Cataloging Technosignatures: A NASA-Funded, Data-Driven Search for Intelligent Life Beyond Earth
To the point
Adam Frank and colleagues Jason Wright, Manasvi Lingam, and Ravi Kopparapu lead a science-based search for technosignatures on exoplanets by building an online library and identifying signs such as energy use, pollutants, and solar-panel spectra, while avoiding UFO talk and noting that light-speed delays make distant observations the practical path.
