NASA is supporting a new project to search the universe for signs of technology that may provide evidence of intelligent life. The U.S. space agency has approved a financial award for researchers to look for evidence of progressive technology on other planets in the universe. Scientists call such evidence technosignatures. NASA describes technosignatures as signs or signals, which if observed, would allow us to infer the existence of technological life elsewhere in the universe. The best-known technosignatures are radio signals that scientists have identified coming from outer space.
