Alarmingly, a team of scientists propose that every flight you take could be alerting alien civilizations to our existence. I must apologise now as I pack for a flight out to Mexico in a few days! The new research reveals that airport radar systems from Heathrow to JFK are unintentionally broadcasting powerful signals up to 200 light years into space, that’s far enough to reach over 120,000 star systems that might harbor intelligent life! These “accidental technosignatures” would appear obviously artificial to any aliens with technology similar to ours, potentially making every takeoff and landing an announcement that we’re here!
