At the heart of a galaxy 145 million light-years away, humanity's most powerful space telescope has witnessed something ancient and self-perpetuating: a supermassive black hole sustaining its own existence through a cycle of destruction and renewal. The James Webb Space Telescope has resolved, in extraordinary detail, how the very jets that a black hole unleashes to heat surrounding gas eventually produce the cooled filaments that fall back inward to feed it again. This discovery, centered on NGC 4696 in the Centaurus Cluster, transforms a decades-old paradox — how black holes avoid starving t
