NASA's James Webb Space Telescope discovers earliest galaxy ever seen in the universe
Source: YouTube The James Webb Space Telescope (JWST) has once again made history by discovering the most distant and ancient galaxy ever observed, named MoM z14. Located just 280 million years after the Big Bang, this galaxy pushes the boundaries of cosmic observation. The finding highlights JWST's exceptional ability to peer into the early universe, offering unprecedented insights into the formation of the first galaxies. With its record-breaking redshift of z = 14.44, MoM z14 not only redefines our understanding of galaxy evolution but also suggests that even earlier galaxies may soon be within reach, marking a new era in astronomy. JWST discovers one of the earliest galaxies formed after the Big Bang NASA's $10 billion space telescope has spotted a galaxy that was present only 280 million years after the Big Bang, a time that astronomers refer to as "cosmic dawn." The discovery team dubbed this galaxy MoM z14—"Mother of all early galaxies" for short. "First and foremost, at the moment, this is the most distant object known to humanity," said Pieter van Dokkum, Yale University professor of Astronomy and Physics, in an interview. 'MoM z14 existed when the universe was about 280 million years old—we're getting quite close to the Big Bang. Just to put that in context, sharks have been around on Earth for a longer timespan!' Since entering service in mid-2022, the JWST has been outstanding at detecting very distant galaxies by means of an effect known as redshift. When the universe gets bigger, light from old galaxies gets stretched, moving toward the red end of the spectrum. The more distant and thus older the galaxy is, the higher the redshift. Prior to MoM z14, the then-record holder was a galaxy named JADES-GS-z14-0, seen at a redshift of z = 14.32, some 300 million years following the Big Bang. MoM z14 is all the more impressive with a redshift of z = 14.44, extending modern astronomy's observational limits. Discovery of MoM z14 reshapes the view of galaxy formation In van Dokkum's view, the discovery of MoM z14 is not merely a new record—it provokes earlier hypotheses on the early formation of galaxies. "The bigger picture here is that JWST wasn't supposed to discover any galaxies this early in the universe's history at least, or at least at this point in the mission," he states. Previous JWST models predicted significantly fewer bright galaxies in the universe's early days. Current observations indicate more than 100 such galaxies exist in the early universe—significantly more than before. What sets MoM z14 apart Aside from its record-setting age, scientists were able to glean useful insight into MoM z14's composition and structure: Size: Roughly 50 times smaller than the Milky Way. Star formation: The galaxy possesses unexplained emission lines showing that it is extremely young and quickly producing new stars. Chemical composition: Existence of carbon and nitrogen, which implies that it's not one of the absolute first generation galaxies. "These things suggest that there had to be previous galaxies made only of hydrogen and helium that existed prior to MoM z14," said van Dokkum. "MoM z14 might be the first generation of 'normal' galaxies that started making heavier elements using processes in stars."

Hi, 'Mom'! James Webb telescope discovers MoM-z14 — the most distant, early galaxy ever seen
When you buy through links on our articles, Future and its syndication partners may earn a commission. The James Webb Space Telescope (JWST) has spotted the most distant galaxy observed to date — breaking its own record yet again. The galaxy, dubbed MoM-z14, is "the most distant spectroscopically confirmed source to date, extending the observational frontier to a mere 280 million years after the Big Bang," researchers wrote in a new study that appeared May 23 on the preprint server arXiv. In other words, the galaxy emitted light just 280 million years after the birth of the universe; after its long journey across the cosmos, that light is only now reaching Earth and JWST's infrared sensors. "It's pretty exciting," Charlotte Mason, an astrophysicist at the University of Copenhagen who wasn't involved in the study, told New Scientist. "It confirms that there really are these very bright galaxies in the universe." Since beginning operation in 2022, JWST has spotted more bright, ancient galaxies than scientists expected, challenging previous theories about the universe's infancy. "This unexpected population has electrified the community and raised fundamental questions about galaxy formation in the first 500 [million years after the Big Bang]," the authors wrote. As more examples trickle in, scientists are working to confirm whether these luminous objects really are ancient galaxies. Study lead author Rohan Naidu, an astrophysicist at MIT, and colleagues combed through existing JWST images for potential early galaxies to check. After identifying MoM-z14 as a possible target, they turned the telescope toward the peculiar object in April 2025. One way scientists can measure an astronomical object's age is by measuring its redshift. As the universe expands, it stretches the light emitted by distant objects to longer, "redder" wavelengths. The farther and longer the light has traveled, the larger its redshift. In the new study, which has not yet been peer-reviewed, the team confirmed MoM-z14's redshift as 14.44 — larger than that of the previous record holder for farthest observed galaxy, JADES-GS-z14-0, at 14.18. Related: James Webb telescope sees 'birth' of 3 of the universe's earliest galaxies in world-1st observations MoM-z14 is fairly compact for the amount of light it emits. It's about 240 light-years across, some 400 times smaller than our own galaxy. And it contains about as much mass as the Small Magellanic Cloud, a dwarf galaxy that orbits the Milky Way.

It's also rich in nitrogen relative to carbon, much like globular clusters observed in the Milky Way. These ancient, tightly-bound groups of thousands to millions of stars are thought to have formed in the first few billion years of the universe, making them the oldest known stars in the nearby cosmos. That MoM-z14 appears similar could suggest that stars formed in comparable ways even at this very early stage in the universe's development. Though scientists still aim to confirm more high redshift galaxies, researchers expect to find even more candidates with the Nancy Grace Roman Space Telescope, an infrared telescope designed to observe a large swath of the sky, which is set to launch by May 2027. But JWST may break its own record again before then. "JWST itself appears poised to drive a series of great expansions of the cosmic frontier," the authors wrote. "Previously unimaginable redshifts, approaching the era of the very first stars, no longer seem far away."

Schouws et al/JWST: NASA, ESA, CSA, STScI, Brant Robertson (UC Santa Cruz), Ben Johnson (CfA), Sandro Tacchella (Cambridge), Phill Cargile (CfA) Listen to article 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 elements, but findings show this galaxy contains significantly more oxygen than anticipated, indicating rapid star formation and chemical enrichment. The breakthrough, reported by two independent research teams, provides a more precise distance measurement of the galaxy and challenges conventional timelines of galaxy evolution. Scientists highlight the synergy between the ALMA telescope and the James Webb Space Telescope (JWST) in pushing the boundaries of early cosmic discoveries. Experts say this finding could reshape our understanding of how galaxies formed and evolved in the universe's infancy.
