Astrobiology

Is there life outside of Earth? Is there a future for humankind in outer space? These are but a few among the many questions that this field of science attempts to answer. Exobiology (also Astrobiology) is an interdisciplinary field that combines astronomy, biology and geology to study the origins, evolution, distribution and future of life in the universe. Thus, it is concerned with how life began, the search for extraterrestrial life, the effects of outer space on living organisms, the future of the Earth, and the possible habitability elsewhere in the universe .
