MoM-z14, as of August 2025, is 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. As part of 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 appears to be going through a time of high star formation giving off large amounts of ionizing photons which travel through a virtually dust free interstellar medium (ISM), though our observation would be from around 13.53 billion years ago. The surroundings of MoM-z14 are partially ionized. [1]
