Observations from the James Webb Space Telescope have detected evidence of heavy elements in galaxies at redshift 9, roughly 500 million years after the Big Bang. The findings indicate that early galaxies had already formed and dispersed multiple types of metals by the beginning of cosmic reionization.
The research, published in *Nature*, describes this movement of metal-enriched matter as baryon cycling occurring before the midpoint of reionization. Quantum Zeitgeist reported that six different types of metals were detected in the galaxies.
