The Event Horizon Telescope network has captured the second-ever direct image of a black hole — called Sagittarius A* — at the center of the Milky Way.

Radio astronomers have imaged the super massive black hole at the centre of the Milky Way. It is only the second-ever direct image of a black hole, after the same team unveiled a historic picture of a more distant black hole in 2019.

The long-awaited results, presented today by the Event Horizon Telescope (EHT) collaboration, show an image reminiscent of the earlier one, with a ring of radiation surrounding a darker disk of precisely the size that was predicted from indirect observations and from Albert Einstein’s theory of gravity.

“Today, right this moment, we have direct evidence that this object is a black hole,” said astrophysicist Sara Issaoun of the Harvard Smithsonian Center for Astrophysics at a press conference in Garching, Germany.

“We’ve been working on this for so long, every once and a while you have to pinch yourself and remember that this is the black hole at the centre of our Universe,” said computational-imaging researcher and former EHT team member Katie Bouman at a press conference in Washington, DC. “I mean, what’s more cool than seeing the black hole at the centre of the Milky Way?”
