Scientists have shown the first photo of the black hole Sagittarius A, located in the center of the Milky Way galaxy. It is 55 million and 26 thousand light years far from Earth and in order to “see” its details, it was necessary to unite the efforts of radio telescopes from all over the world.
April 10, 2019 astronomers hold a conference on the results of the so-called telescope “Event horizon”.
The black holes themselves are literally invisible – they absorb all electromagnetic radiation, which means that none of our telescopes: radio, X-ray, optical, gamma rays can detect them. But theoretically, it is possible to see the event horizon – a point outside the black hole, in which the light that extends from the observer outside, will never be able to go beyond the horizon.
The results of this experiment will show whether calculations of physicists that described such massive objects based on the theory of relativity were right. In other words, today’s theoretical physics depends largely on today’s news.
