Record Breaking! Scientists Shocked by JWST’s Discovery of an Ancient Spiral Galaxy

JWST has discovered a fully formed spiral galaxy—Alaknanda—only 1.5 billion years after the Big Bang. Its structure is far too mature for its epoch, challenging everything we know about early galaxy formation. This surprising find pushes scientists to rethink how quickly galaxies could grow and settle in the early Universe.
