Astronomy Cast Ep. 437: Destroy and Rebuilt Pt. 1: The Torino Scale

https://www.youtube.com/watch?v=cWrhMZiONSw Streamed live on Jan 27, 2017. We love to destroy the Universe, and also rebuild it. Today we begin a new series where we destroy and rebuild. Let's talk about some existential threats we face and ways we could recover, starting with the Sword of Damocles hanging over our heads: killer asteroids. http://neo.jpl.nasa.gov/risk/ "Dr. Gay, or How to learn to stop worrying and love the asteroid."
