Supermassive black holes are best known for their immense gravity, pulling in everything that strays too close, even light. But new research suggests these cosmic giants can also hurl enormous amounts of energy outward, driving powerful disturbances that ripple hundreds of thousands of light-years through space.
A study led by Satoshi Yamada of Tohoku University in Japan found that winds generated by an actively feeding supermassive black hole are about 100 times more powerful than astronomers previously estimated.
These outflows, scientists say, inject an amount of energy comparable to several billion supernova explosions, driving turbulence through hot gas across distances of roughly 300,000 light-years —far beyond the boundaries of the host galaxy itself.
