Immediately in several press centers in the world, presentations were made of the results of the project of the Event Horizon Telescope - a virtual radio telescope the size of Earth. For the first time in history, scientists have shown the first real images of the so-called black hole shadow in the center of the super-giant galaxy Messier 87 (M87). One of these presentations was held at the National Press Center in Washington, DC, where Shep Doleman, the head of the Event Horizon Telescope project, showed images of the object.
Most modern astronomers believe that in the center of all galaxies are supermassive black holes - objects with a mass of millions and billions of solar, continuously attracting and absorbing any matter, part of which is “chewed” by a black hole and ejected in the form of relativistic jets (jets) - thin plasma beams accelerated to near-light speeds.
In our galaxy, as well as in a number of others, this central black hole is in an inactive state — it does not emit jets. Scientists have long been trying to figure out when she “fell asleep” and how active she was in the past. In addition, astrophysicists would like to know how this activity affected the life of stars in the center of our galaxy and its surroundings.
They are trying to solve the riddle with the help of a giant virtual interferometer Event Horizon Telescope - a network of highly sensitive radio observatories interconnected in different locations of our planet, including the South Pole of the Earth. His training began more than 10 years ago.
