Event Horizon Telescope

The Event Horizon Telescope (EHT) is a project to create a large array of telescopes, consisting of a global network of radio telescopes and combining data from several very long baseline interferometry (VLBI) stations around the Earth. The goal is to observe the immediate surroundings of the supermassive Sagittarius A* black hole at the center of the Milky Way, as well as an even larger black hole in the supergiant elliptical galaxy Messier 87, with an angular resolution comparable to the black hole's event horizon. On April 10, 2019, the first image of a black hole inside the galaxy Messier 87 was published. An algorithm for visualizing a supermassive black hole from data obtained by radio telescopes was developed by Katherine Bowman. In 2020, international cooperation on the project was awarded the Albert Einstein Medal. On May 12, 2022, the second image of the black hole was released. An image of the Sagittarius A* object located at the center of our Milky Way galaxy was obtained. It was formed from data collected by radio telescopes in 2017.
