Astronomers said Thursday that if the results were verified, this newly discovered throng of stars would beat the most distant galaxy identified by the Hubble space telescope – a record-holder that formed 400m years after the universe began. Launched last December as a successor to Hubble, the Webb telescope is indicating stars may have formed sooner than previously thought – perhaps within a couple million years of the big bang.Photograph: ESA, Nasa, CSA, STScI/AFP/Getty Imagesby an international team led by Rohan Naidu of the Harvard-Smithsonian Center for Astrophysics. The article elaborates on two exceptionally bright galaxies, the first thought to have formed 350m years after the big bang and the other 450m years after.

Naidu said more observations would be needed in the infrared by Webb before claiming a new record-holder. Although some researchers report having uncovered galaxies even closer to the creation of the universe 13.8bn years ago, those candidates have yet to be verified, scientists said at a
