Africa-Press – Mauritius. <\/strong><\/span>A team of international researchers, led by Kyoto University and including scientists from the University of Hawai\u2019i at Ma\u0304noa, has discovered that micrometeorites from distant icy celestial bodies in the outer solar system were likely responsible for ferrying essential nitrogen compounds to the early Earth.<\/p>\n

The latest study, titled \u201cInflux of nitrogen-rich material from the outer Solar System indicated by iron nitride in Ryugu samples,\u201d explores the intriguing possibility that the nitrogen compounds transported near Earth, particularly ammonium salts, played a crucial role in the formation of life on our planet.<\/p>\n

Ryugu, a small asteroid orbiting the sun, became the focus of the research as the Japan Aerospace Exploration Agency\u2019s Hayabusa 2 spacecraft brought back samples from its surface in 2020.<\/p>\n

Rich in carbon and marked by significant space weathering, Ryugu offered scientists a unique opportunity to investigate the cosmic origins of materials near Earth\u2019s orbit.<\/p>\n

Utilizing electron microscopy, researchers closely examined Ryugu samples, revealing tiny minerals composed of iron and nitrogen (iron nitride: Fe4N) on their surfaces. The breakthrough came when the scientists proposed that micrometeorites, carrying ammonia compounds, collided with Ryugu.<\/p>\n

These collisions triggered chemical reactions on magnetite, a key component of the asteroid\u2019s composition, leading to the formation of iron nitride.<\/p>\n

Lead author Toru Matsumoto, an assistant professor at Kyoto University, explained that the iron nitride was observed on the surface of magnetite, which undergoes changes when exposed to the harsh space environment.<\/p>\n

The loss of oxygen atoms from the magnetite\u2019s surface, caused by solar wind and micrometeorite impact, results in the formation of metallic iron. This iron readily reacts with ammonia, creating ideal conditions for the synthesis of iron nitride.<\/p>\n
