Thanks to the James Webb Telescope scientists would have discovered the oldest galaxy in the universe
Last week we got a glimpse of what the James Webb Telescope could be capable of in space, presenting what would be the most detailed and deepest infrared images of the universe yet. However, his contributions go further and in so few months, many scientists have drawn conclusions about some aspects of the cosmos.
A group of researchers published an article in Arxiv, the scientific journal of Cornell University in the United States, where they point out that thanks to the James Webb Telescope it was possible to discover GLASS-z13,a galaxy dating from 300 to 400 million years after the Big Bang.
“We found two very compelling candidates for extremely distant galaxies,” says Rohan Naidu, one of the researchers. New Scientist. “If these galaxies are as far apart as we think they are, the universe is only a few hundred million years old at that point.”

the oldest galaxy
This research has yet to be verified by space organizations for absolute proof, but its researchers are very optimistic about their finding.
“They are very compelling candidates,” adds Naidu. “We were pretty sure JWST would see distant galaxies. But we’re a little surprised at how easy it is to spot them.”
Well-known science writer James O’Donoghue took to Twitter to explain more about this distant discovery:
Before Webb, the farthest previously known galaxies in our universe were GN-z11 and HD1. As you can see from GN-z11’s name, its redshift factor, or “z,” was 11. Scientists said it existed when the universe was about 400 million years old. HD1 was discovered in April, however, and was the record holder for only a few months. Now it seems that GLASS-z13 existed at a time about 30 million years before HD1, specialized media point out.
If this is the magnitude of James Webb’s discovery in just weeks of operation, scientists automatically increase their expectations with possible discoveries in the coming months.
