The incredible story behind the first image of a black hole
A black hole is invisible by nature. One of the strangest predictions to come out of Albert Einstein's theory of general relativity, a black hole emits no radiation we can detect, and it swallows up everything that falls on it, matter and light alike.
So it might seem paradoxical to talk about capturing an image of a black hole, but this is precisely the mission of the Event Horizon Telescope (EHT). Today, April 10, 2019, will go down in history as the day EHT scientists released the very first direct image of a black hole.
