Scientists use Allen Telescope Array to search for radio signals in the TRAPPIST-1 star system

Scientists look for alien technology from the TRAPPIST planets

Since its discovery eight years ago, the TRAPPIST-1 star system has excited astronomers because of its potential for supporting life. Around this cool red dwarf are seven rocky, Earth-sized exoplanets, some of which are at the right distance to possibly have air and water.

Are nearby planets sending radio signals to each other?

Researchers have developed a new method using the Allen Telescope Array to search for interplanetary radio communication in the TRAPPIST-1 star system.

Alien Eavesdropping: How SETI’s Latest Technology Scoured TRAPPIST-1 for Otherworldly Communications

Scientists at SETI and Penn State deployed the Allen Telescope to probe TRAPPIST-1 for alien signals over 28 hours. Utilizing planet-planet occultations and enhanced scanning technology, they identified potential signals, none of which were extraterrestrial, but the methods developed promise future success.

Scientists at the SETI Institute and partners from Penn State University used the Allen Telescope Array (ATA) to search for signs of alien technology in the TRAPPIST-1 star system.

Scientists Begin Search For Radio Signals From ‘Solar System 2.0’

The longest single-target search for radio signals from TRAPPIST-1 — a star system with seven planets just 41 light-years away — has begun at the Allen Telescope Array.
