"With Webb, we are able to see farther than humans ever have before, and it looks nothing like what we predicted, which is both challenging and exciting,"
"It's an incredibly exciting time, with Webb revealing the early Universe like never before and showing us how much there still is to discover"
A bright galaxy named MoM-z14 existed 280 million years after the Big Bang. The James Webb Space Telescope's Near-Infrared Spectrograph measured its redshift and wavelength shifts to date the galaxy. MoM-z14 exhibits higher-than-expected nitrogen abundances, indicating rapid chemical enrichment in some early galaxies. The galaxy's brightness and composition provide new constraints on models of early star formation and the timeline of reionization, when stellar light ionized primordial hydrogen. These observations challenge preexisting theoretical predictions and suggest more complex early-universe processes than previously assumed.
