## Body

### Core Definition and Scope
Astrobiology is the multidisciplinary study of life's origins, evolution, distribution, and future in the universe. It integrates biology, astronomy, chemistry, and geology to investigate how life arises, adapts, and survives in diverse environments, from Earth's extremes to extraterrestrial worlds. The field encompasses the search for biosignatures, the study of habitable zones, and the analysis of celestial mechanics that influence planetary environments.

### Historical Development
Emerging as a distinct field in the mid-20th century, astrobiology builds on historical works such as Carl Sagan's planetary science research and the Viking Mars missions' biosignature experiments. The discovery of exoplanets in the 1990s and advancements in extremophile biology expanded its scope, while institutions like the SETI Institute (founded 1984) and NASA's Astrobiology Program formalized its research framework.

### Subfields and Specializations
