ALMA Telescope Data Powers First High-Frequency SETI Survey

Researchers from the University of Manchester have completed the first Search for Extraterrestrial Intelligence (SETI) survey using the Atacama Large Millimeter/submillimeter Array (ALMA) ^[1]. The study analyzed millions of stars for narrowband signals that could indicate technosignatures from advanced civilizations ^[1]. This search is significant because it explores higher radio frequencies beyond the traditional "water hole" spectrum usually monitored by astronomers ^[2].

By employing artificial intelligence, the team scanned massive datasets to detect patterns that suggest artificial origins ^[1]. Scientists believe that alien signals may be hiding in these unexplored high-radio channels ^[3]. While the initial survey did not confirm any signals, it successfully demonstrates ALMA's capability to search for complex communication patterns in deep space ^[2].
