Webb Telescope Glimpses Universe's Earliest Galaxy Through Cosmic Magnifying Glass

Astronomers using the James Webb Space Telescope have observed the most chemically primitive galaxy discovered to date, formed just 800 million years after the Big Bang. By leveraging gravitational lensing from a massive galaxy cluster, researchers overcame the technical limitations that have long prevented observation of these ultra-faint ancient structures, opening a new window into how the universe's first stars ignited.
