"James Webb Space Telescope Challenges Cosmic Norms with Early Galaxies' Star Formation"

The James Webb Space Telescope (JWST) has discovered that early galaxies in the universe defied the "cosmic rulebook" of star formation. By observing galaxies as far back as a few hundred million years after the Big Bang, the JWST found that these ancient galaxies produced fewer heavy elements than expected based on later galaxies. The team suggests that the lower metallicity may be due to the continuous influx of new, pristine gas from the intergalactic medium, diluting the heavy elements inside the galaxies. This discovery challenges current models of galactic evolution and sheds light on the fundamental processes that shaped the universe.
