Researchers were looking for signs of alien technology in a star system very similar to our own solar system, reports Forbes. Scientists used the Allen Telescope Array in California, USA, to search for artificial radio signals potentially created by extraterrestrial civilizations in the TRAPPIST-1 star system. Located in the Milky Way, about 41 light-years away from Earth, TRAPPIST-1 is often referred to as “Solar System 2.0” due to its similarities to our own Solar System. The results of the study have been accepted for publication in the Astronomical Journal, according to Forbes. The TRAPPIST-1 system consists of a red dwarf star and seven rocky planets, all roughly Earth-sized. This is the largest number of terrestrial planets orbiting a single star. Some of these planets are within the habitable zone of the red dwarf, meaning they could potentially support liquid water on their surfaces—raising the possibility that life, including intelligent and technologically advanced life, could exist there. Given these conditions, scientists decided to search for radio signals that might indicate alien technology. Specifically, they looked for radio transmissions that extraterrestrial beings might send between planets. It is generally thought that it might be easier to detect signs of alien technology than to find direct evidence of alien biological life. For 28 hours, scientists used the radio telescope to monitor the TRAPPIST-1 system, marking the longest continuous search for alien radio signals in this star system. Of the vast number of radio signals detected—2,264 in total—none were artificial in origin, indicating that no signs of alien technology were found. Although this particular search for potential alien activity in TRAPPIST-1 was unsuccessful, the study yielded valuable data that may aid future searches for extraterrestrial civilizations. Scientists say they are approaching the point where they could detect the same types of radio signals that humans send into space, which could improve the chances of identifying alien intelligence. Currently, researchers are limited to detecting radio signals similar to those humans transmit. However, more powerful radio telescopes will soon be operational, enabling the detection of weaker signals from potential alien civilizations communicating with their spacecraft. One example is the Square Kilometre Array, a $2.2 billion project consisting of two arrays of radio dishes in southern Africa and western Australia, which is set to begin operations soon. This advanced telescope will be capable of detecting faint radio signals that might originate from extraterrestrial civilizations.
