Astrobiology is closely related to (but distinct from) exobiology: by definition, exobiology is focused on the study of life beyond Earth, including human spaceflight and the prospects for human exploration of other planets. Research in astrobiology builds on interdisciplinary collaborations between experts in disciplines such as astronomy, astrochemistry, the Earth sciences, and the life and environmental sciences. The scope of the research includes the exploration of potentially habitable environments...
