Event Horizon Telescope

The Event Horizon Telescope team has captured the first image of the black hole at the heart of our own Milky Way galaxy. This supermassive black hole known as Sagittarius A casts a “shadow,” a dark central region surrounded by a ring of glowing hot gas. It has the mass of 4.6 *million* of our suns! On a long enough timeline all that will be left in the universe is a scattering of dying black holes.
