You may recall that I've mentioned my colleague Mark Devlin, his work on the Balloon-borne Large-Aperture Submillimeter Telescope (BLAST) experiment, and the thrilling movie about it that his brother Paul put together. Well, this evening cosmology will get some welcome exposure when Mark will be the guest on The Colbert Report, airing, as usual, at 11:30pm EST on Comedy Central. A few friends of the blog have appeared on the show before, and it can be a real challenge to get any information across at all while Colbert is doing his thing (this is a comedy show, after all). But if you can manage it, you've got a much bigger audience than we're used to. So good luck Mark!
