Xenobiology also known as Xenology or Astrobiology is defined as the study of the origin, evolution, distribution, and future of life in the galaxy and, by extention, the universe. This interdisciplinary field encompasses the study of habitable environments in the galaxy, prebiotic chemistry, laboratory and field research into the origins and early evolution of life, and studies of the potential for life to adapt to challenges in both deep space and on planets.
Astrobiology makes use of chemistry, biology, molecular biology and other such fields to investigate life on undiscovered (theorectical) or newly discovered worlds. It also helps scientists recognize biospheres that are unusual and would otherwise be dismissed as places where life would be impossible.
There is a sub-division of the Imperial Science and Research Department devoted to this study.
