JWST Finds Most‑Distant Galaxy (MoM‑z14) at 280 Myr; Webb and Chandra See Cluster Assembling by ~1 Gyr
JWST has detected MoM‑z14, the most distant galaxy yet observed, whose light dates to roughly 280 million years after the Big Bang. Combined JWST and Chandra data also show a galaxy cluster beginning to assemble about one billion years after the Big Bang, implying more rapid early structure growth.
