What does a supernova sound like?
Are these catastrophic explosions really as loud as they look?
Asked by Sophie Baxter
Sound itself can only be transmitted through a medium and so in space we cannot hear a supernova. However since a supernova is a giant explosion triggered by the final death throes of a massive star, if we could hear it, we would hear an incredibly loud blast.
Some scientists have gone a step further and actually tried to translate the huge amount of electromagnetic radiation produced by a supernova into sound. And what does a supernova sound like when you translate the high frequency electromagnetic radiation into lower frequency sound that humans can hear? Well, a lot like a big explosion really!
