Jim Bumgardner has created a lovely sound project that brings to life the music of the spheres: "Wheel of Stars."
I downloaded public data from Hipparcos, a satellite launched by the European Space Agency in 1989 that accurately measured over a hundred thousand stars.Sean Bonner, upon whose blog I discovered this, says, "I highly recommend fullscreen and the use of headphones. Listening to this is hypnotic. I want it to play constantly in the background of my life."
The data I downloaded contains position, parallax, magnitude, and color information, among other things.
