Chemically primitive galaxy from 13 billion years ago reveals record-low oxygen

Article excerpt

An international team of astronomers has used the James Webb Space Telescope (JWST) and a natural phenomenon known as gravitational lensing to achieve a definitive characterization of LAP1-B, an ultra-faint galaxy from 13 billion years ago. Expanding upon initial detections, this new study revealed a record-breaking low oxygen abundance, merely 1/240th that of the sun.
