Look for microwave SETI at the end of the article.

Here's a link to the article:

"No definitive answer"?

How about no answer at all? Or how about an honest answer, that no one
really has a clue (and I mean that literally, as it is true literally).
We have lots and lots of ignorance, and not a whole lot more. And this
is true despite the fact that there is lots more actual data today. At
best, said data provides a foundation for extrapolating, it provides no
answer as to whether ET's exist, much less ET civilizations.

There's lots and lots of speculation, some small amount of it actually
based upon observation, but there are, as yet, no answers at all, much less definitive answers. And curiously, I don't see many stating the
simple, honest truth, that we simply do not know. And there is no reason
to think that better observations will change this.
