"Music" Of the Sun Recorded By Astronomers 94

Posted by samzenpus from the good-day-sunshine dept.
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.'"

      Or with the newer version:

      Not quite as catchy a tune as the first one, but still a good song.

      • 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.

        So they didn't actually record it, they just recreated it. Which means there is a possibility they are wrong. In which case they may have the right tune but the wrong lyrics or vice versa.

In pretty much the same spirit of color processing/enhancement, it 'normalizes' the emissions into a hearing range- this can give one tools to perform more intuitive science, something that always encapsulates a potential for further discoveries- why not 'see' in UV or IR or whatever, since we do have the means to do so?

    Dr. Fiorella Terenzi, an itialian astrophysicist, has captured radio waves from a distant galaxy 180 million light years from Earth, converted cosmic waves into sound and transformed the sound into music.

    You may never have heard anything like Dr. Fiorella Terenzi's music, but you may recognize the musicians on her 1991 album, Music From the Galaxies. On lead vocals: Jupiter! ("It whistles," she says.) On rhythm guitar: the Sun! ("It bubbles like boiling water.") On drums: pulsars! ("A precise beating time") On bass: Mother Earth! ("It has a very low frequency.") Astrophysicist Terenzi assembled her cosmic combo while studying at UC-San Diego. Using radio telescopes and computer sound-synthesis technology, she intercepted space signals and transformed them into tunes.
