"Spiral Galaxies Abounded in the Youthful Cosmos"

A new study using data from the James Webb Space Telescope challenges the traditional view of galaxy formation by revealing a higher-than-expected number of spiral galaxies in the early Universe. The findings suggest that spiral galaxies formed much earlier than previously thought, with about a fifth of galaxies at redshift z = 3 (less than two billion years after the Big Bang) being spirals. This indicates that other factors besides galactic collisions and mergers may play a significant role in the formation of spiral galaxies. Further research with JWST data may uncover how these early galaxies evolved and the reasons behind the longstanding presence of spiral galaxies.
