The presence of oxygen is discovered in the most distant galaxy known
Two international teams have independently discovered the presence of oxygen in the galaxy JADES-GS-z14-0, the most distant known. The finding, which has been made using the ALMA telescope at the European Southern Observatory (ESO), could mean that galaxies evolved much earlier than previously thought. The results are published in the journals Astronomy & Astrophysics and The Astrophysical Journal.
