Expanding the SETI Frontier: Broader Technosignatures, Global Collaborations, and a Next-Generation Very Large Array

To the point

Researchers are expanding the hunt for alien life beyond radio waves to a wide range of technosignatures—such as atmospheric gases, lasers, and structures around stars—driven by new collaborations and large surveys, with leaders like Andrew Siemion and Jill Tarter guiding efforts that build on Breakthrough Listen and projects like PANOSETI and Laser SETI to pursue robust, carefully interpreted evidence across a much larger portion of the universe.
