Not so long ago we wrote about a team of American and Hungarian researchers, who suggested the absence of a dark universe matter – a hypothetical substance that does not emit electromagnetic radiation and not interacting directly with it, and therefore invisible to direct observation. Experts put forward the theory that in fact most of the universe consists of emptiness, and not from dark matter, as was previously thought.
Now, Canadian astronomers who claim that they managed to get the first image of the mysterious dark matter, thereby proving it once and for all Existence. University of Waterloo employees in a special way photographed dark matter, playing the role of a peculiar “bridge” that connects two galaxies. Results of this studies were published recently in an authoritative journal on Astronomy and Astrophysics Monthly Notices of Royal Astronomical Society. ”
Scientists estimate that dark matter is about 25 percent of the total mass of the universe. She, as mentioned above, is not interacts with electromagnetic radiation and completely transparent, so fix it with traditional methods impossible. However, this mysterious substance possesses gravity. Due to this, it affects the movement galaxies, as well as the distribution of matter in the universe, forming coarse-grained structure of the universe.

In addition, due to its gravitational properties, dark matter knows how to bend space, thereby changing the trajectory light rays. This leads to the so-called effect. gravitational lensing, which is distortion an object located behind a clot of this substance.
To get the picture of the dark mother presented here, Canadian researchers took advantage of technology weak gravitational lenses. This method allows you to get an image. invisible mass, which is located on the borders of galactic systems. It can be a black hole or dark matter, and in our case we are talking about the second option. Connecting galaxies, dark matter causes deformations – this allowed scientists to discover it.
The photo shows more than 46 thousand space galaxies, 5 billion light-years from our the planet. The picture also shows the strings of a dark mother, connecting different galaxies.
