Astronomers have discovered Alaknanda, a surprisingly mature spiral galaxy that formed only 1.5 billion years after the Big Bang. Revealed by the James Webb Space Telescope and magnified by the Abell 2744 cluster, it shows a fully developed Milky-Way-like structure with clear spiral arms, a bright central bulge, and a large rotating disk. Despite its early age, Alaknanda spans 30,000 light-years, holds 10 billion solar masses of stars, and is rapidly forming new stars—about 60 Suns per year. Its unexpectedly advanced structure challenges current models of galaxy evolution, suggesting the early Universe matured far faster than scientists believed.
