"The Discovery: Astronomers using James Webb Space Telescope have identified Zhúlóng, a massive spiral galaxy 5.2 billion light-years away, formed just 1.13 billion years after the Big Bang. The galaxy matches our Milky Way's mass and shows fully developed spiral arms. Why It Matters: This discovery challenges existing theories about galaxy formation, showing that complex spiral structures can form in just one billion years rather than the previously assumed billions of years, revolutionizing our understanding of early universe development."
