How to spotlight revolutionary Technosignatures now from 31 Sun-like Stars?
A Search for Technosignatures Around 31 Sun-like Stars with the Green Bank Telescope at 1.15-1.73 GHz Technosignatures are analogous to biosignatures in that they are a detectable sign of extant or extinct life Searches for technosignatures are logically continuous with the search for biosignatures as part of astrobiology. Technosignatures represent any sign of technology that we can use to infer the existence of intelligent life elsewhere in the universe. The search for technosignatures is thus broad, encompassing much of astronomy. Compared to biosignatures, technosignatures might therefore be more ubiquitous, more obvious, more unambiguous, and detectable at much greater (even extragalactic) distances. We conducted a search for technosignatures in April of 2018 and 2019 with the L-band receiver (1.15-1.73 GHz) of the 100 m diameter Green Bank Telescope. These observations focused on regions surrounding 31 Sun-like stars near the plane of the Galaxy. We present the results of our...
