Extrasolar Planets and IR Astronomy

I don't want to wear out this YouTube video thing, but the scope of what's out there is really amazing, and not just for funny stuff. The brief (4:42) video shown here was created by the Spitzer Science Center at Caltech and is part of a video clip series available at their own web site, though it seems to require a download there, while the YouTube version starts playing immediately. This of course is part of the appeal of YouTube - immediate video gratification, whether you seek clips of Borat or explanations of infrared astronomy used to observe temperature differences on the surface of an extrasolar planet as in this case.

P.S. The Spitzer IR telescope is not as well known as the Hubble, but it has produced some equally stunning images. Check out this gallery of zoomable images.
