Science is just mind-blowing sometimes.

Remember last week when we made history by landing on a comet?

Well, that comet has a weak magnetic field that appears to be oscillating at low frequencies. To put that into terms that all of us normal human beings can understand, it's making an eerie sound.

You've got to hear this to believe it.

Scientists don't yet fully understand what's making the comet sing like this, but it's just another example of how much there still is to learn about these fascinating celestial objects.
