Twinkle, twinkle, little star. How I wonder what you, wait a minute, why are you twinkling so much? Um, guys, that's no diamond in the sky. That looks like a supernova. As much as we love to blow stuff up here on Earth, no bombs or pyrotechnics could compare to the incredible force of nature's biggest explosion, the supernova. As a star reaches its grand finale and explodes, what would happen to life on Earth if we were close by? How far away from a supernova are we considered safe? Could anything survive its deadly radiation? What makes supernovae valuable to us?
