The astrobiological search for remotely detectable evidence of life involves an effort to understand a broad range of plausible biosignatures that could arise in extraterrestrial environments. Technology is one possible consequence of planetary-scale life, which could generate “technosignatures” that could be abundant, long-lived, highly detectable, and unambiguous compared to some biosignatures. This includes the search for technosignatures in exoplanetary systems as well as the possibility of finding technosignatures in the solar system. This session welcomes any theoretical, instrumental, observational, or data analysis ideas for characterizing and detecting technosignatures. Emphasis will be placed on methods that are relevant to current and future exoplanet observations with facilities such as space- or ground-based telescopes, ongoing solar system exploration missions, and any other analyses of data from existing Earth or space observations.
