<<Fifteen thousand years ago, North America was like the Serengeti on steroids, with mega-creatures roaming a continent teeming with incredible wildlife. But then, in a blip of geologic time, between 15 and 35 magnificent large types of animals went extinct. In this television exclusive, NOVA joins forces with prominent scientists to test a startling hypothesis that may finally explain these sudden and widespread extinctions
that a comet broke apart in the atmosphere and devastated North America 12,900 years ago.>>

Viewing Alert: Hunting The Edge of Space
The PBS series "Nova" has produced a two-part special in honor of two remarkable anniversaries: the 20th anniversary of the launch of the most famous telescope in history, the Hubble Space Telescope, and the 400th anniversary of the publication of Galileo’s “Starry Messenger,” a book that started a revolution in our understanding of our place in the cosmos. Part 1 aired April 6, 2010 and if you're like me and you missed it, you'll be happy to know it is now available to watch online. Part 2 will air on April 13, 2010 and likely will be available online a few days later. You can watch a preview to whet your whistle
