Supermassive black hole spews energy 300,000 light years into deep space

AI-summarised brief · reviewed before publication

A study by Satoshi Yamada and colleagues used Japan’s XRISM X‑ray satellite to observe the quasar H1821+643, located 3.4 billion light‑years away. Their data show that winds from the quasar’s supermassive black hole are roughly 100 times more powerful than previously thought, injecting energy equivalent to billions of supernovae. The outflows create turbulence that extends about 300,000 light‑years beyond the host galaxy, far into the surrounding galaxy cluster. The findings, published in Nature Astronomy, revise estimates of black‑hole feedback on large scales.

💡 Why It Matters

  • · The study demonstrates that black holes can redistribute vast amounts of energy across intergalactic space, reshaping our understanding of galaxy‑cluster evolution.
