Six galaxies found in 'deep field' images existing just 500-700 million years after the Big Bang are so massive that we need a new understanding of how the universe came to be, according to new research

On July 12, 2022 the universe changed forever. Scientist still don’t know for sure what happened, but on that Tuesday the first “deep field” images from the James Webb Space Telescope were released—and astronomy has been in a frenzy ever since. Over six months later the story of how our universe changed that day is becoming clearer, but the cause was clear—JWST’s ability to see back 13.5 billion years near the beginning of the universe as we know it.
“When we got the data [that day] everyone just started diving in and these massive things popped out really fast,” said Joel Leja, assistant professor of astronomy and astrophysics at Penn State and co-author of a paperabout the revolutionary data from JWST. He’s talking about six galaxies in JWST’s images existing 500-700 million years after the Big Bang—when the universe was only 3% of its current age—that appeared far more massive than anyone expected.
“It’s bananas,” said Erica Nelson, co-author of the new research and assistant professor of astrophysics at the University of Colorado Boulder. “You just don’t expect the early universe to be able to organize itself that quickly. These galaxies should not have had time to form.”
