* '''Astro-Archaeology''' — (Techno-archaeology). The "Sub-field" of archaeology that "Searches" for "Physical Evidence" of "Past" or "Present" "Extraterrestrial Civilizations."
* '''Technosignature''' — (See Article 686). Any "Observable Evidence" of "Advanced Technology" (like 'Dyson Spheres' or 'Orbital Mirrors') that "Could" be "Detected" by "Telescopes."
* '''Artifact''' (Alien) — A "Human-made" (or Alien-made) "Object" "Found" in space that "Shows" "Signs" of "Artificial Origin."
* '''Dyson Swarm''' — (See Article 698). A "Large Collection" of "Solar-power Satellites" "Orbiting" a star, "Potentialy" "Detectable" by their **"Waste Heat"** (Infrared signature).
* '''SETA''' — (Search for Extraterrestrial Artifacts). The "Sub-discipline" "Specifically" "Focused" on "Finding" "Alien Probes" or "Junk" in our "Solar System."
* '''Necrosignature''' — The "Hypothetical" "Evidence" of a "Civilization" that has "Destroyed Itself" (e.g. 'Atmospheric pollution' from 'Nuclear war' found on an exoplanet).
* '''Bracewell Probe''' — A "Self-replicating" "Alien Probe" "Designed" to "Wait" in a "Solar System" until it "Detects" "Intelligence" and then "Initiate Contact."
* '''Megastructure''' — (See Article 586). A "Massive" "Artificial Construction" in space (like 'Ringworlds' or 'Stellar Engines').
* '''Great Silence''' — (See Article 689). The "Lack of Evidence" for aliens, which **Astro-Archaeology** "Attempts" to "Explain" by "Suggesting" they "Left" "Monuments" rather than "Signals."
* '''Clarke’s Third Law''' — (See Article 669). "Any sufficiently advanced technology is indistinguishable from magic." (The "Archaeological Challenge" of "Recognizing" alien tech).
