convener:Kensei Kobayashi(Department of Chemistry and Biotechnology, Faculty of Engineering, Yokohama National University), Masatoshi Ohishi(Astronomy Data Center, National Astronomical Observatory of Japan), Hikaru Yabuta(Hiroshima University, Department of Earth and Planetary Systems Science), Joseph Kirschvink(Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, CA, USA), Chairperson:Joseph Kirschvink(Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, CA, USA), Chairperson:Kensei Kobayashi(Department of Chemistry and Biotechnology, Faculty of Engineering, Yokohama National University)

Astrobiology is a new interdisciplinary science field that intends to address the origins, evolution, distribution and destiny of life on Earth and elsewhere in the universe. In this session, every topic of astrobiology will be discussed, including cosmic evolution, primitive Earth environments and origins of life, coevolution of life and Earth, life in extreme environments, etc.
