The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope [11] Astronomers now have evidence that there is a supermassive black hole at the center of the galaxy. [12] Sagittarius A* (abbreviated Sgr A*) is agreed to be the most plausible candidate for the location of this supermassive black hole.

At the time, it was considered to be the closest known black hole to Earth, at a distance of approximately 1,600 light-years (490 pc). Later observations showed it to be much farther away, reported in 2001 to be between 7.4 and 12.31 kpc , [ 7 ] 6.2 kpc in 2014, [ 4 ] and around 6.6 kpc according to its Gaia Data Release 2 parallax.
