Astronomers Have Detected a Galaxy Millions of Years Older Than Any Previously Observed
Researchers estimate that MoM z14 was created 280 million years after the Big Bang, 10 million years earlier than the previous most primitive galaxy recorded.
In a preprint study, still awaiting peer review and publication in a journal, astronomers describe this primitive galaxy, giving it the name MoM z14. No one expected the James Webb Space Telescope to have the potential to observe things so close in age to the Big Bang just three and a half years after launch. The James Webb Space Telescope was able to determine that MoM z14 is 50 times smaller than the Milky Way, and also detected the presence of nitrogen and carbon in the galaxy.
