History of Astrobiology

Early Speculation (Antiquity-1800s)

• 4th Century BCE: Aristotle proposes “spontaneous generation” theory
• 1600s: Christiaan Huygens speculates about extraterrestrial life in Cosmotheoros
• 1877: Giovanni Schiaparelli’s “canali” observations spark Mars life debates

Modern Foundations (1900-1990s)

• 1953: Miller-Urey experiment demonstrates abiotic amino acid formation
• 1976: Viking landers conduct first life-detection experiments on Mars
• 1996: ALH84001 meteorite controversy reignites Mars fossil discussions

Institutionalization (2000s-Present)

• 2001: NASA establishes Astrobiology Institute
• 2015: Discovery of liquid water on modern Mars
• 2023: James Webb Telescope detects potential biosignatures on exoplanets
