Are We Missing Alien Signals?

What if alien life has been signaling us for centuries, and we’ve missed it?

Astrophysicist Simon Steel works with the @SETIInstitute to detect radio waves from intelligent life across the galaxy. The Search for Extraterrestrial Intelligence (SETI) scans deep space for radio waves that could come from civilizations with technology like ours. But the challenge? Distinguishing those rare signals from natural ones like black holes or lightning. What if the universe has been talking all along, and we’re only just learning how to listen?
