    Sounds from Space

    https://www.youtube.com/watch?v=e3fqE01YYWs

    That link is to a video with so called sounds from Jupiter. I know sound waves can't propagate in space and that electromagnetic radiation like radio and microwaves are the only recordable sounds. What is the audio in that video based on? It doesn't sound like the usual clicks and chirps of radio waves, but eerie synthetic music.

    Also, what would you hear if it were possible to place a microphone inside the sun, or on it's surface if you could fashion some kind of magic mic that wouldn't be destroyed?

    Sounds completely orchestrated and synthsised to me.
    here's NASA's own recordings: http://www.nasa.gov/vision/universe/...en_sounds.html
    and
    https://solarsystem.nasa.gov/galileo/sounds.cfm

    Nothing like that YouTube, is it?

    any electromagnetic wave could be translated to sound. You would probably want to shift the wavelengths involved to actually hear anything but we shift wavelengths all the time to "see" light we normally can't see. With sound you might just increase slow the whole thing down which would lower the pitch and lengthen the recording. You could lower the pitch but keep the timing but that requires you to remove information from the translation.

    If you could put a microphone into the sun and record real sound all you would here is a deafening static. The ions hitting the microphone would be pretty much random and very high in energy (=loud)

    on a side note you could translate pretty much anything to sound. Textures are easy. We do that with records. Taste and smells could also be translated in the same manor if you had proper detectors.

    What does the surface of Venus sound like?

    Probably just like the wind blowing but just a little deeper. No crickets, traffic, or birds to get in the way.
    At least that's what I infer from this example of Earth vs Titan vs Mars vs Venus.
    And this one with a longer video, but a lot more ads.
