New "Song" by (Not From) Planet Earth

DateFriday, September 14, 2012 at 8:50AM

WikipediaMy nerdy streak orbits through the world of astronomy and cosmology, so this sort of thing really appeals to me.

Boffins supervising the Radiation Belt Storm Probes' Electric and Magnetic Field Instrument Suite have recorded what they call "chorus."  Using instruments that monitor the Earth's magnetic field, they were able to capture audio radio waves emitted by the magnetosphere.

The "chorus" principle has been known for decades.  All planets with a magnetic field have them.  It's just that this recording is rather, well, tuneful.  

Listen to how Earth "sang" on September 5, 2012 here.

I want to hear the new version in a few years, when Planet X passes close to Earth slightly tilting it's axis
