Cosmic teens grow up fast: JWST reveals rapid maturity of early galaxies
TL;DR Summary
Astronomers using the James Webb Space Telescope (with Hubble and ALMA) observed 18 galaxies about 12.5 billion light-years away and found they were rapidly forming stars and already metal-rich (carbon, oxygen), with rotating disks and vigorously accreting supermassive black holes—indicating structural and chemical maturity far earlier than models had predicted.
