Abstract
A black hole is an object with an extreme gravitational tug from which no light can escape. The nature of their strong gravity causes any material coming within the influence of its event horizon to be lost forever. The radiation from the hot disk of matter encircling the black hole opens the possibility to image these elusive objects, as it is impossible otherwise. Here, the first-ever image of the shadow of the supermassive black hole in a nearby galaxy, M87, is reported based on the observations by the Event Horizon Telescope.
