What's six miles wide and can end civilization in an instant? An
asteroid - and there are lots of them out there. With humor and great
visuals, Phil Plait enthralls the TEDxBoulder audience with all the ways
asteroids can kill, and what we must do to avoid them. Phil Plait currently blogs for Bad Astronomy, a Discover Magazine Blog, he worked for six years on the Hubble Space Telescope, and directed
public outreach for the Fermi Gamma-ray Space Telescope. He is a past
president of the James Randi Educational Foundation, and was the host of
Phil Plait's Bad Universe, a documentary series on the Discovery
Channel.
