25 Jun 10 - 11:08 AM (#2934620) Subject: Music Of The Sun Recorded By Scientists From: bobad Astronomers at the University of Sheffield have managed to record for the first time the eerie musical harmonies produced by the magnetic field in the outer atmosphere of the sun. They found that huge magnetic loops that have been observed coiling away from the outer layer of the sun's atmosphere, known as coronal loops, vibrate like strings on a musical instrument. In other cases they behave more like soundwaves as they travel through a wind instrument. Using satellite images of these loops, which can be over 60,000 miles long, the scientists were able to recreate the sound by turning the visible vibrations into noises and speeding up the frequency so it is audible to the human ear. Professor Robertus von Fáy-Siebenbürgen, head of the solar physics research group at Sheffield University, said: "It was strangely beautiful and exciting to hear these noises for the first time from such a large and powerful source. "It is a sort of music as it has harmonics. http://www.telegraph.co.uk/science/space/7840201/Music-of-the-sun-recorded-by-scientists.html |
