NASA revealed that the odd space sounds were captured as radiowaves, which have now been converted into sound waves of "howling planets" and whispering noises from distant stars.
"Soaring to the depths of our universe, gallant spacecraft roam the cosmos, snapping images of celestial wonders".
In time for Halloween, NASA has put together a compilation of elusive "sounds" of howling planets and whistling helium that will make your skin crawl.
House passes $4T budget in step forward for Trump tax plan
The head of the House tax-writing panel isn't ruling out changes to the 401 (k) retirement program to raise revenue for tax cuts. The longer tax reform languishes on Capitol Hill, the more time K Street will have to nitpick this legislation to death.
The key ones include the one that came from Juno when it crossed the boundary of Jupiter's magnetic field. Juno's Waves instrument recorded the encounter with the bow shock over the course of about two hours on June 24, 2016.
Saturn appeared to also produce a spooky version of Star Trek-like sound effects thanks to its source of intense radio emissions.
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.
NASA said that the data used to create the playlist was collected by instruments on spacecraft that capture radio emissions, which scientists converted into sound waves.
This clever hack is called data sonification, and it helps researchers "hear" what's going on with their far-flung spacecraft around planets, moons, comets, and other locations. NASA's Stardust spacecraft was bombarded with dust particles from the comet, and this is what can be heard in the recording.
