It’s Good to Know: The Sound of the Aurora Borealis

The aurora borealis (also known as the northern lights) is a phenomenon that produces a spectacular light show in the Earth’s northern polar regions. And the greenish glow, the result of microscopic particles colliding in the atmosphere, is sometimes accompanied by noise. Those who have heard it say it sounds like radio static or a crinkling cellophane wrapper.

The cause of the noise is not known, and it has never been recorded. According to Inuit folklore, it is the sound of dead spirits.
