Astronomers using the James Webb Space Telescope have detected a distant, metal-poor galaxy whose unusually massive, ultraviolet-bright stars match the expected signatures of Population III — the universe’s first stars. Through the help of gravitational lensing and Webb’s infrared sensitivity, researchers observed light from just 800 million years after the Big Bang, offering one of the strongest clues yet to how the earliest stars ignited and shaped the first galaxies.
