No Technosignatures Detected in Interstellar Comet 3I/ATLAS; Study Sets Upper Limits on Transmitter Power
To the point
Dr. Sofia Sheikh and Valeria Garcia Lopez report that a radio search of the interstellar comet 3I/ATLAS found no technosignatures, with all candidate signals traced to Earth and transmitter power limited to about 10–110 watts, underscoring that interstellar objects are valuable for distinguishing natural from artificial signals as more such objects are discovered.
