For the first time, astronomers have captured an image of the supermassive black hole at the center of our galaxy.
It’s the first direct observation confirming the presence of the black hole, known as Sagittarius A*, as the beating heart of the Milky Way.
Black holes don’t emit light, but the image shows the shadow of the black hole surrounded by a bright ring of light, which is bent by the gravity of the black hole. Astronomers say the black hole is 4 million times more massive than our sun.
It has taken years for astronomers to capture and confirm this image and discovery. Previously, scientists observed stars orbiting some invisible, massive object at the galactic center.
The discovery was made possible by more than 300 researchers from 80 institutions working with a network of eight different radio telescopes around the globe that comprise the Event Horizon Telescope. The telescope is named after the “event horizon,” the point at which no light can escape from a black hole.
