Sagittarius A*
Sagittarius A* is the compact radio source identified as the Milky Way’s central supermassive black hole, located about 26,700 light-years from Earth. Its mass is roughly four million times that of the Sun, and in May 2022 it became the second black hole ever imaged directly by the Event Horizon Telescope. In 2024, horizon-scale polarimetric imaging revealed strong, organized magnetic fields near its event horizon.
