This is the first picture of a black hole.
Using the Event Horizon Telescope, scientists obtained an image of the black hole at the center of the galaxy M87. (There is a supermassive black hole at the center of our galaxy — the Milky Way.)
The black hole is outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon.
What is a Black Hole?
A black hole is a dense, compact object whose gravitational pull is so strong that – within a certain distance of it – nothing can escape, not even light.
Black holes are thought to result from the collapse of very massive stars at the ends of their evolution. The gravity is so strong because matter (the mass) has been squeezed into a tiny space.
