This recording was made by the SuperCam instrument on NASA’s Perseverance Mars rover on Feb. 19, 2021, just about 18 hours after landing on the mission’s first sol or Martian day. The rover’s mast, holding the microphone, was still stowed on Perseverance’s deck, and so the sound is muffled, a little like the sound one hears listening to a seashell or having a hand cupped over the ear. Just a little wind can be heard.

First Audio Recording of Sounds on Mars

Blazars are galaxies whose central supermassive black hole, weighing millions to billions of times our Sun’s mass, blasts a particle jet almost directly toward us at nearly the speed of light.

This track sonifies a decade of gamma rays from the blazar TXS 0506+056 detected by NASA’s Fermi Gamma-ray Space Telescope between August 2008 and May 2018. The percussive sounds match the energy of the detected gamma rays. Unprecedented flaring activity began in April 2017 and continued for months. On Sept. 22, 2017, an observatory at the South Pole detected a high-energy neutrino thought to have originated from the blazar.

Blazar Flare Sonification

This track sonifies the Chandra Deep Field South, the deepest X-ray exposure ever made, comprising over 81 days of observations with NASA’s Chandra X-ray Observatory. 

Moving from bottom to top, the colors in the image determine the tones played. More specifically, colors toward the red end of the rainbow rumble as lower tones, while colors containing more purple play as higher ones. White areas in the image are heard as white noise. Almost all of the sources represented in the image are black holes or galaxies. Most of the former are supermassive black holes that reside at the centers of galaxies. The wide range of musical frequencies represents the full range of X-ray colors collected by Chandra from this region. Note that as the piece scans upward, the stereo position of the sounds provides clues about the position of the sources from left to right.

Chandra Deep Field Sonification

Messier 51 (M51) is perhaps better known by its nickname of the Whirlpool Galaxy because its face-on orientation to Earth reveals its wound-up spiral arms. This gives telescopes here a view of another spiral galaxy similar to our Milky Way, whose structure we cannot observe directly from our position within it. The sonification tracks along a line emanating from the galaxy's core to the edge of the image and scanning clockwise. The light encountered by this line has been mapped to the notes of a melodic minor scale. The sequence represents X-ray data from NASA’s Chandra X-ray Observatory.

The bright core, which harbors a supermassive black hole, produces a constant low hum punctuated by short sounds from compact bright sources within the galaxy, including many stellar-sized black holes.

M51 X-ray Sonification

Listen to the rhythms of the pulsating red giant star called 74 Draconis based on brightness measurements from NASA’s Transiting Exoplanet Survey Satellite. Just below the surfaces of these stars, hot gas rises, cools, and then sinks, where it heats up again, much like a pan of boiling water on a hot stove. This motion produces waves of changing pressure – sound waves. The interaction of these waves results in orderly motion called standing waves that create measurable changes in the star’s brightness. Larger stars produce longer oscillations and thus have deeper tones. To produce audible tones, astronomers multiplied its oscillation frequency by 3 million times.

Red Giant Star 74 Draconis Pulsation

When a star like the Sun begins to run out of helium to burn, it will blow off huge clouds of gas and dust. These outbursts can form spectacular structures such as the one seen in the Cat's Eye nebula. This image of the Cat's Eye contains both X-rays from Chandra around the center and visible light data from the Hubble Space Telescope, which show the series of bubbles expelled by the star over time. To listen to these data, there is a radar-like scan that moves clockwise emanating from the center point to produce pitch. Light that is further from the center is heard as higher pitches while brighter light is louder. The X-rays are represented by a harsher sound, while the visible light data sound smoother. The circular rings create a constant hum, interrupted by a few sounds from spokes in the data. The rising and falling pitches that can be heard are due to the radar scan passing across the shells and jets in the nebula.  (Credit: NASA/CXC/K. Arcand and SYSTEM Sound/M. Russo & A. Santaguida, 2021)

Cat's Eye Nebula Sonification

Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note — one that humans cannot hear some 57 octaves below middle C. Now a new sonification brings more notes to this black hole sound machine. A new sonification — that is, the translation of astronomical data into sound — is being released in time for NASA’s Black Hole Week this year.

In some ways, this sonification is unlike any other done before because it revisits the actual sound waves discovered in data from NASA’s Chandra X-ray Observatory. The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through. A galaxy cluster, on the other hand, has copious amounts of gas that envelops the hundreds or even thousands of galaxies within it, providing an avenue for the sound waves to travel.

In this new sonification of Perseus, the sound waves that were previously identified were extracted and made audible for the first time. The sound waves were extracted in radial directions, that is, outwards from the center. The signals were then resynthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch. Another way to put this is that they are being heard 144 and 288 quadrillion (1,000,000,000,000,000) times higher than their original frequency. The radar-like scan around the image allows you to hear waves emitted in different directions. In the visual image of these data, blue and purple both show X-ray data captured by Chandra.

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.

R Aquarii Sonification

What does space sound like? It’s a question that’s fascinated composers and scientists alike throughout history. Through a process called data sonification, heliophysicists are using NASA satellites like audio recorders to listen to the electromagnetic symphony our Sun plays on the strings of Earth’s magnetic field, and making new discoveries along the way. Learn how you can join heliophysicist Mike Hartinger and sonification specialist Robert Alexander in listening to Earth's “magnetic harp” in a new NASA citizen science initiative.

New research from the up-close Grand Finale orbits of NASA’s Cassini mission shows a surprisingly powerful interaction of plasma waves moving from Saturn to its moon Enceladus. Researchers converted the recording of plasma waves into a “whooshing” audio file that we can hear -- in the same way a radio translates electromagnetic waves into music. Much like air or water, plasma (the fourth state of matter) generates waves to carry energy. The recording was captured by the Radio Plasma Wave Science (RPWS) instrument Sept. 2, 2017, two weeks before Cassini was deliberately plunged into the atmosphere of Saturn.
