The swirling mass around a black hole is called an "event horizon," the point of no return beyond which not even light can escape. Scientists unveiled the first image of this on Wednesday.
Every image you've ever seen of a black hole has been a simulation. Until now. "We have seen what we thought was unseeable," said Event Horizon Telescope Director Shep Doeleman.
