I found this site in a strange way. I plugged in my iPod, went to the iTunes store, and noticed a banner for "a collection of podcasts from outer space." Clicking this revealed a page with 15 space and astronomy-related podcasts and video podcasts. Several are from NASA and I was familiar with a few others including the excellent Astronomy Cast. I downloaded some samples to check out (podcasts are most often free).
One of the new ones (for me) is the video podcast SPACEGEEK VIDEO, so I checked out a few of these brief episodes on subjects ranging from Celtic astronomy to the expansion of the universe. They are produced and hosted by zany astrophysicist "doctor-P" (how often do you see the words "zany" and "astrophysicist" in the same sentence? - his real name is Dr. Jean-Marc Perelmuter). You can find Doctor-P's videos on his web site (Flash format) as well as in the podcast section of iTunes for free download. Doctor-P does a nice job on these amusing space and astronomy mini-lessons - and unlike my blog, you can even view them in China!
