The Serendipitous Detection of Technosignatures in Exoplanet Characterization Observations
Dr. Thomas Beatty (Steward Observatory-University of Arizona)

The extremely high contrast ratios afforded by possible upcoming missions like LUVOIR and HabEx mean that we will also be able to directly detect certain techosignatures in planetary systems nearby the Sun. First, these missions will be able to spectroscopically identify the presence of nightside city lights on Earth-like planets over a range of surface urbanization levels. Second, they will be able to detect large-scale interplanetary spaceflight using fusion torchships in nearby systems via the spectroscopic signatures of the hot fusion exhaust. Both of these signals will be detectable in planned atmospheric characterization observations, and by piggy-backing on the atmospheric programs we will be able to place meaningful constraints on the presence of these technosignatures in nearby planetary systems.
