Black Hole Seen in Closest Look Ever
Ground-based radio telescopes in Hawaii, Arizona, and California combined forces to examine the supermassive black hole at the center of the Milky Way.
Although by definition we can't see a black hole directly, we can see the bright region of radio emissions known as Sagittarius A* that's thought to be either a disk of matter swirling toward the black hole, or a high-speed jet of matter being ejected from it.
Astronomers noted that further study of Sagittarius A* should help us understand "what happens as matter is drawn near to the black hole and disappears forever."
