The image shows the boundary between light and dark around a black hole, called the event horizon — the point of no return, where the gravity of the black hole becomes so extreme that nothing that enters can ever escape. At the center of the black hole, time and space become so curved upon themselves that the laws of physics break down completely. (nsf.gov)The historic first image of a black hole was kept under wraps for months by the Event Horizon Telescope team, according to Shep Doeleman, a Harvard astronomer who led the effort. A black hole (another name for such a singularity) consumes clouds of gas and stars that wander too close; not even light can escape. Somewhere in that vast collection was the image of a black hole.
