Astronomers using the James Webb Space Telescope discovered over a dozen dormant galaxies in the early universe, challenging previous expectations that young galaxies should be actively forming stars. These galaxies, which paused star formation between 10 and 25 million years ago, suggest a cyclical pattern of starburst and quiescence, possibly driven by stellar feedback processes. The findings, still preliminary, open new avenues for understanding galaxy evolution and the mechanisms that regulate star formation in the early cosmos.
