The James Webb Space Telescope (JWST) just spotted round clusters of stars inside a galaxy more than 13 billion light years away, which formed just a few hundred million years after the Big Bang. The new discovery may shed light on how the universe’s earliest galaxies formed and evolved, and how they helped light up the universe after the Cosmic Dark Ages. And it turns out that close-knit balls of stars called globular clusters may have played an important role.
