Ninth Planet, Extinct Aliens, and Dimming Stars

Hosts Phil Bowermaster and Stephen Gordon delve into some interesting recent space news.

Is there a ninth planet out there beyond Neptune? And even if not, what can we expect to discover out there in the deepest reaches of the solar system?

Meanwhile the lastest theory proposed to account for the Fermi Paradox is that The Aliens Are Extinct.

Okay, maybe. But then if that's the case, who is building those megatsructures out in deep space? (And even if there aren't any, just what the heck is going on with KIC 8462852?) 

Mysteries abound! Join us.
