Sagittarius A is a complex and intense radio source in the direction of the center of the Milky Way, and also a powerful infrared and X-ray radiation source. However, it cannot be directly observed by visible light because it is covered by a large amount of cosmic dust in the spiral arms of the Milky Way. Astronomers have long speculated that these rays may be related to the activity of black holes.

Sagittarius A consists of three parts: East Sagittarius A, West Sagittarius A and Sagittarius A*. German scientists confirmed in February 2008 that Sagittarius A*, which is 26,000 light years away from the Earth, is indeed a supermassive black hole (the mass is about 43 1000 times that of the sun).
