I'm finally up to date with astronomy cast. Took me a few weeks but now i'm current (caught up on the back catalogue

).
I enjoy it very much, thanks for the heads-up.
I've also just discovered a couple of new ones:
-
Keck Observatory Podcast Page which has some great podcasts featuring scientists who use the Keck Observatory.
-
Silicon Valley Astronomy Lectures. The only problem with this one, is that there's no RSS/XML feed so you have to download the files individually. I just finished listening to the one by
Dr Janice Voss, who has had a very interesting career as an astronaut on the space shuttle (5 times) and now a scientist on NASA's Kepler Mission, searching for extra-solar planets.
btw in-case you haven't seen it yet, there's a list of astronomy-related podcasts on IceInSpace under the Resources section -
Podcasts.
