When was the first image of the Milky Way’s central black hole released?

The Event Horizon Telescope collaboration published the first image of Sagittarius A* on 12 May 2022. Sagittarius A* is the supermassive black hole at the center of our galaxy, about 27,000 light-years from Earth. The image revealed a glowing ring of hot gas around the black hole’s shadow. It provided another major confirmation of general relativity and showed that the Milky Way’s center contains a black hole about 4 million times the mass of the Sun.
