Om (also written as Aum or Ohm) is an ancient mantra and mystical sound of Hindu origin (India and Nepal). The second video below is a report on these findings. Both of them were excited by bursts of solar activity, and according to space physicist Don Gurnett, the principal investigator for the Plasma Wave Science instrument on Voyager 1, space can make music if you know how to listen. In a news report released in late 2013, NASA published that Voyager 1 (another space probe to study the outer Solar System) has recorded two outbursts of “interstellar plasma music” - one in Oct-Nov. To study this and understand the power of the sun, the Faculty of Science at University of Sheffield also launched a project called ‘ Project Sunshine‘.
Professor Fáy-Siebenbürgen explained that studying the “music of the sun” can provide new ways of understanding and predicting solar flares before they happen. The motive of the investigation was to study the growing concerns about the increasing solar activity that can have catastrophic effects on earth. Note that the video actually shows eruptions from the solar corona, embedded with the recreated audio. You can see the same in the short video from a NASA space telescope TRACE (Transitional Region and Coronal Explorer) designed to study and investigate the magnetic fields and the associated plasma structures on the Sun’s atmosphere. The noise from such a large and powerful source as Sun sounded as a sort of music because it has harmonics.
So the scientists at the University of Sheffield used the satellite images of giant magnetic loops spread over thousands of miles to recreate the sound - by turning the visible vibrations into noises and speeding up their frequencies to make them audible to the human ear. Since sound cannot travel through the near vacuum of space, scientists cannot record the sounds produced in the Sun’s atmosphere directly.
