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

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.

Dark Ambient Transitions: A Winter-Light Mix by Ajna

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.

Audio from NASA’s Juno Mission: Europa Flyby

This image shows the region around the Milky Way's central supermassive black hole, known as Sagittarius A* (Sgr A*), in infrared (orange and purple) and X-ray light (blue). The image is scanned from left to right and the data are transformed into sound. The brightness of the objects is represented by the volume, while the vertical positions of the sources in the image are mapped to musical pitches. X-rays are played with a soft synthesizer and the infrared data are heard as bass notes and plucked sounds. The brightest region in the middle of the image (and hence the loudest) is where Sgr A* the black hole, resides. It is within this area that the Event Horizon Telescope was able to peer to obtain the first image of Sgr A* itself.

Plasmaspheric Hiss

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.
