Oxygen detected in a galaxy 13.4 billion light-years away challenges models of early universe formation.
Astronomers have detected oxygen in the most distant galaxy discovered, JADES-GS-z14-0, located 13.4 billion light-years away.
This finding, made using the James Webb Space Telescope and ALMA, indicates the galaxy formed and matured much faster than expected, challenging previous models of early galaxy formation.
The presence of oxygen suggests the galaxy contains about 10 times more heavy elements than anticipated, requiring scientists to reassess their understanding of the early universe.
