Overview
Archive NoteMoM-z14 was detected in the COSMOS field with Webb's NIRCam imager and subsequently confirmed with the NIRSpec spectrograph.
Its redshift of 14.44 corresponds to light emitted roughly 280 million years after the Big Bang and travelling for around 13.5 billion years. Its unexpectedly high brightness and chemical enrichment inform models of early star formation and reionization.

Evidence & ReferencesVerification basis and limitations
VerifiedThe record conclusion has sufficient verification support.
Basis: direct confirmation by an authority
NASA and ESA/Webb confirm that the galaxy MoM-z14 has a spectroscopically measured cosmological redshift z = 14.44, corresponding to a glimpse of the universe roughly 280 million years after the Big Bang. Redshift is dimensionless; it is not the same as light-travel time or present-day proper distance. The announcement date is not a galaxy formation date.
