Technosignatures in Exoplanet Research: Expanding the Search for Intelligent Life

To the point

Technosignatures are signs of intelligent life beyond biology, such as laser or radio bursts, atmospheric chemicals, or infrared signatures from megastructures, and NASA treats them as part of the broader biosignature search alongside exoplanet studies, with leaders like Jill Tarter, Ravi Kopparapu, Jason Wright, Nick Siegler, and Dawn Gelino guiding initiatives such as NExSS that piggyback on existing observations to save costs while AI helps sift huge datasets and detect short‑lived or unusual signals, all in a hopeful push that a quantitative framework could reveal if something is out there.
