Researchers uncover nitrogen's origin and early evolution on Earth

Researchers from the University of Science and Technology of China have uncovered key insights into the origin and early evolution of nitrogen on Earth. They studied the fractionation of nitrogen isotopes during the formation of terrestrial planets, revealing that both early planetesimal processes and late accretion of volatile-rich materials contributed to Earth’s nitrogen composition. This research provides a new understanding of how nitrogen, essential for life, accumulated on our planet.
