which was used to create the first image of a black hole

Answer 1

The Event Horizon Telescope (EHT) project was used to create the first image of a black hole. It is a collaborative project involving multiple telescopes from around the world, working together as a virtual Earth-sized telescope. The first image was of the supermassive black hole at the center of the galaxy Messier 87 (M87), and it was captured using data collected by the EHT in April 2017. The historic image was released to the public on April 10, 2019.
