The event horizon is a boundary that marks the outer edge of black holes. It is the point at which nothing, not even light, can escape.

The Event Horizon Telescope had an enormous challenge to overcome in order to get an image of any black hole at all, owing to the tininess of its angular size.

The Event Horizon Telescope (EHT) is a network of synchronized observatories around the world and is famed for capturing the first image of a black hole.

Within that photon orbit is the event horizon, the region beyond which no light can escape. The size and shape of this black hole, the researchers say, is exactly as predicted in Einstein’s ...

The Event Horizon Telescope project. To see a black hole for the first time, the Event Horizon Telescope team used an array of radio telescopes in Hawaii, North, ...

The Event Horizon Telescope, however, tests general relativity much nearer to the black hole’s edge, which could highlight subtle effects of physics beyond general relativity.

But the event horizon itself isn't transparent, and you shouldn't be able to see the matter behind it. The black hole, as illustrated in the movie Interstellar, ...

Scientists with the Event Horizon Telescope (EHT) announced Wednesday that they’ve successfully imaged the event horizon of a supermassive black hole at the heart of the Messier 87 galaxy.

"The event horizon protects us from the unknown physics near a singularity," Loeb said. Related: Images: Black Holes of the Universe The size of an event horizon depends on the black hole's mass.
