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

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. ...
