The team behind the Event Horizon Telescope Collaboration has revealed the first image of the supermassive black hole at the center of the Milky Way. The image shows the massive object at the center of our galaxy, known as Sagittarius A* (Sgr A* in astronomers’ shorthand), as a glowing ring of gas around a dark central region (the “shadow”). This view of light being bent by the gravity of a black hole some four million times more massive than our Sun offers the first visual evidence of the suspected nature of Sgr A*.
To mark this incredible achievement, we’re sharing Daily stories about black holes and other amazing moments from the history of astronomy, all based on scholarship freely available from JSTOR.
