Exobiology, also known as astrobiology, is the study of life on outer planets and in space. This interdisciplinary field focuses on the search for extraterrestrial life and the conditions that could support it. Exobiologists investigate how life might arise and evolve in environments beyond Earth, including on planets, moons, and other celestial bodies. They study the potential habitability of these environments by examining factors such as temperature, radiation, and the presence of water and organic compounds. Exobiology combines aspects of astronomy, biology, and chemistry to explore questions about the origin of life, its potential distribution in the universe, and how it may adapt to different conditions. This field also contributes to understanding how life on Earth might respond to changes in its environment and the potential risks and benefits of space exploration.
