Supermassive Stars Explain Nitrogen Boost in GN-z11
Introduction: A Nitrogen Enigma in the Early Universe Astronomers have long suspected that the first galaxies formed with simple chemical footprints. Yet recent observations of GN-z11, a galaxy seen as it was when the universe was just about 420 million years old, reveal unusually high nitrogen levels. This surprising finding challenges conventional models of early…
