Scientists Scan TRAPPIST-1 for Interplanetary Radio Signal Using Allen Telescope Array

Scientists at Penn State and the SETI Institute have developed a new method to search for interplanetary radio signals from planets in the TRAPPIST-1 system. Using the Allen Telescope Array, they scanned this system for nearly 28 hours but did not find evidence of alien communication. This project, however, has introduced a new way of detecting potential signals, part...
