Event-Horizon Telescope (EHT)

The Event Horizon Telescope (EHT) is a project to create a large telescope array consisting of a global network of radio telescopes and combining data from several very-long-baseline interferometry (VLBI) stations around the Earth.

It is composed of many radio observatories or radio telescope facilities around the world to produce a high-sensitivity, high-angular-resolution telescope.

The aim is to observe the immediate environment of the supermassive black hole Sagittarius A* at the center of the Milky Way, as well as the even larger black hole in the center of the supergiant elliptical galaxy Messier 87, with angular resolution comparable to the black hole’s event horizon.

On April 10, 2019, the first image of the black hole inside galaxy Messier 87 was published.
