NASA Spooky Space 'Sounds' Serve Up Intergalactic Treat for Halloween

NASA Space

"In regions laced with magnetic fields, such as the space environment surrounding our planets, particles are continually tossed to and from by the motion of various electromagnetic waves known as plasma waves", NASA said, earlier this year. Maybe it's time to spice it up with some truly scary tracks: horrifying sounds from the void of space.

The key ones include the one that came from Juno when it crossed the boundary of Jupiter's magnetic field.

The scientists at NASA want to get us all in the Halloween mood with a playlist of spooky sounds collected from the agency's interstellar missions.

Scientists sometimes convert radio signals into sounds in order to understand them better. A clipping tagged as "Crossing Jupiter's Bow Shock" comes from Juno's Waves instrument, which recorded the encounter with the bow shock over the course of 2 hours on 24 June 2016. An audio picked by the spacecraft shows data from Galileo's Plasma Wave Experiment instrument. Saturn's radio emissions have also been made part of the compilation. The radio waves are closely related to the auroras near the poles of the planet.

From the eerie crackling sound of a comet encounter captured by the Stardust spacecraft to the rhythemic sound of plasma waves captured by the Van Allen Probes, some of the audio clips might as well have been sound effects from a horror movie. The sounds recorded are very similar to the radio emissions from Earth's auroras.

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.

Be sure to have this playlist handy when trick-or-treaters pay you a visit this Halloween.
