Astronomers have detected oxygen in the galaxy JADES-GS-z14-0, located 13.4 billion light-years away, utilizing the ALMA and James Webb telescopes. This galaxy contains ten times more heavy elements than anticipated, challenging previous theories about the formation of the early universe.
This discovery necessitates a complete reevaluation of galaxy evolution theories, implying that stars and elements formed earlier than previously believed. It suggests that galaxies in the early universe matured at a significantly faster rate than current models predict.
