Quasars' powerful winds halted star formation in early galaxies

Super quasars are likely responsible for halting star formation in early galaxies. New research using the James Webb Space Telescope identified exceptionally fast winds from quasars one billion years after the Big Bang, suggesting they expelled gas needed for star creation. This discovery helps explain why many early galaxies stopped forming stars prematurely, a long-standing mystery in cosmology.
