JWST Shatters Records Again: Oldest Galaxy Ever Discovered

The James Webb Space Telescope (JWST) has once again broken its own record, detecting the galaxy MoM z14, a cosmic marvel existing a mere 280 million years after the Big Bang—13.52 billion years ago. This discovery surpasses expectations, as scientists didn't anticipate JWST finding such ancient galaxies at this stage of its mission. MoM z14 boasts a redshift of z=14.44, exceeding the previous record holder, JADES-GS-z14-0 (z=14.32). Researchers determined MoM z14 is about 50 times smaller than the Milky Way and detected emission lines indicating the presence of nitrogen and carbon, suggesting a young galaxy with a rapidly increasing star formation rate. This discovery hints at the possibility of even older galaxies in the early universe waiting to be found.
