Well actually, it is not a sound as such. But as you probably know, sound itself is a vibration, and the stars vibrate. Those star vibrations were
detected and recorded, and the resulting vibe as been shift a few octaves to the high, to render that vibration audible. On its original frequency, it
is what is called infrasound, as opposed to ultrasound, which vibrates too high to be audible.
I believe that cdrkeenkid could give you more details on what the vibration of the star is as such, but I believe it is actually the light pulse
variations of the star that are recorded. Light also is a "vibration" (it is a wave, but I should maybe have called vibration "waves" before, it
is basically not different), and the difference in the light intensity and color are measured. Those color differences are actually a difference of
It is a very small difference. According to the MOST site where that recording comes from, it is about equivalent to the difference you would notice
when the distance between your eye and a light source situated 1 km away, would vary of 0.5mm!
Hope it helps...
