O que é que tem nove quilómetros e meio e pode acabar com a civilização num segundo? Um asteroide — e há muitos deles por aí. Com humor e excelentes imagens, Phil Plait cativa o público da TEDxBoulder ao explicar todas as maneiras como os asteroides podem matar, e o que temos de fazer para os evitar.

Phil Plait blogs at Bad Astronomy, where he deconstructs misconceptions and explores the wonder of the universe. Full bio
