The James Webb Space Telescope has confirmed the existence of bright, large galaxies formed just 300 million years after the Big Bang, significantly earlier than previously thought. The study, published in Nature, indicates that these galaxies, including JADES-GS-ZZ14-0, are more numerous and luminous than earlier estimates, suggesting a rapid star formation period beginning 200 million years post-Big Bang.
