Einstein helped found the lens galaxy of the dark matter

Astronomers have discovered a galaxy of dark matter. To find the invisible galaxies, scientists have used the so-called Einstein's lens - a method that allows to find objects by their gravitational effects on the environment. The work of the authors represented in the magazine. Nature. And its description is provided in a press release at the Massachusetts Institute of Technology (MIT).
The existence of dark matter was postulated in 1930 by Swedish astronomer Fritz Zwicky to explain the lack of mass in the universe - visible galaxies ' not enough ' to the celestial bodies behave as astronomers have observed. The title of this substance reflects its main feature: the dark matter is involved in the gravitational interaction and is not involved in the electromagnetic (that is, it can not be observed directly).
Quantitatively, the universe is much more dark matter than the ' normal '. Not long ago, astronomers have hypothesized that one of the types of objects, consisting of the invisible substance, are dwarf satellite galaxies of large star clusters. It is believed that the ' full ' galaxies like the Milky Way formed, attracting and absorbing their tiny neighbors. From this assumption it follows that such large star formation must be surrounded by a large number of small satellites ( in the case of the Milky Way is estimated to be the approximate number of 10,000 ). However, in reality, astronomers have found in the immediate vicinity of the galaxy, only about 30 ' neighbors '. Scientists have suggested that the rest of the galaxy for one reason or another were not able to form stars and are composed of dark matter.
The authors decided to find a new job this invisible companion system JVAS B1938 666, consisting of two galaxies that are on the same line with each other when seen from the Earth. This arrangement allows the use of the method of gravitational lensing, or Einstein's lens. Gravity of massive objects like galaxies appreciably declines path of light coming from more distant objects, and the parameters of this deviation depends on the mass of the deflecting ' lens '. Observing with Keck II telescope in Hawaii system JVAS B1938 666, astronomers found that the system rejects the path of light is not as predicted by theory. Accordingly, the researchers concluded that the existence of a system of satellites of dark matter.
This is the second galaxy, consisting of unobservable substance known to specialists. The first one was 18 times more massive than the present, and it was too big to be a companion galaxy,.

A priceless gift.

One day the father chastised her daughter for three years that she spent a gilt roll of wrapping paper. Money was tight and he was just mad because the child tried to decorate a little box for no apparent reason. Despite this, the next morning the little girl brought the gift to his father. She said:.

- This is for you, Daddy.

My father was astonished by this because the day before my daughter yelled at. But his indignation burst forth again, when he discovered that the box is empty. The father turned to his daughter:.

- Do not you know that when presented with a gift, it is assumed that the box will be based on something? .

The little girl looked up at him with tears in his eyes:.

- Daddy, it is not empty. I filled it with her kisses. They're all yours, Daddy!.

My father was struck. He knelt down and gently hugged her daughter and begged her for forgiveness. Since then, my father kept this precious gift beside his bed. If he has something kleilos in life, he remembered the kisses and the love that gave him a daughter. And it is much more important than all the troubles, material wealth, and quarrels over trifles.
