No Technosignatures Detected from Interstellar Comet 3I/ATLAS in Green Bank Telescope Observations
To the point
Benjamin Jacobson-Bell led a search for signals from alien technology from interstellar comet 3I/ATLAS with the Green Bank Telescope and found no evidence of such signals in the 1–12 GHz range, achieving sensitivity down to about 0.1 watt and showing that rapid, repeatable tests will help distinguish natural space phenomena from technology as more interstellar visitors arrive.
