Forget creaking hinges and nearby footsteps. For some real Halloween chills, check out NASA’s new playlist of spooky signals picked up by its spacecraft over the years.
“Soaring to the depths of our universe, gallant spacecraft roam the cosmos, snapping images of celestial wonders,” the space agency said. “Some spacecraft have instruments capable of capturing radio emissions. When scientists convert these to sound waves, the results are eerie to hear.”
Even the names of the tracks are mysterious. There’s “Radar Echoes From Titan’s Surface,” a pulsing rhythm suddenly interrupted by some electronic blips followed by an ominous revving sound. “Plasmaspheric Hiss” almost sounds like breathing. And the whistling “Plasmawaves – Chorus” resembles a distant call.
Of course, none of these sounds were caused by space ghosts (or even Space Ghost). Each had a more down-to-earth explanation, which NASA posted on its website. For example, plasma waves “like the roaring ocean surf, create a rhythmic cacophony that ― with the EMFISIS instrument aboard NASA’s Van Allen Probes ― we can hear across space.”
