Earth’s Magnetic Field Vibrates Like a Drum

Earth’s Magnetic Field Vibrates Like a Drum

Using data from NASA’s THEMIS mission, scientists have discovered ¬that when the Earth’s magnetopause is struck by a jet of plasma from the Sun, it vibrates like a drum, with waves echoing back and forth along its surface, much like they do on top of a drumhead. The new discovery comes several decades after such behavior was first theorized.
