While reading an article in Discover magazine about the Earth's hiss - one of the top science stories of 2008, this image kept popping into my head. This is the resulting doodle.
The Earth's hiss is a "mysterious electromagnetic wave surrounding the earth that, when played through a loudspeaker, sounds like hissing and swishing between tracks on a scratchy vinyl record." It was formerly known as "the chorus." Fascinating! (It's really just a giant alien snake monitoring the earth, hence the hissing)
