The Milky Way’s Most Massive Stellar Black Hole is Only 2,000 Light Years Away
The Milky Way’s Most Massive Stellar Black Hole is Only 2,000 Light Years Away Astronomers have found the largest stellar mass black hole in the Milky Way so far. At 33 solar masses, it dwarfs the previous record-holder, Cygnus X-1, which has only 21 solar masses. Most stellar mass black holes have about 10 solar masses, making the new one—Gaia BH3—a true giant. Supermassive black holes (SMBH) like Sagittarius A Star at the heart of the Milky Way capture most of our black hole attention. Those behemoths can have billions of solar masses and have enormous influence on their host galaxies. But stellar-mass holes areRead More →
