NASA’s James Webb Space Telescope has revealed dozens of galaxies that could be among the earliest known in the universe. Using early observations from the telescope, astronomers looked for galaxies at very high redshifts, which would indicate that these galaxies formed earlier in the universe. The team detected 87 galaxies that may have been the first to appear in the universe, about 200 to 400 million years after the Big Bang. “Finding such a large number of galaxies in the early parts of the universe suggests that we might need to revise our previous understanding of galaxy formation,” said Haojing Yan, an astronomer at the University of Missouri. “Our finding gives us the first indication that a lot of galaxies could have been formed in the universe much earlier than previously thought.”
