Scientists Discover Oxygen in The Most Distant Galaxy Ever
Scientists have detected oxygen in galaxy GHZ2, located 13.4 billion light-years away, offering new insights into the early universe, Daily Galaxy reported.
Using the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Webb Space Telescope (JWST), researchers observed faint emissions revealing the galaxy’s elemental composition and intense star formation activity just a few hundred million years after the Big Bang.
GHZ2 is a compact, dense galaxy with low metallicity—about one-tenth that of the Sun—indicating a young cosmic environment.
This discovery sheds light on galaxy evolution and the origins of dense star clusters. Astronomers emphasize that further observations will deepen understanding of metal enrichment, star formation, and black hole growth in the early universe, marking a significant advance in astrophysics.
