RESEARCH BRIEFINGS 13 May 2026 Observations from the James Webb Space Telescope reveal that extremely fast, galaxy-scale outflows from luminous objects called quasars were much more frequent, and on average more powerful, about one billion years after the Big Bang than at later cosmic epochs. These outflows could easily escape their host galaxies and regulate the evolution of early massive galaxies. This is a summary of: Liu, W. et al. Extreme galaxy-scale outflows are frequent among luminous early quasars. Nature 653 , 368–372 (2026) .
