NASA Space Sounds: what happens when spacecraft are used to record radio emissions from planetary environments, which are then converted to sound waves.
Some spacecraft have instruments capable of capturing radio emissions. What you’re hearing is the result of scientists’ conversion of these radio emissions to sound waves. Instruments on NASA’s Voyager, INJUN 1, ISEE 1 and HAWKEYE space probes were used to record the vibrations of different objects in our solar system.
The recorded sounds are the complex interactions of charged electromagnetic particles from the solar wind, ionisphere, and planetary magnetosphere.
The space sounds are really amazing! Nothing was added or tweaked either, these are the beautiful sounds which emanate from that mysterious world above and beyond. Enjoy!
