Wed. May 25, 2022 10:45 AM - 12:15 PM 304 (International Conference Hall, Makuhari Messe)

convener:Fujishima Kosuke(Tokyo Institute of Technology, Earth-Life Science Institute), convener:Hikaru Yabuta(Hiroshima University, Department of Earth and Planetary Systems Science), Seiji Sugita(Department of Earth and Planetary Science, Graduate School of Science Sciece, The University of Tokyo), convener:Misato Fukagawa(National Astronomical Observatory of Japan), Chairperson:Misato Fukagawa(National Astronomical Observatory of Japan), Hikaru Yabuta(Hiroshima University, Department of Earth and Planetary Systems Science)

Astrobiology is an interdisciplinary scientific field that studies the origin, evolution, distribution, and habitability of life in the universe. Scientists have long questioned how abiotic materials have developed into a biological system on Earth and elsewhere. However, we still face challenges in providing an in-depth scenario that can answer the above question. Thus, connecting the dots between astronomy, Earth and planetary science, chemistry, and biology are essential. JpGU astrobiology session will therefore stand as a cross-section for all the potential astrobiologists interested in the following research themes: 1) the formation and evolution of planetary systems, 2) the chemical evolution and geochemistry within our solar system, 3) understanding the origins and evolution of biomolecules and energy flow for life, and 4) development of life detection strategies for future exploration for life in the universe.
We are willing to facilitate exciting discussions that will connect the above themes to further envision Astrobiology's future.
