TV Alert! Tonight, the Discovery Channel is airing a show called "Cosmic Collisions", about, well, things that go smack in the night. Asteroid impacts, galaxies colliding, gamma-ray bursts... this three-part series should be of interest to anyone who read my book and wondered what this stuff looks like. DC has more info here, and Dave Mosher has more on his Space Disco Blog. Check your local listings for times.
