James Webb spots super old, massive galaxies that shouldn\’t exist

Astronomers have discovered six potential galaxies that emerged so early in the universe\’s history and are so massive they should not be possible under current cosmological theory. The galaxies were spotted in images from the James Webb Space Telescope, and are estimated to have existed at the dawn of the universe, around 500 to 700 million years after the Big Bang. This discovery is pushing the limits of our understanding of cosmology, and is a culmination of a journey that began for one of the researchers when she was in elementary school. The team still needs more data to confirm that these galaxies are as big as they look and date as far back in time, but their preliminary observations offer a tantalizing taste of how James Webb could rewrite astronomy textbooks.
