Okay, I'll admit it. Deep in my secret heart, I'm a 12 year old, and couldn't pass up the opportunity for this truly tremendous, and disgusting pun.
Now that that's out of the way, seriously, this thing is amazing. What I'm talking about is a series of "recordings" made by NASA of electromagnetic radiation caused by celestial bodies in outer space. They transform the wave patterns into sound (much like an AM or FM radio does to radio waves here on earth). Thanks to my friend Shokolada for pointing that out, by the way.
The results are haunting and beautiful.
