The NASA/ESA/CSA James Webb Space Telescope (JWST) has made a groundbreaking discovery by identifying young star clusters in the Cosmic Gems arc, a galaxy that existed 460 million years after the Big Bang. This finding, facilitated by gravitational lensing, offers new insights into early star formation and the reionization of the Universe. The discovery marks the first time star clusters have been observed in such an infant galaxy, less than 500 million years after the Big Bang, providing a deeper understanding of the Universe when it was about 3% of its current age.
