Astrobiology

Astrobiology is an interdisciplinary field that investigates the origin, evolution, distribution, and future of life in the universe, combining the principles of astrophysics and cosmology with biology, chemistry, and geology. It applies the fundamental laws of physics to understand the conditions necessary for life to emerge and survive, while using the framework of astrophysics to identify potentially habitable planets and moons both within our solar system and around other stars. By studying the cosmic context for life, from the formation of stars and planets to the large-scale structure of the universe, astrobiology seeks to answer the profound question of whether humanity is alone in the cosmos.
