* '''Biosignature''' — "Any" "Measurable" "Property" of "A Planet" that "Provides Evidence" of "Life": "Chemical," "Physical," "Morphological," or "Spectral."
* '''Technosignature''' — (See Article 704). "A Biosignature" "Specific" to "Technological" "Civilization": "CFCs," "Radio Signals," "Laser Pulses," "Dyson Sphere" "Heat."
* '''Spectroscopy''' — "The Technique" of "Analyzing" "Light" to "Determine" "The Chemical Composition" of "An Atmosphere" — "The Primary Tool" for "Remote Biosignature Detection."
* '''Transmission Spectroscopy''' — "Analyzing" "Starlight" "Filtered" through "A Planet's Atmosphere" as "It Transits Its Star" — "Reveals" "Atmospheric Chemistry."
* '''The Vegetation Red Edge''' — "A Sharp" "Increase" in "Reflectance" at "700–740nm" produced by "Chlorophyll" — "A Potential" "Biosignature" for "Photosynthetic Life."
* '''False Positive Biosignatures''' — "Abiotic Processes" that "Mimic" "Biosignatures": "Photolysis" (can produce "O₂"), "Volcanism" (can produce "Methane"), "Comets" (can deliver "Organics").
* '''Contextual Biosignatures''' — "The Idea" that "No Single" "Biosignature" is "Definitive" — "Life Is" "Best Detected" by "Multiple" "Consistent Indicators."
* '''The James Webb Space Telescope''' (JWST) — "Launched" "2021": "The First" "Telescope" with "The Sensitivity" to "Detect" "Biosignatures" in "The Atmospheres" of "Some" "Rocky Exoplanets."
* '''TRAPPIST-1e''' — "One" of "The Most" "Studied" "Potentially Habitable" "Exoplanets" (see Article 756): "A Key" "Target" for "Biosignature Searches."
* '''The 'Pale Orange Dot'''' — "What" "Earth Would Look Like" from "Light-Years Away" — "Detecting" "Its Own" "Biosignatures" as "A Calibration" for "Exoplanet Searches."
