Indian astronomers have identified Alaknanda, a fully developed spiral galaxy that existed just 1.5 billion years after the Big Bang, using public data from the James Webb Space Telescope (JWST).
Unlike typical early galaxies, Alaknanda already shows a rotating disk, two symmetrical spiral arms, and a central bulge — structures scientists believed usually take billions of years to form.
The galaxy was spotted as part of the UNCOVER survey, prompting fresh questions about how quickly galaxies formed and evolved in the early Universe.
