Scope 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.
