Supermassive black hole blows galactic gas at 2,235,600 mph; cuts off star power

Astronomers using the James Webb Space Telescope have confirmed that supermassive black holes can prevent star formation in galaxies. They observed a massive galaxy nicknamed "Pablo's Galaxy" from about 2 billion years after the Big Bang. The galaxy's black hole is expelling gas at 2,235,600 mph, starving the galaxy of fuel for new stars. This provides the first direct evidence of black holes halting star formation, a process that appears to occur rapidly without disrupting the galaxy's structure. Further observations will examine any remaining fuel and assess the black hole's broader influence.
