WebThe black hole at the center of the Milky Way Galaxy is known as Sagittarius A* (Sgr A*), and it is estimated to have a mass of about 4 million times that of the Sun. Despite its massive size, Sgr A* is still relatively small compared to the size of the Milky Way Galaxy itself, which has a diameter of about 100,000 light-years. WebThe first direct image of a supermassive black hole, located at the galactic core of Messier 87. It shows radio-wave emission from a heated accretion ring orbiting the object at a mean separation of 350 AU, or ten times larger than the orbit of Neptune around the Sun. The dark center is the event horizon and its shadow. The image was released in 2024 by the …
