Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.
The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope [8] Astronomers now have evidence that there is a supermassive black hole at the center of the galaxy. [9] Sagittarius A* (abbreviated Sgr A*) is agreed to be the most plausible candidate for the location of this supermassive black hole.

In 1999 a violent outburst at V4641 Sgr was thought to have revealed the location of the closest known black hole to Earth, [22] but later investigation increased its estimated distance by a factor of 15. [23] The complex radio source Sagittarius A is also in Sagittarius, near its western boundary with Ophiuchus.
