Space Sounds

I've found a new trick to relieve my occasional bouts of insomnia. Whenever the sandman is being a jerk and refusing to come visit me, I put on this recording of Jupiter's moon Io. Something about it is so soothing, it's like a galactic lullaby. I won't attempt explain to you the science behind how NASA was able to capture the sounds of planets and moons (I barely understand it), but I would like to tell you about the myth of Io and share my favourite painting of the subject.
