The observatory locations ranged from Spain to the South Pole and from Chile to Hawaii. “I mean, what’s more cool than seeing the black hole at the centre of the Milky Way?” Black-hole observationsĭuring five nights in April 2017, the EHT collaboration used eight observatories across the world to collect data from both the Milky Way’s black hole - called Sagittarius A*, after the constellation in which it is found - and M87*, the one at the centre of the galaxy M87.īlack hole pictured for first time - in spectacular detail

“We’ve been working on this for so long, every once in a while you have to pinch yourself and remember that this is the black hole at the centre of our Universe,” said EHT team member Katie Bouman, a computational-imaging researcher at the California Institute of Technology in Pasadena, at a press conference in Washington DC. The team published its results in a special issue of The Astrophysical Journal Letters 1. “Today, right this moment, we have direct evidence that this object is a black hole,” said Sara Issaoun, an astrophysicist at the Harvard and Smithsonian Center for Astrophysics in Cambridge, Massachusetts, at a press conference in Garching, Germany. The long-awaited results, presented today by the Event Horizon Telescope (EHT) collaboration, show an image reminiscent of the earlier one: a ring of radiation surrounds a darker disk of precisely the size that was predicted from indirect observations and from Albert Einstein’s general theory of relativity. 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. Radioastronomers have imaged the supermassive black hole at the centre of the Milky Way.
