Phil Plait on Asteroids
A few weeks ago, astronomy was back in the news after a meteor exploded over Russia, injuring scores of people, the same weekend that an asteroid narrowly missed the Earth. Phil Plait writes about these kinds of phenomenon for his Slate blog, Bad Astronomy. He says that, while we should be worried about extraterrestrial threats, in the end, there's only so much that we can prepare. Phil Plait is speaking at the University of Illinois on Friday, March 8th.
