Galaxy starves its supermassive black hole, loses 95% of its brightness

AI-summarised brief · reviewed before publication

Astronomers observed a distant galaxy's supermassive black hole being starved of matter, resulting in a 95% decrease in brightness over 20 years. The galaxy dimmed to 5% of its original brightness, demonstrating that black hole activity can change rapidly, contrary to current models. This discovery may prompt a revision of black hole feeding models, providing new insights into these cosmic phenomena and their impact on galaxy evolution.
