Sixty five million years ago, scientists say, an asteroid the size of a small city obliterated the dinosaurs. Are more killer asteroids on their way? Scientists around the world are scanning the heavens for dangerous Earth-bound objects, but the question remains — if they find them, can they be stopped?
