Based on mass and increasingly precise radius limits, astronomers have concluded that Sagittarius A* must be the central supermassive black hole of the Milky Way galaxy. [11] The current best estimate of its mass is 4.297 ± 0.012 million solar masses .
29 Αυγ 2013 · The center of the Milky Way galaxy, with the supermassive black hole Sagittarius A* (Sgr A*), located in the middle, is revealed in these images. As described in our press release, astronomers have used NASA’s Chandra X-ray Observatory to take a major step in understanding why material around Sgr A* is extraordinarily faint in X-rays.
12 Μαΐ 2022 · Sagittarius A*, often abbreviated to Sgr A* and pronounced "Sagittarius A star", is a supermassive black hole located at the center of our spiral galaxy, the Milky Way.
Sagittarius A (Sgr A) is a complex radio source at the center of the Milky Way, which contains a supermassive black hole. It is located between Scorpius and Sagittarius, and is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way.
