What field of science investigates ideas about possible extraterrestrial org ins of life?

The field of science that investigates ideas about possible extraterrestrial origins of life is called astrobiology. It explores the conditions under which life might arise elsewhere in the universe, the potential for microbial life on other planets, and the implications for our understanding of life's existence beyond Earth. Astrobiologists study extreme environments on Earth, the chemistry of life, and the potential habitability of other celestial bodies.
