MoM-z14 is currently the farthest known galaxy discovered in the universe with a redshift of z = 14.44 placing the galaxy's formation about 280 million years after the Big Bang. For the Cosmic Timeline, MoM-z14 would have been formed during the Reionization Era of the early universe, when neutral hydrogen began ionizing due to radiated energy from the earliest celestial objects.[1][2]
MoM-z14 is a remarkably luminous and compact galaxy. It has a mass of 108 solar masses making it similar in mass to the Small Magellanic Cloud (SMC). It is currently going through a time of high star formation giving of lots of ionizing photons which travel through a virtually dust free interstellar medium (ISM). The surroundings of MoM-z14 are partially ionized.[1]
Discovery
[edit]It was discovered on 16 May 2025 by Rohan Naidu with the James Webb Space Telescope (JWST).[1] Prior to the JWST space telescope, there was no telescopes with large enough mirrors to detect light coming from these distant galaxies. The Spitzer telescope was a infrared telescope but was not large enough to detect MoM-z14. With the James Webb Space Telescope size and primary mission to study the assembly of galaxies, MoM-z14 was able to be detected.[3]
