The massive black holes have scary air, but it is thought that they play a vital role in the formation of the stars and therefore in life itself.
The enormous power of the giant hole in the middle of our own galaxy has now been demonstrated by the discovery of two massive "tunnels" formed by huge amounts of deadly hot gas called plasma, coming from the top and bottom of the Milky Way.
The black hole
The latest discovery indicates that these epic bubbles are connected to an area near the black hole by a large plasma that passes through the tubes at temperatures up to 8 million degrees Celsius.
It is unclear exactly why these tunnels were formed, but they are likely to carry the energy produced by the bursting of stars, the formation of new stars or even the energy produced by the black hole itself, where all background to the approach.
"The amount of energy coming out of the center of our galaxy is limited, but it's a very good example of the center of the galaxy," said Mark Morris, professor of astronomy and aeronautics. Astrophysics at the University of California at Los Angeles. We can observe it and try to understand it. "
Pinhole in house
The tunnels are known as Fermi bubbles or "nuclear bubbles" and should be one of the sources of cosmic rays that bombard the Earth, NASA recently announced. It has been observed that one of these bubbles accelerates the particles that then penetrate into space, which indicates that some cosmic rays striking the Earth are produced by huge bubbles.
Our planet is continually exposed to the impact of higher energy particles more active than the particles produced in the NGC 3079. Fortunately, the Earth is protected from all the force of the cosmic rays crossing the atmosphere and the magnetic field.
"The supernova bubbles in NGC 3079 prove that they and their structures could be a source of high-energy molecules called cosmic rays that regularly bombard the Earth," writes NASA.
