Milky Way and supermassive black hole
The Milky Way galaxy is believed to contain a single supermassive black hole at its center, besides a few hundred thousand stellar black holes; known as Sagittarius A* (pronounced "Sagittarius A-star"). This black hole has a mass estimated to be about 4.1 million times that of our Sun. While there may be numerous smaller black holes scattered throughout the Milky Way, astronomical evidence points to Sagittarius A* as the prominent supermassive black hole in our galaxy. Researchers continue to study the galaxy to uncover more about black holes, but as of now, the consensus is that the Milky Way hosts one supermassive black hole.
