The sun also sings.

Music of the sun recorded by scientists

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.

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.
He said: “These loops are oscillating like the strings on a guitar or the air in a wind instrument. Over time the waves die away and that is telling us new things about the physics in the sun’s atmosphere.”
