According to a report by Good News Network, NASA's James Webb Space Telescope confirmed a bright galaxy called MoM-z14 that existed about 280 million years after the Big Bang. The confirmation used spectroscopy, which helps researchers verify what they're seeing and place it accurately in cosmic time.
Researchers say Webb is revealing more surprisingly bright early-universe galaxies than many pre-launch models predicted, opening new questions about how the first generations of stars formed and enriched galaxies with elements like nitrogen.
