What explains a grand-design spiral galaxy only 1.5 billion years after the Big Bang

The James Webb Space Telescope has discovered Alaknanda, a remarkably mature spiral galaxy existing just 1.5 billion years after the Big Bang. This well-organized structure, complete with a disc and arms, challenges existing theories about early cosmic evolution. Its existence suggests galactic formation may have been more efficient and rapid than previously believed, prompting a re-evaluation of cosmic timelines.
