JWST reportedly detected carbon and oxygen in galaxies 500 million years after the Big Bang
Another post says JWST/NIRSpec detected absorption by oxygen, silicon and carbon ions around three early galaxies.
TLDR
One post says JWST detected carbon and oxygen in galaxies just 500 million years after the Big Bang, earlier than expected. Another says JWST/NIRSpec detected absorption by oxygen, silicon and carbon ions around three early galaxies, interpreting it as evidence of gas flowing outward.
