Missing nitrogen traced to deep Earth core in planetary formation simulations

Tokyo, Japan (SPX) Apr 14, 2025

A longstanding mystery in Earth science may finally have an answer: why Earth's rocky mantle contains so little nitrogen compared to other volatile elements. According to a new study from Ehime University, most of Earth's nitrogen may have sunk into the core during its formation, effectively hiding it from view for billions of years. During Earth's infancy, the planet was covered by a deep
