* '''Technosignature''' — Any "Observable Evidence" of "Extraterrestrial Technology" (Radio, Infrared, Laser, Atmospheric chemicals, or Megastructures).
* '''Dyson Sphere''' — (See Article 698). A "Hypothetical" "Shell" or "Swarm" that "Encloses" a "Star" to "Capture" its "Entire Energy Output."
* '''Matrioshka Brain''' — A "Megastructure" "Composed" of "Multiple Layers" of "Dyson Spheres," where each layer "Uses" the "Waste Heat" of the layer inside it to "Perform" **"Massive Computation."**
* '''Shkadov Thruster''' — (Stellar Engine). A "Megastructure" that "Uses" "Mirror-like Surfaces" to "Push" a "Star" through space (The 'Spaceship' is the 'Star').
* '''Kardashev Scale''' — (See Article 698). The "Measurement" of "Civilization Advancement" (Type I, II, III) "Based" on "Energy Use."
* '''Infrared Excess''' — The "Primary Signal" of a Dyson Sphere: "Detecting" "Thermal Radiation" from a star that is "Warmer" than "Expected" because the "Light" is "Being Captured and Re-emitted."
* '''Orbital Occultation''' — The "Anomalous" "Dimming" of a star (e.g. 'Tabby's Star') caused by a "Massive Artificial Object" "Passing" in front of it.
* '''Atmospheric Technosignatures''' — "Industrial Pollutants" (like 'CFCs' or 'NO2') found in the "Atmosphere" of an "Exoplanet."
* '''Stellar Disruption''' — "Evidence" of "Mining" (see Article 688) or "Dumping" of "Waste" into a "Star," "Changing" its "Spectral Signature."
* '''Dyson-Harrop Satellite''' — A "Hypothetical" "Megastructure" that "Extracts" "Energy" from the **"Solar Wind."**
