The core of our Milky Way galaxy is densely packed with gas, dust, stars, and stellar remnants, but its centerpiece is a monster black hole with a mass of 4 million Suns called Sagittarius A* (pronounced “A-star”).

This sonification tracks an image of the galactic center captured by NASA’s Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope in X-ray, optical, and infrared light, respectively. A different instrument represents each observatory, with a xylophone for Chandra, a violin for Hubble and a soft piano for Spitzer. The translation begins on the left side of the image and moves to the right, with sounds representing the positions and brightness of the sources. The light of objects located toward the top of the image have higher pitch, while the intensity of the light controls the volume. Stars and compact sources emerge as individual notes, while extended clouds of gas and dust produce an evolving drone. A crescendo happens in the brightest region of the image, where the supermassive black hole resides. The Hubble image outlines energetic regions where stars are being born, while Spitzer’s infrared data show glowing clouds of dust containing complex structures. X-rays from Chandra reveal gas heated to millions of degrees from stellar explosions and outflows from Sagittarius A*.

Galactic Center Sonification

The joint ESA/Jaxa BepiColombo mission flew past Mercury for the first time on 1 October 2021, capturing data with the magnetometer onboard ESA’s Mercury Planetary Orbiter. A sonification of the magnetic field data is presented here.  
 
Two synthesizers can be heard, which are controlled by three characteristics of the magnetic field. The first synthesizer's pitch represents the slowly changing magnitude of the background magnetic field. First the solar wind is heard, then the increase and decrease of the planetary magnetic field, and then the solar wind again. The lower the pitch, the more intense the magnetic field. 
 
The pitch of the second synthesizer is controlled by the variations of the magnetic field magnitude. A more turbulent magnetic field is represented by a faster change in pitch. The magnetosheath crossing after closest approach is very prominent. 
 
Using the amplitude envelope as a control for the volume of the second synthesizer emphasises the different magnetospheric regions.

Transplant Rejection

Pre-order

Nikolajev - Remorse (Muscut 24C, Cass, 2022)

A near-infrared image of the Cosmic Cliffs in the Carina Nebula, captured by NASA’s Webb Telescope, has been mapped to a symphony of sounds. This track includes sounds from just the top half of the image, which resembles a dark blue night sky. The gas and dust that are represented in blue hues have been translated to windy, drone-like sounds. The sonification scans the image from left to right.
 
This sonification does not represent sounds recorded in space. Two musicians mapped the telescope’s data to sound, carefully composing music to accurately represent details the team would like listeners to focus on. In a way, this sonification is like modern dance or an impressionist painting – it converts Webb’s image to a new medium to engage and inspire listeners.

Brighter light in the image is louder. The vertical position of light also dictates the frequency of sound. For example, bright light near the top of the image sounds loud and high, but bright light near the bottom is loud and lower pitched.

Webb’s Cosmic Cliffs Sonification: Sky

NASA’s Webb Telescope uncovered two views of the Southern Ring Nebula – in near-infrared light (at left in the track image) and mid-infrared light (at right in the track image) – and each has been adapted to sound.

In this sonification, the colors in the images were mapped to pitches of sound – frequencies of light converted directly to frequencies of sound. Near-infrared light is represented by a higher range of frequencies at the beginning of the track. Mid-way through, the notes change, becoming lower overall to reflect that mid-infrared includes longer wavelengths of light.
 
Listen carefully at 15 seconds and 44 seconds. These notes align with the centers of the near- and mid-infrared images, where the stars at the center of the “action” appear. In the near-infrared image that begins the track, only one star is heard clearly, with a louder clang. 

In the second half of the track, listeners will hear a low note just before a higher note, which denotes that two stars were detected in mid-infrared light. The lower note represents the redder star that created this nebula, and the second is the star that appears brighter and larger.

Webb’s Southern Ring Nebula Sonification

The Voyager 1 spacecraft has experienced three "tsunami waves" in interstellar space. Listen to how these waves cause surrounding ionized matter to ring. More details on this sound can be found here: http://www.nasa.gov/jpl/nasa-voyager-tsunami-wave-still-flies-through-interstellar-space/

Plasmawaves - Chorus

One year and three trips around the Sun later, NASA's Parker Solar Probe heard some weird, sci-fi sounds from plasma within the solar wind -- and those sounds may answer unanswered questions about how the wind forms.
