Technosignatures are observational manifestations of technology, particularly those that could be detected through astronomical or other means. Possible technosignatures include waste heat, artificial illumination, artificial atmospheric constituents, artificial surface constituents, stellar pollution, non-terrestrial artifacts, and megastructures. This workshop welcomes discussion of this broad set of technosignatures, as well as any others that could conceivably be detected by a current or future NASA mission.

NASA’s recent interest in technosignatures resulted in the convening of a technosignatures workshop in 2018, which produced a report that defined the state of the field and emerging opportunities. The 2018 workshop represented a significant step in NASA’s astrobiology strategy by emphasizing the connection between the search for life on exoplanets and the possibility of detecting signs of extraterrestrial technology.

TechnoClimes continued the momentum of the previous NASA workshop on technosignatures by holding a focused 5-day discussion with the goal of delivering a research agenda on technosignatures to the broader community.
