Space Sounds

When I was a child, we got a free 45 RPM record of space sounds with the Time-Life book "The Universe" which my parents purchased for me for my birthday.
It was upon the first playing of this record that I became fascinated with space sounds.
I would listen to the record over and over, as the velvety-voiced narrator talked about things like Kepler's Harmonices Mundi. On the B side, you could listen to beautiful actual space sounds.

In my teen years, I discovered Pink Floyd's Dark Side of the Moon. DSOTM was not nearly on the same level as actual space sounds, but when you're a teenager, playing actual space sounds in the tape deck would be a good way to earn the "Geekiest Girl" superlative for the yearbook.

I thought I'd share some of my favorite space sounds with you.
Here is one I love so much it's on my profile on this site.
It comes to us courtesy of the Cassini-Huygens space probe.
With probes like Cassie, we continue to collect more and more amazing space sounds.

Have a listen:

Here is NASA's explanation of the sounds:

Saturn is a source of intense radio emissions, which have been monitored by the Cassini spacecraft. The radio waves are closely related to the auroras near the poles of the planet. These auroras are similar to Earth's northern and southern lights. This is an audio file of radio emissions from Saturn.
The Cassini spacecraft began detecting these radio emissions in April 2002, when Cassini was 374 million kilometers (234 million miles) from the planet, using the Cassini radio and plasma wave science instrument. The radio and plasma wave instrument has now provided the first high resolution observations of these emissions, showing an amazing array of variations in frequency and time. The complex radio spectrum with rising and falling tones, is very similar to Earth's auroral radio emissions. These structures indicate that there are numerous small radio sources moving along magnetic field lines threading the auroral region.
