Milky Way’s central black hole finally reveals its wind after decades of looking
After a 50-year search, astronomers using ALMA and NASA's Chandra X-ray Observatory have detected evidence of a wind flowing from Sagittarius A*, the Milky Way’s supermassive black hole. The wind appears to have carved a three-light-year cone in surrounding molecular gas, with X-ray data lining up to confirm the wind. Though relatively weak compared with winds from actively feeding black holes, it may have been active for about 20,000 years, providing a window into black hole outflows in a quiet state.
