Nice.
I heard a CD is available with all the tones. But I'd just torrent it

Yes, very nice, I remember of it, thanks for sharing.

PIA07967 -Bizarre Sounds of Saturn's Radio Emissions(Article from NASA website)

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 Saturn's radio emissions.



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 instrument has now provided the first high resolution observations of these emissions, showing that show an amazing array of variations in frequency and time. In this example, it appears as though the three rising tones are launched from the more slowly varying narrowband emission near the bottom of this display. If this is the case, it represents a very complicated interaction between waves in Saturn's radio source region, but one which has also been observed at Earth.

Time on this recording has been compressed such that 13 seconds corresponds to 27 seconds. Since the frequencies of these emissions are well above the audio frequency range, we have shifted them downward by a factor of 260.

That's cool
Them tones would send me to sleep

I suppose it's better than hearing it come from uranus!!

fuck music on saturn sucks ass!

[Guderian1974]

That is some cool shit....234 [B]MILLION[B]miles! Can you imagine?!?!?

It must be voices from the past..I think saturn is like a satellite that filters sounds and voices from other far away galaxies.

I'd liked them more when they were still underground.

how can sound travel thru space.. i thought sound waves are longitudinal waves.. (need medium) to propogate..??
this thing is out f ma mind
