We’ve Been Searching for Aliens the Wrong Way. That’s All About To Change. . .

We’ve been looking for messages from the stars ever since Frank Drake pointed the Green Bank radio telescope at Tau Ceti and Epsilon Eridany 65 years ago. He saw nothing that couldn’t be explained by natural causes. Nor have the much more extensive SETI surveys conducted since. So, maybe there are no alien signals to see. Or maybe we need to update how we search for them. We have, after all, learned an awful lot since 1960—both about the galaxy and about observing the galaxy.
