ALMA Finds Most-Distant Oxygen in the Universe

Astronomers detected a faint but definite signal of oxygen in a galaxy located 13.28 billion light-years away from us, through observations using the Atacama Large Millimeter/submillimeter Array (ALMA). Breaking their records, this marks the most distant oxygen ever detected in the Universe. Referencing infrared observations, the team determined that star formation in the galaxy started at an unexpectedly early stage: 250 million years after the Big Bang.
