Robust Exoplanet Life Detection: Gaseous, Surface Reflectance, and Temporal Biosignatures Across Contexts
To the point
Advanced telescopes will search habitable exoplanets for life by seeking three kinds of evidence—gaseous biosignatures in the atmosphere, surface reflectance clues, and temporal changes in gases or surfaces—while evaluating them within the planet’s context to avoid mistaking abiotic processes for life.
