Grateful Dead drummer Mickey Hart recently made some music out of astrophysical data about supernovas, short-lived stars in distant galaxies, in an attempt to "sonify" the universe.
One of the scientists who worked with Hart on the “Rhythms of the Universe,” project said that "What we did is turn it into sound by slowing down the frequency and ‘stretching’ it into an audio form. Both light and sound are all wave forms — just at different frequencies."
Here's a little video from the article with more interesting information.
