You’ve heard the creaks, cracks, and cackling noises of our universe before. Using data from our spacecraft, our scientists gathered NEW sinister sounds from the depths of space in time for Halloween.
 
Listen to our playlist filled with new “moans” and “whistles” from our universe that would scare the most ghoulish of creatures.

Measurements collected by the Waves instrument aboard NASA’s Juno spacecraft during its close flyby of Jupiter’s moon Europa on Sept. 29, 2022 have been converted to an audible frequency. The variation of frequency of the plasma waves observed near Europa can be heard as the plasma density varies.

The system called R Aquarii contains two stars — a white dwarf and a red giant — in orbit around each other. In a composite visual image, Hubble data (red and blue) reveal spectacular structures that are evidence of outbursts generated by the pair of stars buried at the center of the image. X-rays from Chandra show a jet from the white dwarf banging into the material surrounding it and creating shock waves. In the sonification of R Aquarii, the piece evolves as a radar-like scan of the image, clockwise starting at the 12 o’clock position. The volume changes in proportion to the brightness of sources in Hubble’s visible light and Chandra’s X-ray image, while the distance from the center dictates the musical pitch (higher notes are farther out). The deep thuds toward the four corners are “diffraction spikes,” which are artifacts from the bright central star. Listeners can hear jets from the white dwarf as the cursor travels near the two o’clock and eight o’clock positions. The ribbon-like arcs captured by Hubble create a rising and falling melody that sounds similar to a set of singing bowls (metal bowls that produce different sounds and tones when struck with a mallet), while the Chandra data are rendered to sound more like a synthetic and windy purr.

MSH 15-52 is a cloud of energized particles blown away from a dead, collapsed star. This image includes X-rays from NASA’s Chandra X-ray Observatory (orange, green and blue) as well as the Imaging X-ray Polarimetry Explorer, or IXPE (purple). X-ray data have been combined with infrared data from the Dark Energy Plane Survey 2 (red and blue). In sound, the scan goes from the bottom to the top. The brightness of the Chandra data of the cloud has been converted into rough string-like sounds, while the blast wave is represented by a range of pitches of firework-type noises. The IXPE data are heard as wind-like sounds. The infrared data are mapped to musical pitches of a synthesizer sound. The light curve, or brightness over time, from the dead star’s collapsed core is heard in pulses that occur almost 7 times every second as it does in the original data.

IC 443 is a supernova remnant, or the debris of an exploded star, which astronomers have nicknamed the Jellyfish Nebula. A visual composite image of IC 443 includes X-rays from NASA’s Chandra X-ray Observatory (cyan) and German ROSAT X-ray telescope (blue) along with radio data from the NSF’s Very Large Array (green) and optical data from the Digitized Sky Survey (red). The sonification of IC 443 begins with a top-down scan as the brightness of the data is correlated to the volume of the sound. The sounds are mapped to colors in the image with red light being heard as lower pitches, the green as medium, and the blue light as the higher pitches. This creates notes that sweep up and down in pitch continuously. Several colors are isolated and control the volume of sustained tones with red controlling the lowest note and white controlling the highest note. The background stars in the optical image have been converted to water drop sounds in the sonification.

The Vela Pulsar data has also been converted to sound through a process called data sonification. In this sonification, listen to a radar-like scan, clockwise from 12:00 of the image. Brightness is mapped to volume. Distance from the center is mapped to pitch (farther away is higher pitch). For the Chandra X-ray data, the bright inner region (violet) is mapped to a low synth sound, with 11 Hz oscillations matching the period of the pulsar. The dimmer outer region (blue) and jet are mapped to a wind-like sound. A long upper jet can be heard around 4 seconds in, and a bright, but much shorter lower jet can be heard around 20 seconds. For the Hubble optical data, the stars are mapped to notes on a plucked-type synth (where brighter stars are louder, and stars farther from the center are higher pitched).
