Astronomers unveil portrait of Milky Way’s black hole

At the center of our galaxy lies a black hole that’s 4 million times more massive than our sun. On Thursday, scientists released the first picture of Sagittarius A*, which they estimate lies about 27,000 light-years from Earth.

How did we get the picture? The colorized image comes from eight synchronized radio telescopes scattered around the globe called the Event Horizon Telescope. Though a black hole does not emit light, the photo shows a glowing disk of matter that orbits a seemingly empty spot in the center, where Sagittarius A* sits. In 2019, the international consortium that manages the global network released the first-ever image of any black hole, located in a galaxy an estimated 53 million light-years away.
