Scientists have detected a mysterious gamma-ray heartbeat from a cosmic gas cloud in the constellation Aquila, powered by a neighbouring precessing black hole. The research team analysed over ten years of data from NASA's Fermi gamma-ray space telescope, revealing a consistent period between the cloud's emission and the black hole's jets.
