MOSCOW, February 10 – RIA Novosti . Radio waves have helped astrophysicists first look at what is behind the Milky Way, and found him hundreds of previously unknown galaxies in large structures of the universe – the so-called “Great Attractor”, according to an article published in the Astronomical Journal

<. p> “the Milky Way – a beautiful galaxy, and it is interesting to explore, but it completely obscures our view of those galaxies, which are followed by our observations helped it to make and find the answer to that, what is the reason the phenomenon of celebrity.” Great Attractor ” about the impact that the expansion of the universe, scientists say 70 years of the last century, “- said Lister Staveley-Smith (Lister Staveley-Smith) from the University of Western Australia in Crawley

Staveley-Smith and his colleagues have uncovered the mystery. why the Milky Way “inhibited” Great attractor, finding him a big, invisible and close to our component, which they called the “Great Wall”, observing the fluctuations in the emission of neutral hydrogen in the intergalactic medium of the southern part of the galaxy with the help of Australian Radio telescope Parkes.

it tells the scientist in the mid 70′s of the last century, astronomers have discovered that the Milky Way and its neighbors are not removed, as predicted by the theory of the expanding universe and are moving towards some other galaxies at a rate of 2 million kilometers per hour.

This movement has been observed in the 90s and 2000s, was associated with the so-called “Great Attractor” – potentially the largest objects in the universe, a giant cluster of galaxies that extends to nearly half of the sky of the southern hemisphere Earth. Although there is a clear correlation, the researchers could not explain why this group of galaxies “pushes” the Milky Way in the direction in which it moves.

The observations carried out with the help of Parkes telescope, helped find the cause of this movement – a group of over 880 galaxies, invisible to us, located outside the Milky Way at a distance of about 250 million light-years. At this point presumably is part of the Great Attractor, connecting its two main components -. Clusters of galaxies in the constellation Norma and South Triangle

About a third of the found scientists galaxies was unknown to astronomers, that means that the mass of the “Great Attractor” underestimated in the hundreds of trillions of solar masses. This, the authors say, may explain why the nature and power of attraction of this mysterious object found no rational explanation to date.
