New observations from the James Webb Space Telescope are reshaping astronomers' understanding of the universe's first billion years. Rather than a pristine cosmos made only of hydrogen and helium, Webb is finding early galaxies already seeded with heavier elements, suggesting the first generations of stars formed and died faster than expected.
