The Sounds of Jupiter

One aspect of NASA's planetary research we haven't touched on is their space sound recordings. This video features "sounds" from Jupiter recorded by special instrumentation aboard Voyager. Electromagnetic vibrations from solar winds and charged particles in Jupiter's magnetosphere were collected and converted to sounds within the range of human hearing.

What do you think of Jupiter's song? Is it eerie or soothing? Or both, somehow? I find it to be an dense, alien language, created by ancient and ongoing processes that are shrouded in mystery and exist beyond the scope of human activity or influence. But let's give credit to the Voyager team, whose ingenuity brought us this strange, otherworldly song.

Spectacular Jupiter, largest planet in the solar system, is as mysterious as it is beautiful. Classified as a gas giant, all we can see of it are its cloudtops. These swirling, exotic clouds are made up of ammonia, hydrogen sulfide and water and are capable of generating lightning.

One of Jupiter's most distinctive features, the Great Red Spot, is a giant storm that has been raging since at least the 17th century, when it was first observed by humans.

Jupiter may have a rocky core; we don't know for sure. But most of its bulk comes from liquid metallic hydrogen - a form of hydrogen that only exists under extreme pressure.

Jupiter's rings were discovered during the Voyager 1 flyby in 1979. Apparently, two of the scientists on the Voyager team insisted that they look for rings, even though no one thought they would find any. And there they were. (The image below was taken by the Galileo spacecraft.)

I could go on with more facts about Jupiter, but let's face it - these planetary posts are really about the images. It can be hard to keep track of the news about the various spacecraft and each new set of dazzling images. By the time we finish with this tour of the solar system, you should be all caught up (at least for a little while!).
