Scientists have scanned the interstellar object 3I/ATLAS for alien signals using the Green Bank Telescope but found no evidence of artificial radio emissions, supporting the idea that it is a natural comet. Despite ongoing investigations and some anomalies noted by Avi Loeb, current data suggest 3I/ATLAS is likely a natural icy body rather than an alien probe.

During its closest approach to Earth, the interstellar comet 3I/ATLAS was observed by the Breakthrough Listen project for signs of alien technosignatures, but no credible signals were detected. Simultaneously, another team estimated the comet's size to be around 1 km based on its non-gravitational acceleration, confirming its natural cometary nature. The efforts highlight ongoing searches for extraterrestrial signals and detailed studies of interstellar objects.
