概要

Astronomers have observed a distant galaxy dimming to just 5% of its original brightness in only two decades. The cause: a sudden drop in gas feeding its central supermassive black hole.

This discovery shows that active galactic nuclei can evolve on human timescales, challenging existing models and reshaping our understanding of black hole behavior.
