Astronomers detect Milky Way’s second-largest known black hole
A black hole with a mass 33 times greater than the sun was discovered in the Milky Way, located 2,000 light-years from Earth in the constellation Aquila. The black hole, named Gaia BH3, formed from a star with low metallicity and is the largest-known stellar black hole. Its companion star orbits it on an elliptical path, and the discovery supports the theory that massive stellar black holes can only be produced by low metallicity stars. The maximum size of stellar black holes is still a topic of scientific debate.
