Using the Event Horizon Telescope, scientists obtained an image of the black hole at the center of the galaxy M87, and released it on April 10, 2019. The black hole is about 55 million light-years away, in the center in the Virgo cluster. The supermassive black hole has a mass approximately 6.5 billion times that of our Sun.
The Event Horizon Telescope, is a planet-scale array of eight ground-based radio telescopes forged through international collaboration which are not physically connected but are able to synchronize their recorded data with hydrogen masers, a type of atomic clocks which allows the to precisely times their observations. Led by the Center for Astrophysics | Harvard & Smithsonian, the collaboration includes over 300 members aiming to image black holes to test Einstein’s general relativity. The same team of scientists released the first image of the black hole at the center of our own galaxy, Sagittarius A* (Sgr A*), in 2022.
