JWST Discovers Most Distant Giant Spiral Galaxy Yet

Using the James Webb Space Telescope (JWST), astronomers have discovered Zhúlóng, an ultra-massive spiral galaxy that is the most distant of its kind ever identified. This grand-design spiral, with its well-defined arms, boasts a mass comparable to the Milky Way and formed a mere billion years after the Big Bang. Studies reveal a quiescent core and a still-active star-forming disk, suggesting Zhúlóng is in a transitional phase. This discovery challenges existing models of early universe galaxy formation, indicating mature galaxies may have emerged much earlier than previously thought.
