Extraterrestrial radio signals investigated

A curious radio signal picked up by a Russian telescope is probably not a transmission from an extraterrestrial civilisation, but astronomers in California are taking a second look anyway, the SETI Institute said. A group of Russian astronomers last year detected what appeared to be a non-naturally occurring radio signal in the general location of a star system 94 light-years from Earth. SETI astronomers have spent the last two nights using an array of radio telescopes in California to study the suspect star, HD 164595, which has one known planet in orbit. Aug 31, 2016
