Although space is a virtual vacuum, it does not mean there are no sounds in space. Sound does exist as electromagnetic vibrations.
Through specially designed instruments, the NASA Voyager used plasma wave antennas to record the vibrations all within the range of human hearing.
The recorded sounds are the complex interactions of charged electromagnetic particles from the solar wind, ionosphere, and planetary magnetosphere.
The recordings include: Saturn’s rings, Miranda, Neptune, Voice of Earth, Saturn, Jupiter, Rings of Uranus, and Songs of Earth.
The above video is a sample of the original recordings.
