NASA's Halloween playlist will 'make your skin crawl'

While it's true that humans aren't be able to hear sound in space, NASA scientists have converted radio emissions captured by its spacecrafts into sound waves - and the results are quite unsettling.

So plug in and listen to the sounds from our solar system, courtesy of Juno, the Van Allen Probes, Cassini, Galileo and Stardust and more. The playlist uploaded on Soundcloud includes a bunch of assorted sounds from the space agency's several missions over the year such as Jupiter, Saturn, and other celestial bodies.

The first, "Juno Crossing Jupiter's Bow Shock", is the sound of NASA's spacecraft moving across the gas giant's magnetic field.

Now it should be pointed out that these are not the sounds directly recorded from space.

Just in time for Halloween, NASA has released a compilation of spooky sounds comprising of radio emissions from howling planets and whistling helium.

"Juno's Waves instrument recorded the encounter with the bow shock over the course of about two hours on June 24, 2016", NASA officials said in the statement.

Another one comes from NASA's Van Allen Probes using the EMFISIS instrument which recorded the nearly rhythmic radio emissions that sound like the roaring ocean. This was captured on audio by the USA space agency. Saturn's radio emissions have also been made part of the compilation. Saturn is a source of intense radio emissions that are related to the planet's auroras near its poles.

In order to translate the radio signals captured at Ganymede, scientists used an approach called data sonification. This process became particularly useful when in 1996, the Galileo spacecraft passed by Jupiter's largest moon Ganymede.
