A new study using the James Webb Space Telescope (JWST) has observed a surprisingly mature galaxy, JADES-GS+53.18343−27.79097, formed within the first 700 million years after the Big Bang. This galaxy is about 100 times smaller than the Milky Way but shows advanced characteristics for its early age, featuring a dense star cluster at its center and a less dense outer region. Notably, star formation is accelerating in the galaxy’s outskirts, indicating ongoing development.
