BASIC INFO
Sagittarius A* (Sgr A*) is a supermassive black hole located at the center of the Milky Way galaxy. With a mass equivalent to about 4 million times that of the Sun, it exerts a strong gravitational influence on its surroundings. Despite being invisible to direct observation, Sgr A* is studied through its effects on nearby stars and gas clouds. Astronomers have observed stars orbiting around Sgr A* at high speeds, providing evidence for its existence. Surrounding Sgr A* is an accretion disk of gas and dust that emits radiation across the electromagnetic spectrum.

SOME RANDOM FACTS
Sagittarius A* emits radiation primarily in the millimeter-wave part of the electromagnetic spectrum.
Despite its massive size, Sagittarius A* is relatively quiet compared to other supermassive black holes.
It occasionally experiences flares of increased activity. These flares can last for several hours or days and are thought to be caused by interactions within the accretion disk.
