Space Scientists use the Allen telescope to search for radio signals outside the solar system in the TRAPPIST-1 star system. Through a 28-hour study, more than 11,000 signal candidates were analyzed, but none were confirmed to be of extraterrestrial origin. This research improves methods for future searches, aimed at detecting signals between planets. The TRAPPIST-1 system, with seven Earth-like planets, is crucial in the search for potential clues to extraterrestrial life and technology.
