The First Observed Black Hole

Scientists with the National Science Foundation (NSF) and the Event Horizon Telescope (EHT) announced on April 10, 2019 that they have obtained the first visual record of a supermassive black hole and its shadow. Utilizing an international network of eight ground-based radio telescopes, a collaborative team of more than 200 researchers captured images of the black hole at the center of Messier 87, a massive galaxy in the Virgo galaxy cluster. The black hole is some 55 million light years from Earth and has a mass 6.5 billion times that of the Sun. The results of the years-long effort were published in a series of six papers in The Astrophysical Journal Letters, and were announced in a joint NSF/EHT press conference.
