Viroids-First—A Model for Life on Earth, Mars and Exoplanets
The search for extraterrestrial life, recently fueled by the discovery of exoplanets, requires defined biosignatures. Current biomarkers include those of extremophilic organisms, typically archaea.

A More Comprehensive Habitable Zone for Finding Life on Other Planets
The habitable zone (HZ) is the circular region around a star(s) where standing bodies of water could exist on the surface of a rocky planet. Space missions employ the HZ to select promising targets for follow-up habitability assessment.

Finding extraterrestrial life using ground-based high-resolution spectroscopy [PDF]
Exoplanet observations promise one day to unveil the presence of extraterrestrial life. Atmospheric compounds in strong chemical disequilibrium would point to large-scale biological activity just as oxygen and methane do in the Earth's atmosphere.
