According to numerous pop sci outlets, the Wow! Signal is a comet in a strange orbit around the sun. But according to experts, this explanation just doesn't fit the relevant data…

If there was a thriving alien civilization on one of the best candidates for life in our stellar neighborhood, we missed them by well over a billion years...

Just because we're very unlikely to hear from aliens doesn't mean we shouldn't at least try to listen.

Oddly, this is a case when a few signals would make a better case for alien contact than hundreds.

Could an alien civilization set up a way to communicate with us more visually than just sending a laser or microwave broadcast?

Based on the premise of SETI, if we do start talking to aliens, the ensuing conversation could get awkward very quickly...

Dr. Jill Tarter of SETI weighs in on the Wow! Signal for Weird Things.

Could we have already been contacted by aliens and just don't know it yet?
