But now one part of it is audible.
Music from the sun.
Astronomers at the University of Sheffield in the UK have for the first time recorded “eerie musical harmonies produced by the magnetic field in the outer atmosphere of the sun”, says the Telegraph.
Huge magnetic loops observed “coiling away from the outer layer of the sun’s atmosphere, known as coronal loops, vibrate like strings on a musical instrument”, says the story.
“In other cases they behave more like soundwaves as they travel through a wind instrument”, says the story, continuing >>>
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.
“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.”
How cool is that?
“The coronal loops are thought to be involved in the production of solar flares that fling highly charged particles out into space, creating a phenomenon known as space weather” the Telegraph says, adding.
“Nasa warned last week that the sun’s activity is starting to increase following an extended period of low activity and is on course to throw out unprecedented levels of magnetic energy into the solar system by 2013.”
