Astronomers have discovered the closest pair of supermassive black holes ever recorded, located just 300 light-years apart at the center of the galaxy MCG-03-34-64, which is 800 million light-years away. This remarkable finding, made using the Hubble Space Telescope and the Chandra X-ray Observatory, reveals that the black holes are on a collision course, destined to merge into a single, larger black hole. The duo is currently brightening as they consume surrounding gas and dust, functioning as active galactic nuclei (AGN). The discovery highlights the complex dynamics of galaxy mergers and the evolution of black holes, as these interactions are crucial to understanding cosmic structures. Lead researcher Anna Falcão noted that such a close pair is rare in the nearby universe and was found unexpectedly during routine observations. The study provides insights into future cosmic events, including potential scenarios for our own Milky Way and Andromeda galaxies.
