Are nearby planets sending radio signals to each other?
A new technique allows astronomers to home in on planets beyond our solar system that are in line with each other and with Earth to search for radio signals similar, for example, to ones used to communicate with the rovers on Mars. Penn State astronomers and scientists at the SETI Institute spent 28 hours scanning the TRAPPIST-1 star system for these signs of alien technology with the Allen Telescope Array. Although the team didn’t find any evidence of extraterrestrial technology, their work introduced a new way to search for signals in the future.
