 The source discusses the groundbreaking astronomical discovery of oxygen in JADES-GS-z14-0, the most distant galaxy ever detected, observed just 300 million years after the Big Bang. This finding, made possible by the James Webb Space Telescope (JWST), challenges existing models of early galaxy formation because oxygen, a heavy element, suggests that massive stars had already formed and died, enriching the cosmos much faster than anticipated. The episode explores how the presence of oxygen confirms vigorous star formation and provides vital clues about the chemical evolution of the universe and the process of reionization. Ultimately, this discovery aids in understanding the origins of cosmic elements and the rapid development of early cosmic structures.
