I was seraching for random videos on YouTube and this video came up

Then I also found these two videos

According to the videos' descriptions' these sounds were recorded by Voyager during it's travels.

I think these sounda are reeeally creepy! What are your thoughts? Have you got a similar video to post?Please discuss :) .

Warning: Saturn might scare you a little bit. I kept saying to myslef"No scary picture will pop up, no scary picture will popo up..." :p .

They pretty cool, but sound more like them ambient sounds or music.
Earth has a cooler one :p

Planets don't talk unless you have the Password.

You've been had.

Indeed, some of them would be cool as a Tomb ambience in a future Tomb Raider game :p .

Listening to the Saturn one now. That really is creepy. CD should put noises like this in a dark and dingy tomb.

The Earth one sounds like a car racetrack.

Jupiter and Saturn sound magnificent.

It's the middle of the night and I've just heard the Saturn one.

...Might not sleep. :pi:

Thanks for sharing. :tmb:

There is no sound in vacuum, those are fakes. Good ambient though.

It's each planets "electromagnetic signature" which is then turned into sound.

Aurora borealis also makes a sound. Very eerie!

Good luck trying :D .

As interstellardave these "sounds" are electromagnetic emissions which, thanks to the special equipment Voyager was equipped with, was turned into sounds :) .

Sounds intresting, do you have a video to post :) ?

Wow, that is so interesting!! I love it! I wish we could here the inner planets, but I guess voyager never went by them. :p

Saturn is disturbing. These are interesting sounds, the universe is a fantastic place.

I suspected it would be something like that, although I have to say I did think they were just youtube fakes at first. Admittedly I know very little about sound processing but I suspect you need to take a lot of liberties to arrive at something as elaborate and approriately moody as the first video (and then sell it as a CD (http://www.amazon.com/Symphonies-Planets-NASA-Voyager-Recordings/dp/B000001V2O) :pi: if I'm thinking right and that's the source of the vid).

I had a quick further look but I can't find the method used for those particular recordings. The existing radio wave recordings from the Voyager (the ones that I'm aware of) don't even come close in complexity to the vids in the original post.

Oh the 12-year-old within me just giggled at "Uranus sounds".
Anyway, it's really interesting.

I didn't read the whole page yet, but this site explains what went into making these recordings:

Quite interesting. Thanks for sharing!

I wondered how it was possible to record sounds from space.

I wondered how it was possible to record sounds from space.

A majority of information about planets obtained by space probes comes from electromagnetic data, such as radio waves, but most of it is still of frequency outside of human hearing. The simplest way (I think) to make it work is to crank up the wavelength of the radiation up to the audible range, and maybe compress the length of the recording because otherwise it could be quite boring (don't think anyone would care to spend a million years listening to a Big Bang simulation :p ). So yeah, you can convert data points into a sound and then put several of them together but I tend to hesitate when it comes to calling the effect such grandiose names as "the sound of Jupiter". Maybe I'm kneejerking though :p

EDIT: OK found this (http://www-pw.physics.uiowa.edu/space-audio/cassini/SKR1/) which is radio emission of Saturn's polar auroras and appears in the second vid. Bit of a jumping the gun accusing the vids of being fake :o
