What Sound Does Space Make?

Ever wonder what a blackhole sounds like? The sun? Remnants of the Big Bang? Yeah, neither had we but it turns out the answer is wind crossed with radio waves, an electronic heartbeat and the ocean. How? SpaceSounds has collected a handful of radio telescope recordings of pulsars, planets and machines (check out the oddly-addictive beeps of Sputnik). There are also human voices in the mix: Kennedy gives his "Man on the Moon" speech, ground control and the Apollo spacecraft communicate, a ground operator highlights technical issues Skylab 1 experiences during liftoff.
