Astronomers use Webb data to measure rapid increase in oxygen in the early universe

Using new data from the James Webb Space Telescope, astronomers have measured the abundance of oxygen in the early universe. The findings, accepted for publication in The Astrophysical Journal Supplement Series and posted to the arXiv preprint server, show that the amount of oxygen in galaxies increased rapidly within 500–700 million years after the birth of the universe, and has remained as abundant as observed in modern galaxies since then. This early appearance of oxygen indicates that the elements necessary for life were present earlier than expected.
