Why has the Search for Extraterrestrial Life (SETI) movement switch to sending signals instead of looking for them? A good answer would be that so many of the strange signals received, like the fast radio bursts (FRBs), are usually proven to have a natural cause – fast radio bursts are thought to be the result of colliding neutron stars or powerfully magnetic neutron stars known as magnetars. However, one signal has defied natural explanations – the famous WOW! signal named for the red exclamation written by a stunned astronomer on the computer printout which revealed it. Now, another astronomer using a new technique believes he’s traced the WOW! signal back to its star -- and it appears to have a habitable “Goldilocks” zone where an Earth-like planet could be populated with Earth-like beings sending a signal to what they think is a planet like theirs. Wow!
