Scientists at the University of Sheffield have recorded the "music" produced by the magnetic field in the outer atmosphere of the sun. They discovered that the huge magnetic loops that coil away from the outer layer of the sun's atmosphere, known as coronal loops, vibrate like strings on a musical instrument or behave like soundwaves traveling through a wind instrument. From the article: "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. It is providing us with a new way of learning about the sun and giving us a new insight into the physics that goes on at in the sun's outer layers where temperatures reach millions of degrees.'"
