Damm.
I knew some of the AAS presentations had been podcast, I just couldn't find the link...
Finally:
AAS podcasts - right now it is a dozen or so from the 2007 Jan meeting in Seattle.
I liked Brown's talk on hypervelocity stars.
I missed Brown's talk on Kuiper belt objects, but heard good things about it.
Julianne from CosmicVariance is also there, as is the COSMOS press conference.
Haven't browsed the archive, probably full of good stuff.
