An unexpectedly rich array of early galaxies that was largely hidden until now has been observed by researchers using data from NASA’s James Webb Space Telescope. The researchers found two exceptionally bright galaxies that existed approximately 350 and 450 million years after the big bang. Their extreme brightness is puzzling to astronomers and challenges existing models of galaxy formation.
Two super-bright galaxies from universe's earliest years point to stars possibly being formed 100 million years before previously thought, though more data needed to verify claim
NASA's Webb Space Telescope has captured luminous images of early galaxies that were previously unseen by astronomers. The findings need more verification, but they may have been formed, according to scientists, just 350 million years before the universe began.
