NASA's James Webb Space Telescope is on a mission to find the first galaxies and stars. Scott Pelley gets an inside look at what the telescope has discovered about the universe.
But astrophysicist Brant Robertson, who helped make the discovery as part of the JADES team, said that he doesn't expect the current record will hold for long. The telescope is so powerful that it's expected to find even earlier galaxies, he told 60 Minutes correspondent Scott Pelley.
Robertson, of the University of California, Santa Cruz, helps lead Webb's most ambitious mission, JADES, the JWST Advanced Deep Extragalactic Survey. That survey led to the discovery of a galaxy more than 33 billion light years away. It formed 320 million years after the Big Bang. "Either this is wrong or this is a huge discovery, and we think that it's a huge discovery," Nelson said.
