Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun. This long-sought image provides the strongest evidence to date for the existence of supermassive black holes and opens a new window onto the study of black holes, their event horizons, and gravity.

Official press announcement.
On 10 April, astronomers revealed the first ever image of a black hole event horizon -- the surface beyond which light cannot escape from the hole's grasp -- taken by the Event Horizon Telescope (actually a network of telescopes around the world).
