IAA 2026 Declaration Update Expands SETI to Technosignatures and Establishes International, Comprehensive Post-Detection Governance

To the point

Michael Garrett of the University of Manchester helped steer a 2026 update that expands the search for intelligent life beyond radio signals to technosignatures such as optical pulses and the infrared glow of megastructures, and establishes an internationally coordinated, patient process for independent verification, transparent disclosure, researcher protection, data archiving, and long‑term governance to guide humanity’s response.
