No Alien Signals Detected in 3I/ATLAS Scan
TL;DR
A team from SETI Institute and Breakthrough Listen used the Allen Telescope Array to scan 3I/ATLAS across a wide range of radio frequencies, filtering 74 million raw hits down to about 2 million candidates and then to 211 signals; none exhibited artificial signatures and all were attributed to radio-frequency interference. The result provides no evidence of alien technosignatures in this interstellar object but demonstrates that current technology can detect signals if present and supports continuing searches for technosignatures in future observations.
