Scientists Study 100 Possible Alien Signals as Arecibo’s Historic SETI Search Concludes

Scientists are studying 100 possible alien radio signals identified from Arecibo Observatory data, bringing the 21-year SETI@Home project to a close. Supported by millions of volunteers, the effort found no confirmed alien messages but set new sensitivity standards. Researchers say the findings will guide future searches using more powerful radio telescopes.Scientists are studying 100 possible alien radio signals identified from Arecibo Observatory data, bringing the 21-year SETI@Home project to a close.
