The Song of the Sun – just like its 11-year & 22-year cycles – is governed by its magnetism.
The You Tube video embedded here is from V101 Space. (It comes complete with sub-titles in Tagalog for my friends in the Philippines!)
To hear an audio version of the “hum” of the Sun, try this link from Stanford University: http://soi.stanford.edu/results/sounds.html (Choose the format according to whatever program you have on your PC. Mine plays the AU but not the AIFF format, for example).
The Sun is a magnetic ball composed largely of plasma, with a solid core surrounded by liquid moving in waves. Recent photographs taken by solar observatory spacecraft show us a lot about the visible surface, although mainstream science is reluctant to accept what it sees. If you find yourself interested in the Sun, explore some of the its sounds that can be found on the internet, via Google.
