Four ancient galaxies discovered by the James Webb Space Telescope in the first few months of operation have been confirmed by astronomers to be the oldest galaxies ever discovered by mankind and to be almost as old as the cosmos itself.
The light from the four galaxies took more than 13.4 billion years to reach Webb, according to scientists. More specifically, the telescope observes the galaxies as they appeared only 350 million years after the Big Bang, or 2% of the universe’s present age, even though the galaxies must have begun to form even earlier.
