Astronomers have made significant discoveries about galaxy formation using the James Webb Space Telescope (JWST). One study reveals a galaxy growing from the outside in, where new star formation is concentrated in the outskirts while the core contains older stars, challenging previous models of galactic evolution. Another team identified a population of stars over 13 billion years old, termed PanGu, which may represent the original disk structure of the Milky Way, suggesting it formed earlier than previously thought. Additionally, the discovery of the earliest known rotating disk galaxy, REBELS-25, challenges existing theories of galactic growth by exhibiting orderly features at an unexpectedly early stage. These findings collectively enhance our understanding of how galaxies, including our own, evolve over cosmic time. The JWST's capabilities have opened new avenues for probing the early universe and the processes that shaped it.
