Episode 5 goes live May 19, and Josh and Addie welcome Walkabout-er Tracy Becker for a discussion of the LADEE mission which recently expired by crashing onto the Moon. Josh describes getting lost at the European Geosciences Union meeting in Vienna and likens it to getting sliced into tiny pieces. Here’s a link to the movie Cube discussed before getting around to lunar science. Also hear Josh confuse Colorado with Central Florida. So embarrassing!
Addie and Josh discuss two of Saturn’s 60-plus moons, and one of them may not even be a moon. Yet. Intrigued? Check out Episode 4, available now, to hear about the discovery of the subsurface water lake on the moon Enceladus and a baby moon named “Peggy”. Because what is more awesome than a baby moon named Peggy?
In Episode 3, now available on iTunes, we welcome Professor Tom Statler (University of Ohio and University of Maryland) who tells the fascinating story of how sunlight can make an asteroid literally fly apart, and one was caught in the act by the Hubble Space Telescope. The process is called YORP, and yes, it does have to do with the Muppets. Also we ponder the amazing case of an outer-solar-system asteroid (a “Centaur”) that apparently has two narrow rings circling it.
Episodes 3 and 4 are in the bag (or the solid state drive on my computer, to be exact). Episode 3 features special expert guest Professor Tom Statler, Visiting Professor of Astronomy at University of Maryland and Professor of Physics and Astronomy at Ohio University, who discusses recent discoveries of asteroids broken apart by sunlight and the intriguing discovery of rings around a Centaur (an asteroid or comet-like thing-y in the outer solar system, between Jupiter and Neptune) with Josh and Addie. I’m working on improving the audio quality as well. Episode 5 will feature a special twist. If there’s a topic you’d like to hear about, let us know in the comments here or on our facebook page.
New statistical analyses of data from the Kepler planet-finding spacecraft added over 700 exoplanets to its already impressive total. In this, our first episode, Josh interrupts Addie and Ashley much more often then they interrupt him.
Walkabout the Galaxy is a podcast hosted by Joshua Colwell, Addie Dove, and Ashley Kehoe. We choose a recent development from the world of astronomy and, with any luck, get to actually discussing it before the end of the podcast. Beware of the occasional infantile joke mixed in with our sincere efforts to not make too many mistakes when discussing matters outside our areas of expertise.
