About
Hiroshi Naraoka is a pioneering geochemist and cosmochemist whose research focuses on the origin and evolution of organic matter in the solar system, with a particular emphasis on extraterrestrial materials. His major contributions lie in the development of cutting-edge analytical techniques for studying pristine samples returned from asteroids and comets. Notably, Naraoka led the organic analysis of samples from the Hayabusa2 mission, revealing the presence of diverse organic molecules on asteroid Ryugu, including amino acids and other prebiotic compounds that offer critical insights into the building blocks of life. His work on noble gas mass spectrometry for extraterrestrial micro-samples—enabling high-sensitivity isotope analysis of asteroid material—has been instrumental in advancing our understanding of solar system formation and the delivery of volatiles to Earth. With over 150 publications and thousands of citations, Naraoka’s impact is profound, and his achievements include leading the Hayabusa2 Initial Analysis Team for Organic Matter. His research continues to shape the field of astrobiology and planetary science, inspiring students and researchers to explore the chemical origins of life.
