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

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 pr
