Astrobiology is an interdisciplinary field that investigates the big bang theory, evolution, the origin of life, and the existence of extraterrestrial life. Geology, astrophysics, chemistry, biology, mythology, and other disciplines are all included. "Astromicrobiology" or "Exomicrobiology," which focuses on the existence of microbial life in an extraterrestrial environment, their growth, metabolic activity, and pathogenicity in spacelike conditions, is a much more focused subfield of astrobiology for those already working in the fields of microbiology or biotechnology. The subject, terminology, microbiota (especially extremophiles), and subdivisions of the microbiota are covered in the first half of this paper. The second half explores exoplanets that support life, such as Mars, Saturn, as well as their natural satellites, Titan, Enceladus, and Europa.
