Two galaxies spotted in deep fields taken by the Webb telescope were extraordinarily ancient. Highlighted in the image above, galaxies 1 and 2 sit at redshifts of 10.5 and 12.5, dating them to just a few hundred million years after the Big Bang (it’s now been nearly 14 billion years since the beginning of the universe.)
