Webb spots clues of a black hole at the heart of nearby galaxy M83 Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered evidence that suggests the presence of a long-sought supermassive black hole at the heart of the nearby spiral galaxy Messier 83 (M83). This surprising finding, made possible by Webb's Mid-Infrared Instrument (MIRI), reveals highly ionized neon gas that could be a telltale signature of an active galactic nucleus (AGN), a growing black hole at the center of a galaxy.
