Music of the sun recorded by scientists

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 sound waves 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.

  “The sun has been the inspiration for hundreds of songs, but now scientists have discovered that the star at the centre of our solar system produces its own music.”
