This month's "Are We Alone" podcast segment Skeptic Check is now online, where astronomer Seth Shostak and I talk about the purported jovian planet that might or might not exist in the cold depths of the solar system out past Neptune. We talk about the science of such a world, and how the media perhaps puffed this piece past a proportionate planetary propriety.

Probably.
