Astronomers Detect Oxygen in Most Distant Known Galaxy, Redefining Early Universe Evolution

Astronomers detect oxygen in most distant galaxy ever found

Astronomers have made a surprising discovery about oxygen and elements in the most distant known galaxy.

Scientists Detect 'Unexpected' Oxygen in the Most Distant Galaxy Ever Found, Defying Ideas About the Early Universe

The findings suggest galaxies formed much more quickly than astronomers assumed

The most distant galaxy has oxygen, and that's no surprise

Before any stars formed in the Universe, there was no oxygen. This plot shows the abundance of the light elements over time, as the Universe expands and cools during the various phases of Big Bang Nucleosynthesis. By the time the first stars form, the initial ratios of hydrogen, deuterium, helium-3, helium-4, and lithium-7 are all fixed by these early nuclear processes. Credit: M. Pospelov & J.

Two different astronomy teams’ data show the oldest known galaxy in universe has oxygen

This image shows the precise location in the night sky of the galaxy JADES-GS-z14-0. Credit: ALMA (ESO/NAOJ/NRAO)/S. Carniani et al./S. Schouws et al/JWST: NASA, ESA, CSA, STScI, Brant Robertson (UC Santa Cruz), Ben Johnson (CfA), Sandro Tacchella (Cambridge), Phill Cargile (CfA). JADES-GS-z14-0 is the most distant confirmed galaxy ever found. New observations from 2 different teams of astronomers shows that the galaxy has oxygen, making scienti…

Astronomers have made a surprising discovery. They have found oxygen and heavy metals in the most distant galaxy ever discovered. The galaxy is 13.4 billion light-years from Earth, meaning it formed in the early days of the universe.

Oxygen detected in galaxy just 300 million years after big bang

Astronomers have detected oxygen in the most distant known galaxy, JADES-GS-z14-0, just 300 million years after the Big Bang. The discovery, made using the ALMA telescope, suggests galaxies formed and matured far more rapidly than previously believed. JADES-GS-z14-0, discovered in 2024, is the farthest confirmed galaxy observed, with its light traveling 13.4 billion years to reach Earth. Scientists expected the early universe to lack heavy eleme…
