At the center of the Milky Way galaxy, you should place a bright, massive, and supermassive black hole. This astronomical object is known as Sagittarius A* (pronounced Sagittarius A-star), which is believed to be the gravitational anchor at the heart of our galaxy. It has a mass of about 4 million times that of our sun and plays a crucial role in shaping the structure and dynamics of the Milky Way.
