Black hole physics, galaxies, M87, general relativity, interferometric technique.

A black hole is an object with an extreme gravitational tugfrom which no light can escape. The nature of their stronggravity causes any material coming within the influence of itsevent horizon to be lost forever. The radiation from the hotdisk of matter encircling the black hole opens the possibilityto image these elusive objects, as it is impossible otherwise.Here, the first-ever image of the shadow of the supermassiveblack hole in a nearby galaxy, M87, is reported based on theobservations by the Event Horizon Telescope.
