There are a lot of clichés that get thrown around when talking about big scientific discoveries. Words like “breakthrough” or “game changing” are often used. They grab people’s attention, but it’s fairly rare that they apply.
Today’s announcement of the first image ever taken of a black hole (more precisely, of its shadow) truly rises up to that standard. By definition, nothing not even light, can escape the gravitational grasp of a black hole. This, however, is only true if you get too close, and the boundary between what can and cannot get away is called the event horizon.
This dark portrait of the event horizon was obtained of the supermassive black hole in the center of the galaxy Messier 87 (M87 for short) by the Event Horizon Telescope (EHT), an international collaboration whose support includes the National Science Foundation. This achievement is certainly a breakthrough, and we at NASA’s Chandra X-ray Observatory congratulate and applaud the hundreds of scientists, engineers, and others who worked on the Event Horizon Telescope to obtain this extraordinary result.
