Astrobiology
Contributed by: Christie
  • 1. Astrobiology is an interdisciplinary scientific field that focuses on the study of the origin, evolution, distribution, and future of life in the universe. It combines principles and techniques from biology, chemistry, physics, geology, astronomy, and other disciplines to investigate the potential for life beyond Earth. Astrobiologists explore extreme environments on Earth that mimic conditions found elsewhere in the solar system or universe, search for habitable exoplanets, study the potential for microbial life in space, and investigate the possibility of extraterrestrial intelligence. By studying astrobiology, scientists seek to address fundamental questions about the nature of life, the conditions required for life to exist, and the likelihood of finding life beyond our planet.
