I hate to make the obvious jokes, so I’ll simply say I was on this week’s Skeptic’s Guide to the Universe talking about methane on Mars and the tilt of Uranus. I’m glad they invited me on; I hadn’t heard of either of these stories until Steve Novella alerted me to them before we did the interview.
Basically, a new hypothesis has come out that the large tilt of Uranus (98°) is not from a collision, but instead had its natural tilt reinforced by a large moon that has since been ejected. Also, scientists tested the idea that the methane seen to change on Mars with the seasons might be from meteorites, and find that they don’t supply nearly enough to explain the observations. We also talk JREF, solar power, the Norway lights, and the usual nonsense. I just finished listening to the whole episode, and thought it was pretty good despite me being on it, so go give it a listen!
