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, ionosphere, 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.

The Cassini spacecraft has been detecting intense radio emissions from the planet Saturn. They come from the planet's aurorae, where magnetic field lines thread the polar regions. These signals have been shifted into the range of human hearing and compressed in time:

On the 24 January 1986, the probe Voyager 2 passes through the Uranus system. The probe is carrying different detectors : magnetometers, plasma detectors, low-energy charged particles detectors, cosmic rays detectors, radiowaves receivers. Recordings were made. Interractions of the solar wind with planet's magnetosphere, magnetosphere itself, electromagnetic fields, charged particles emissions, charged particle interactions of the planet, its moons, and the solar wind. All this electromagnetic phenomenons can be transformed into electric signals, which can in turn be amplified and used to excite the membrane of a loud speaker ; thus making audible to the human ear the rustling of the cosmos. All these sounds were recorded while Voyager 2 was passing near Uranus' moon Miranda, and assembled without manipulation:

Neptune is the outermost planet of the gas giants. It has an equatorial diameter of 49,500 kilometers (30,760 miles). If Neptune were hollow, it could contain nearly 60 Earths. Neptune orbits the Sun every 165 years. It has eight moons, six of which were found by Voyager. A day on Neptune is 16 hours and 6.7 minutes. Neptune was discovered on September 23, 1846 by Johann Gottfried Galle, of the Berlin Observatory, and Louis d'Arrest, an astronomy student, through mathematical predictions made by Urbain Jean Joseph Le Verrier:

Astronomical bodies emit radio waves which can be captured by the specially designed instrument known as 'astronomical interferometer'. This device can extract sound from the radio waves within the range of human hearing (20-20,000 Hz). Voyager and Hawk-eye are among many probes which record space sounds:

The Voyager program was a series of United States unmanned space missions consisting of a pair of unmanned scientific probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable planetary alignment of the late 1970s. Although they were officially designated to study just Jupiter and Saturn, the two probes were able to continue their mission into the outer solar system. The Voyager spacecrafts each had equipment capable of recording emission signals given off by the planets, their moons and their ring systems. These pieces of equipment are designated as planetary radio astronomy investigation instruments (PRA) and are used in radio astronomy. Recordings were made capturing interactions of the solar wind with the planet's magnetosphere, magnetosphere itself, electromagnetic fields, charged particles emissions, charged particle interactions of the planet, its moons, and the solar wind. All this electromagnetic phenomenons can be transformed into electric signals, which can in turn be amplified and used to excite the membrane of a loud speaker ; thus making audible to the human ear the rustling of the cosmos. All these sounds were recorded while the Voyagers were passing near their targets, and assembled without manipulation, using Audacity:
