Technosignatures: Expanding the Search for Extraterrestrial Intelligence
To the point
Technosignatures—signs of intelligent life beyond Earth such as laser or radio signals, unusual atmospheric chemicals, or the infrared glow of megastructures—are pursued through a broad, AI-assisted, multi-wavelength search that piggybacks on exoplanet observations, guided by NASA programs and researchers like Jill Tarter and Jason Wright.
