The center of the Milky Way galaxy is dominated by a supermassive black hole called Sagittarius A* (pronounced Sagittarius A star), which has a mass approximately 4 million times that of the Sun
. This black hole is located about 26,000 light-years from Earth in the direction of the constellation Sagittarius
. Surrounding Sagittarius A* is a dense region known as the galactic bulge, containing around 10 million stars within one parsec, mostly older stars like red giants and supergiants formed in past star formation events
. The stars in this central area are packed extremely closely, with distances between stars much smaller than in the Sun’s neighborhood
. The galactic center is also a complex environment with evolved and young stars, molecular and ionized gas clouds, and phenomena such as giant magnetized outflows called Fermi bubbles, which extend above and below the center and are linked to intense star formation activity
. In summary, at the very heart of the Milky Way lies Sagittarius A*, a supermassive black hole surrounded by a dense cluster of stars and gas, making it a highly dynamic and crowded region of the galaxy
