The JWST Advanced Deep Extragalactic Survey (JADES) program led to the discovery of this new galaxy dubbed JADES-GS-z14-0.

“The instruments on Webb were designed to find and understand the earliest galaxies, and in the first year of observations as part of the JWST Advanced Deep Extragalactic Survey (JADES), we found many hundreds of candidate galaxies from the first 650 million years after the big bang,” said Stefano Carniani from Scuola Normale Superiore in Pisa, Italy.

They stumbled across this exceptional galaxy in October 2023 while scouring through the vast pool of JADES program data.
