Sagittarius A*

Sagittarius A* is the supermassive black hole located at the center of the Milky Way Galaxy. It is the closest known supermassive black hole to Earth and serves as the gravitational anchor of our galaxy.

Key Points

It has an estimated mass of about 4.3 million times that of the Sun.
It lies approximately 26,000 light-years from Earth in the constellation Sagittarius.
Though generally dormant, it occasionally accretes gas and dust, producing emissions across the electromagnetic spectrum, especially strong radio waves.
Recent observations have provided evidence of outflowing winds from Sagittarius A*, helping scientists better understand how black holes interact with their surroundings.
