There isn’t supposed to be any sound in space. Without a medium, sound has no way to travel. The vacuum of space is silent.
Or is it?
It’s not, actually. While it’s true that you can’t hear things in space as you would, say, on Earth, sound does travel as electromagnetic waves. As it turns out, space is a very noisy–and rather musical –place.
Jupiter, the rings of Saturn, even the Earth all “sing,” in a way. And for more than 40 years, NASA has hidden the fact that Apollo astronauts heard “space music” of some sort through their headphones when they passed around the far side of the moon.
So the moon “sings,” too—but no one knows why. There’s no magnetic field and no atmosphere. Alien bases? The singing moon is going to generate a lot of research interest.
