IAU Commission F3 Astrobiology Meeting: Origins 2026 

[Formerly IAUS407]

Due to organizational issues, this meeting will no longer be held as an IAU Symposium as originally planned, but as a Commission F3 Astrobiology meeting.

Origins 2026 is an international conference jointly organized by the International Society for the Study of the Origins of Life – The International Astrobiology Society (ISSOL) and the Astrobiology Commission of the International Astronomical Union (IAU). 

The conference will bring together experts from a wide range of disciplines—including chemistry, biology, planetary science, and astrophysics—to explore the origins of life and planetary habitability on Earth and beyond. Hosted at the prestigious Museum National d'Histoire Naturelle and Sorbonne Université, the scientific program will highlight interdisciplinary research on the transition from non-living to living systems, early Earth environments, evolutionary processes, and the search for biosignatures in the universe.

The scientific program will feature the latest advances in prebiotic chemistry, the evolution of early life, and habitability within the Solar System and on exoplanets, alongside philosophical and historical perspectives. Special emphasis will be placed on the contributions of early-career researchers, with dedicated opportunities for visibility and exchange. This landmark event aims to strengthen international collaborations and advance our understanding of the emergence of life.
