Oxygen Defies Time at the Dawn of the Universe Peering back nearly to the beginning with the James Webb Space Telescope, astronomers have uncovered a shocking surprise in the ultra-distant galaxy JADES-GS-z14-0: abundant oxygen — forged in the hearts of massive stars — already thriving when the cosmos was just 300 million years old.The infant universe was almost pure hydrogen and helium, with heavier elements supposed to take billions of years to appear. Yet here, in this record-breaking galaxy (redshift z ≈ 14.18), oxygen shines brightly, demanding multiple generations of furious star birth, explosive deaths, and rapid chemical pollution — all happening at breakneck speed, far faster than any standard model predicted. The abundance is staggering: roughly 10 times more heavy elements (metals) than theory allowed for such an ancient epoch. This galaxy isn't just chemically mature — it's also unexpectedly large, luminous, and dynamic, suggesting the early universe was a wildly energetic place where galaxies ballooned, evolved, and enriched themselves in cosmic hyperdrive.If JADES-GS-z14-0 is a sign of things to come (and not a freak outlier), we may need to rewrite the entire timeline of how the first galaxies ignited, grew up, and seeded the ingredients for planets — and perhaps life — much earlier than we ever imagined. The young cosmos was no quiet nursery… it was a blazing forge.
