A A stronomers have found a pair of surprisingly gigantic galaxies from the early universe, and one is the most massive galaxy ever seen from when the universe was young. Observations show the pair of big galaxies existed less than 800 million years after the Big Bang, and their size doesn’t conform to current cosmological models, which say early galaxies were much smaller than today’s galaxies.
