The two newfound galaxies, dubbed GLASS-z12 and GLASS-z10, existed approximately 350 and 450 million years after the Big Bang. GLASS-z12 (redshift of 12.5) and GLASS-z10 (redshift of 10.5) are captured in these Webb images of the outer regions of the galaxy cluster Abell 2744. Image credit: NASA / ESA / CSA / T. Treu, UCLA. GLASS-z12 and GLASS-z10 were spotted in the flanking field of the Hubble Frontier Fields cluster Abell 2744, a group of roughly...
