At the center of our Milky Way galaxy lies a supermassive black hole known as Sagittarius A* (Sgr A*). Located about 26,000 light-years from Earth in the galactic center, this black hole has a mass of roughly 4 million times the Sun. Sagittarius A* anchors the Milky Way’s core, influencing the motion of stars, gas, and dust through its immense gravitational pull, making it a key object in astrophysics, galactic dynamics, and cosmology. The center of the black hole itself is called the singularity, a region where gravity becomes infinite, spacetime curves extremely, and the known laws of physics break down. Surrounding it is the event horizon, the boundary beyond which nothing—not even light—can escape. Material falling inward forms an accretion disk, heating up and emitting radio waves, X-rays, and infrared radiation, which astronomers use to study black hole behavior. Sagittarius A* plays a vital role in shaping the structure and evolution of the Milky Way galaxy.
