US Edition'Previously Unimaginable': James Webb Telescope Breaks Its Own Record Again, Discovering Farthest Known Galaxy in the Universe
- The James Webb Space Telescope identified MoM-z14 as the most distant known galaxy, observed at a redshift of 14.44.
- Researchers led by MIT astrophysicist Rohan Naidu analyzed existing JWST images to confirm MoM-z14 surpasses the previous record redshift of 14.18 held by JADES-GS-z14-0.
- MoM-Z14 measures approximately 240 light-years across, making it about 400 times smaller than the Milky Way, and was detected during an intense phase of star formation occurring just 280 million years following the universe’s formation.
- The study was posted on arXiv on May 23, 2025, and University of Copenhagen astrophysicist Charlotte Mason remarked that the findings provide clear evidence of the existence of exceptionally bright galaxies in the universe.
- This discovery challenges previous theories about early galaxy formation and suggests JWST and the upcoming Nancy Grace Roman Space Telescope may reveal many more ancient galaxies soon.

Back to the Pictureable: James Webb Finds Galaxy 280 Million Years After Big Bang
The Space Telescope James Webb (JWST) once again surpassed its own record by identifying the most distant galaxy already observed. The new candidate is MoM-z14, visible only 280 million years after...
'Previously unimaginable': James Webb telescope breaks its own record again, discovering farthest known galaxy in the universe
The James Webb Space Telescope has broken its own record once again, spotting the most distant, early galaxy in the known universe. The new contender is MoM-z14, a galaxy visible just 280 million years after the Big Bang.
Shining Since the Dawn of Time: The James Webb Telescope Discovers the Most Distant Galaxy Ever Seen
A technological feat signed James Webb Since its commissioning in 2022, the James Webb space telescope (JWST) has changed our certainties. Thanks to its immense 6.5 meter mirror and its ultra-sensitive instruments capable of capturing infrared light, it probes the most remote ages in the universe, far beyond the capacities of its predecessors. Before him, Hubble had detected only one galaxy dating from the first 500 million years after the Big B…
