Betelgeuse is a few thousand years will crash into the wall of dust

One of the brightest stars in the sky — red supergiant Betelgeuse — a few thousand years will face a mysterious interstellar structure — "dusty wall", according to the European infrared telescope "Herschel."

Betelgeuse — a star in the constellation of Orion, which is on the "right shoulder" star Hunter, is one of the brightest stars in Earth's sky, its distance is about 600 light years, and the apparent magnitude — about 0.42 (magnitude of the brightest star, Sirius, is minus 1.46).

Unlike the Sun, the stars of "middle age", Betelgeuse is in the last stage of stellar evolution — red supergiant stage. At this stage, the stars that have exhausted their supply of hydrogen "fuel", dramatically expanding and start to dump stuff in the outer shells of the open space.

In the pictures, "Herschel" were found numerous "arc" around Betelgeuse — the gas-dust "bubble" formed by interstellar matter and dropped the shell. Before his star on the infrared images visible shock front, as the light moves through the interstellar medium at a speed of about 30 kilometers per second, according to the website of the European Space Agency.

However, more in the way of Betelgeuse seen mysterious "wall." "The linear structure may be the edge of interstellar clouds, illuminated Betelgeuse or interstellar filaments (thread-like form), whose origin may be associated with the galactic magnetic field," — said in an article published by astronomers in the journal Astronomy & Astrophysics.

They estimate that over 5000 years to this "wall" will face a gas "bubble" around Betelgeuse, a star itself — in another 12.5 thousand years.
