Space telescope uncovers massive galaxies near cosmic dawn.
CAPE CANAVERAL, Fla. — 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.”
“While most galaxies in this era are still small and only gradually growing larger over time,” he said in an email, “there are a few monsters that fast-track to maturity. Why this is the case or how this would work is unknown.” These galaxy observations were among the first data set that came from the $10 billion Webb telescope, NASA and the European Space Agency’s Webb is considered the successor to the Hubble Space Telescope, coming up on the 33rd anniversary of its launch.
