Overview

• NASA's Hubble Space Telescope and Chandra X-ray Observatory detected the closest pair of supermassive black holes ever found.
• The black holes are located in the gas-rich galaxy MCG-03-34-64, approximately 800 million light-years away.
• These black holes are currently 300 light-years apart and are expected to merge in about 100 million years.
• The discovery was made through multiwavelength observations, revealing bright active galactic nuclei fueled by infalling gas and dust.
• The eventual collision will produce gravitational waves, providing valuable data for future astronomical research.
