Getting into the Halloween mood, NASA has released a compilation of the sounds of space which are the emissions from the electromagnetic spectrum. This brings to life the radio emissions capture by its spacecraft goes across the solar system. The collection includes the roaring marble of lightning on Jupiter to the eerie boom of starlight. The sounds are now shared in a new playlist on Soundcloud is made available on YouTube. Scientists converted the radio emissions which were collected across the various missions into sound waves to make the sounds available for public listening. And ahead of Halloween, the space agency has released ‘Spooky Sounds from Across the Solar System’ playlist which includes 22 snippets of space sounds.
The sounds are a fresh look into the mysterious objects in our solar system. The list also includes a clip where the Juno spacecraft crossed the boundary of Jupiter’s magnetic field on June 24, 2016, and its encounter with bow shock over two hours. The playlist also contains examples of Saturn’s radio emissions gathered by Cassini spacecraft. Scientists used the craft’s sensors to measure the amount of dust in the area on April 26 and converted the data measuring each dust particle that collided with the sensor – into sound. The sound includes noises of crackles, whorls, and snarls that sounds.
Cassini Crossing Saturn’s Planet-Ring Gap on April 26, 2017:
Juno Captures the ‘Roar’ of Jupiter: NASA’s Juno spacecraft has crossed the boundary of Jupiter’s immense magnetic field. Juno’s Waves instrument recorded the encounter with the bow shock over the course of about two hours on June 24, 2016.
Plasma Waves: Plasma waves which sound like a roaring ocean surf create a rhythmic cacophony. EMFISIS instrument aboard NASA’s Van Allen Probes helped capture the sound.
Saturn’s Radio Emissions: Saturn which is a source of intense radio emissions is monitored by the Cassini spacecraft. The radio waves are closely related to the auroras near the poles of the planet.
Sounds of Jupiter: At times, scientists translate radio signals into sound to understand the signals in a better way. This approach is called “data sonification”. The Galileo spacecraft made the first flyby of Jupiter’s largest moon, Ganymede on June 27, 1996. This audio track represents data from Galileo’s Plasma Wave Experiment instrument.
Sounds of a Comet Encounter: In thus audio track, the sound on dust particles and small rocks pelting on the protective shield on NASA’s Stardust spacecraft, a flyby of comet Tempel can be heard. You can hear the compilation here.
