"Spiral Galaxies Abounded in the Early Cosmos, Studies Indicate"
A new study using data from the James Webb Space Telescope has revealed that spiral galaxies were much more common in the early universe than previously thought. Researchers found that about a fifth of galaxies at redshift z=3, which corresponds to less than two billion years after the Big Bang, were spiral galaxies. This challenges the notion that spiral galaxies mainly form from mergers and collisions over time, suggesting that other factors contribute to their formation. The findings, which are based on observations from the Cosmic Evolution Early Release Science Survey (CEERS), indicate that many galaxies evolved into spirals much earlier than expected, and further research is needed to understand the underlying processes.
