Two fun audio/visual links for you today, both brought to you by APOD, which I've mentioned before.

First, a galactically packed image where each galaxy has a sound based on its distance:

The Hubble Ultra-Deep Field in Light and Sound

Next, a cross-section of Saturn's rings, which can be played in both major and minor keys.

Play Saturn's Rings Like a Harp

Safe travels (mind the tribbles and the treble clef) as you enjoy you voyage through space and sound!
