Some 800 million years after the Big Bang, the universe shed a primordial fog of neutral hydrogen and became the transparent cosmos we know — a transformation called reionization whose cause has long eluded astronomers. Now, the James Webb Space Telescope has identified 83 tiny, fiercely burning starburst galaxies from that pivotal era, suggesting that the humblest of cosmic actors may have lit the way for all the light that followed. Their smallness, it turns out, was not a limitation but a gift: low-mass galaxies let ultraviolet radiation escape more freely, and in sufficient numbers they ma
