Astrobiology is a multidisciplinary scientific field that studies the possibility of life in the universe, including how life emerged on Earth. It involves the search for life beyond Earth, studying environments that could support life, and investigating interactions between planets and their stars. Astrobiologists, who may be experts in biology, astronomy, chemistry, and other fields, are beginning to address questions about what kind of environments can support life, what forms life could take on other planets, and what signs could indicate a planet is habitable or inhabited. Some astrobiologists are involved in the search for radio signals that could indicate extraterrestrial life. The field also includes studying how life arose and evolved on Earth, including the simplest forms of life and those that live in extreme conditions.
Key Takeaways:
- Astrobiology is an interdisciplinary scientific field that explores the possibility of life in the universe, including how life began on Earth and the potential for life on other planets.
- Astrobiologists study various aspects such as the environments needed for life to survive, the potential forms life could take on other planets, and the signs that could indicate a planet is habitable or has been inhabited by life at some point.
- The work of astrobiologists has significantly influenced how space agencies like NASA and the European Space Agency plan and conduct their off-world missions.
“Astrobiology is the field of science concerned with the study of life in the universe and attempting to solve the mystery of how life emerged on Earth. This includes the search for life beyond Earth, studying environments that could support life as well as investigating interactions between planets and their stars and exploring how this could influence life.”
