[M-IS07] Astrobiology

Mon. May 27, 2024 5:15 PM - 6:45 PM Poster Hall (Exhibition Hall 6, Makuhari Messe)

convener:Kosuke Fujishima(Tokyo Institute of Technology, Earth-Life Science Institute), Yohey Suzuki(Graduate School of Science, The University of Tokyo), Yuka Fujii(National Astronomical Observatory of Japan), Kosuke Kurosawa(Graduate school of Human Development and Environment, Kobe University)

Astrobiology is an interdisciplinary scientific field studying the origin, evolution, distribution, and habitability of life in the universe. Scientists have long questioned the origins and transfer of key elements and materials that form biological systems on Earth and beyond. Despite years of research, a thorough explanation for these phenomena has yet to be achieved. Thus, it is crucial to establish connections between astronomy, Earth and planetary science, chemistry, and biology. These fields offer unique insights into the dynamics of the universe, the complex systems that govern exoplanets, the solar system and the fundamental building blocks of life. By linking these disciplines, we can gain a more comprehensive understanding of the world around us and push the boundaries of scientific discovery. The JpGU astrobiology session provides an overview for astrobiologists interested in various research themes, including but not limited to, planetary system formation and evolution, exoplanetary surface environment and biosignatures, chemical evolution and geochemistry in the solar system, origins of biomolecules for life, and life detection strategies for space exploration. We are willing to facilitate informative discussions concerning the above themes, which aid in envisioning the future direction of astrobiology.
