Supermassive black hole winds are 100 times more powerful than scientists thought

Astronomers have discovered that winds from a supermassive black hole are about 100 times more powerful than previously thought. XRISM observations showed the resulting turbulence spreading roughly 300,000 light-years, extending far beyond the black hole’s host galaxy. The energy involved rivals several billion supernova explosions, revealing just how dramatically black holes can influence the space around them.

Supermassive black hole winds are 100 times more powerful than scientists thought. Although a black hole is more than 100 million times smaller than the radius of its host galaxy, it plays a crucial role in the galaxy’s central region. New observations suggest that winds driven by these enormous objects can carry energy across roughly 300,000 light-years, reaching far beyond the galaxies that host them.

Researchers found that the energy associated with these winds is about 100 times greater than earlier estimates, revealing that black holes can affect vast regions of space on a truly enormous scale. "Black holes are largely known for sucking matter in, but they also eject gas in the form of powerful winds," says Satoshi Yamada, Assistant Professor at Tohoku University’s Frontier Institute for Interdisciplinary Sciences (FRIS). "These winds were thought to be contained within the galaxy, but our study revealed that the force is immensely more powerful than previously understood."
