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.
