Technosignatures as a Priority in Planetary Science [PDF]
Bulletin of the AAS, 2021 Are we alone? The study of technosignatures, physical manifestations of technology from extraterrestrial intelligences, is a rigorous astrobiological sub-discipline. The Planetary Science decadal should include searches for technosignatures alongside biosignatures in its recommendations for funding a robust astrobiology research portfolio.

Technosignatures Gap List Study
, 2022 Abstract: Motivation and Objective: The ExEP (Exoplanet Exploration Program) is a program within NASA’s Astrophysics Division whose charter includes identification and development of key technologies to enable the discovery of habitable worlds. We are following up on the 2018 NASA Technosignatures (TS) Workshop report to inform the ExEP with a thorough
