At about 600 million years after the Big Bang, they're not the oldest galaxies the telescope has spotted. But they appear as developed as our Milky Way far further along than researchers expected.
The James Webb Space Telescope has seen even older galaxies, dating to within 300 million years of the beginning of the universe. But it is the size and maturity of these six galaxies that excite scientists.
CAPE CANAVERAL, Fla. (AP) Astronomers have discovered what appear to be massive galaxies dating back to within 600 million years of the Big Bang, suggesting the early universe may have had a stellar fast-track that produced these “monsters."
