Astronomers have made a groundbreaking discovery of massive galaxies dating back to within 600 million years of the Big Bang, using the new James Webb Space Telescope. These galaxies appear to be mature, with a large fraction of their stars in place, suggesting that the early universe may have had a stellar fast-track. This discovery provides evidence that galaxies can form and mature quickly, opening up a new realm of possibilities for further research into the formation of the universe.
