Sun song
Scientists at Sheffield University in the U.K. have just released what amounts to a recording of what you would hear if you could stand inside the solar corona — the upper layer of the sun's atmosphere — and it turns out that what you'd hear is music.
The corona is filled with vaguely banana-shaped plasma structures known as coronal loops, which vibrate side to side like a guitar string and stretch and contract along their lengths, which is what happens to air when you blow into a wind instrument.
The university team used a computer algorithm to convert visual data to acoustical information and sped up the frequency of the sound so it would fall within the human auditory range. They've posted a six-second recording of the results that sound like a cross between the final chord from the Beatles' "A Day in the Life" and whale song.
Solar ringtone, anyone?

Cool :). They sound very errie. I just had a thought. Those loops must be the solar systems largest tuning fork :), although they are not very well tuned since they have harmonics :)
