Do you even SETI ANON?! I’ve been processing data for longer than a lot of you have been out of diapers. Millions of home PCs helped uncover 100 mysterious signals from space… For 21 years, millions of volunteers around the world lent their home computers to UC Berkeley’s SETI@home project, a massive crowdsourced effort to sift through radio data from the now-collapsed Arecibo Observatory in Puerto Rico in search of signals from extraterrestrial civilizations. Using this distributed network, scientists generated some 12 billion initial signal detections, then used supercomputers and careful filtering to weed out interference from sources like radio and TV broadcasts and even everyday appliances. That long process has narrowed the field to about 100 radio signals that researchers consider “worth a second look.” Since mid-2025, the team has been re-observing these promising candidates with China’s enormous Five-hundred-meter Aperture Spherical Telescope (FAST), hoping to spot any repeat signals that might hint at intelligent origins. So far, no clear evidence of alien life has emerged, leaving project leaders both proud of the unprecedented sensitivity they achieved and disappointed not to have found a “smoking gun.” Still, scientists say SETI@home has been far from a failure: it proved that volunteer computing can power large-scale space research and helped define new benchmarks for how faint a signal we can reliably detect. It also underscored how easily real signals can be lost amid radio noise, raising concerns that overly aggressive filtering might accidentally discard something important. Looking ahead, the team hopes their lessons will guide a successor project that takes advantage of today’s faster computers and wider internet bandwidth—though they note that staff and funding remain major obstacles. And somewhere in that mountain of old data, they admit, there is still a chance that a missed alien signal is hiding just out of reach. References (APA style) Tangermann, V. (2026, January 16).
