It was discovered thanks to the James Webb-Firewire Telescope

Last week we saw a small sample of what James Webb Telescope Into space, he displayed what may be the deepest and most detailed infrared images of the universe to date. However, their contributions go further and within a few months, many scientists have come to conclusions about some aspect of the universe.

A group of researchers published an article in Archives, The Scientific Journal of Cornell University in the United States, where they noted that thanks to the James Webb Telescope it was possible to discover glass-z13a galaxy dating back 300 to 400 million years after the Big Bang.

“We’ve found two very compelling candidates for very distant galaxies,” says Rohan Naidoo, one of the researchers. new world. “If these galaxies are as far apart as we think, then the age of the universe is only a few hundred million years at that point.”

Oldest galaxy

This research has not been verified by space organizations for absolute proof, but their researchers are very optimistic about their discovery.

“They are very compelling candidates,” adds Naidoo. “We were sure JWST would see distant galaxies. But we’re a little surprised at how easy it is to spot them.”

Renowned science writer James O’Donoghue took to Twitter to explain more about this distant discovery:

🚨 JWST likely broke records, discovering a galaxy that existed when the universe was only 300 million years old! The light from GLASS-z13 took 13.4 billion years to hit us, but the distance between us is now 33 billion light-years due to the expansion of the universe! pic.twitter.com/5AcOBwHuO1

Before Webb, the most distant 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 was around when the universe was about 400 million years old. HD1 was discovered in April, and has been the record holder for only a few months. They now indicate that GLASS-z13 existed at a time of about 30 million years before HD1. Specialized media.

If that’s the size of James Webb’s discovery within just weeks of operation, scientists automatically increase their expectations with potential discoveries in the coming months.
