The Planets have voices!

[SuperNova]

I think myself this is realy cool.
Jupiter kinda freaks me out cause it sounds singing ghosts. 

NASA - The Planets have voices....and they're CREEPY
Saturn Actual Sound
Sounds of Venus
Uranus - Space sounds
The Sound Of Pluto

I think myself this is awesome, they sound like they live.

Isn't it like... Radio waves they detect emitted from the planet and then converted to sound, cause light and sound are both waves.

I've always wanted to make a techno song with different sounds from space, like with a pulsar for a beat, and stuff.

Yes, they can't be actual sounds because, quite obviously, sound can't travel through a vacuum. However, it would be interesting what wave spectrum they analyse. Radio? Microwave? Gamma?

[atomic7732]

The planetary interiors aren't hot enough to emit gamma radiation.

Somewhere on Wikipedia I saw some chart where it was like:
1K - 10K = Microwave
10K - 100K = Radio
100K - 1000K = Infrared
1000K - 10000K = Visible
10000K - 100000K = Ultraviolet
100000K - 1 mil = X-ray
1 mil - 10 mil = gamma

It doesn't seem right though... I'm not sure, so don't trust me on this.

Here's a chart... http://upload.wikimedia.org/wikipedia/commons/thumb/c/cf/EM_Spectrum_Properties_edit.svg/675px-EM_Spectrum_Properties_edit.svg.png

There isn't any specific limits though.

Gamma rays can also be produced by radioactive decay. Also, microwaves are between radio and infrared.

My guess would be radio, though, but not for any particular or convincing reason.

As Bla said, gamma radiation can be produced by all kinds of things. There is definitely Bismuth on one of the planets of our solar system, for example, which emits gamma radiation.

The description from the Uranis video says:

"On the 24 January 1986, the probe Voyager 2 passes through the Uranus system.

The probe is carrying different detectors : magnetometers, plasma detectors, low-energy charged particles detectors, cosmic rays detectors, radiowaves receivers.

Recordings were made.

Interractions of the solar wind with planet's magnetosphere, magnetosphere itself, electromagnetic fields, charged particles emissions, charged particle interactions of the planet, its moons, and the solar wind.

All this electromagnetic phenomenons can be transformed into electric signals, which can in turn be amplified and used to excite the membrane of a loud speaker ; thus making audible to the human ear the rustling of the cosmos.


All these sounds were recorded while Voyager 2 was passing by Uranus, and assembled without manipulation.

From "Symphonies of the Planets vol.9 - Uranus" Nasa Voyager Recordings, Brain/Mind Research, 1990."

So the sounds are probably converted from several different sources, maybe even different ones from the different planets... It also makes sense to me since the sound from some of the planets seemed to change completely in structure sometimes (at least Saturn).

One scientific fauxpas...Uranus isn't a system.

(and neither is mine </badpun>)

No, but seriously.

[Bla]

Well it's not a star/solar system, but it could probably be called a system containing itself and the moons, rings and other objects orbiting it. Because a planetary system is just another word for a solar system, that'd be a bad word to use here, but the word would make perfect sense. The Sun is orbiting the center of our galaxy, and has planets with stuff orbiting them orbiting it. Uranus is in very similar situation, instead of planets it has moons, instead of asteroid belts it has rings, and instead of orbiting the center of the galaxy, it orbits The Sun.

It may not be used, but it'd make perfect sense to call it a system imo.

Gamma rays can also be produced by radioactive decay.

Due to the high energies at a small level... Otherwise, how else does the photon get so energetic?

Fred, I've got bismuth on my desk. lol It's like barely radioactive over the background radiation. (Bismuth-209 at least)

[atomic7732]

I can see how that's kind of contradictory. So nevermind.

Yes, I'm talking about the less stable isotops quite obviously
