the history of Astronomy were able to observe. firing atmosphere of the planet by the star around which it revolves. The world of exoplanets GJ 436b, that it has the size of Neptune, is exceptional thanks to an extremely dynamic processes taking place in the atmosphere.

The planet weighs 22 times more than the Earth, is in the constellation Leo, at a distance of about 33 light years, and it looks quite like a Comet, as it pulls behind a giant braid.

Researchers from the University of Warwick have found evidence to confirm the hypothesis that exoplanets that are located close to the host star comes to burn part of the atmosphere by the powerful x-rays coming from celebrities, in this case the red dwarf star GJ 436.

The cloud extending for 15 million kilometers, we can see through exposure to ultraviolet light and x-rays, which were recorded by the Hubble space telescope and the Chandra spacecraft.

Every second from the atmosphere of the planet GJ 436 b escapes about 1000 tons of hydrogen. This means that every billion years the planet loses 0.1 percent of its atmosphere.

So if you live in it any substance, they may sleep as their beloved planet loses all its atmosphere only for tens of billions of years, and so it’s not “will live” even their daily star.

The researchers believe that the same process can be carried out much more sharply on other egzoplanets, where in a short period of time leads to the complete destruction of the atmosphere.
