Did astrophysicist Neil deGrasse Tyson really kill the planet Pluto? Not exactly, although he admits he did "drive the getaway car." He was a teenager when some insisted that comet was going to destroy the world. He disagreed - it would simply be a great chance to take some cool photos - and he was right. When DC Comics needed someone to find Superman's home planet, they called him. See why people turn to Tyson, one of the world's most famous scientists, for his thoughts on the universe.
