Nearfield - Cold Depths Of Cosmos

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.

Sound of the solar wind at Mercury

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.

UPDATE (20 Aug 2015): What made the comet sing? Scientists working on Rosetta's RPC instrument have found out why 67P/C-G was singing. Via http://wp.me/p46DHN-1nN

ORIGINAL Citation (Oct 2014): Rosetta’s Plasma Consortium (RPC) has uncovered a mysterious ‘song’ that Comet 67P/Churyumov-Gerasimenko is singing into space. The comet seems to be emitting a ‘song’ in the form of oscillations in the magnetic field in the comet’s environment. It is being sung at 40-50 millihertz, far below human hearing, which typically picks up sound between 20 Hz and 20 kHz. To make the music audible to the human ear, the frequencies have been increased in this recording. This sonification of the RPC-Mag data was compiled by German composer Manuel Senfft (www.tagirijus.de).  Read full details in ESA's Rosetta blog: http://wp.me/p46DHN-Li

A Singing Comet

Sven's compositions often transport listeners to inspiring, ethereal realms. Cellos and pianos paint soft, contemplative landscapes, tinged with underlying angst and longing, showcasing Sven's talent for translating life stories into relatable and evocative music.

With 'The Undefined Feeling of Discomfort', Sven presents an album this time brimming with anxiety, fear, and anticipation. Struggle permeates the music, enhanced by distorted vocals, acoustic guitars and drone pads. Sven once again evokes deep emotions, guiding the listener through a powerful sonic journey.

The album opens with a floating, introspective tone. The atmosphere is dark, and an anxious feeling gradually emerges. As the first city lights appear from afar, a tumultuous force sweeps everything away, like an undertow shattering waves on a coastline. Moving on, choir-like vocals bring in a biblical aspect, adding darker, soul-wrenching depth. It feels like a scream from the abyss, leaving an empty shell resonating with its vastness. Soft guitar notes offer hope, but the passage ends with intense anxiety, and feelings of rapid flashes before one's eyes throwing us off balance.

Further along, a rise from uncertainty hints at a resolution. It starts with a sense of battle and resistance illustrated with hopeful strings and a heartbeat-like backbeat. A force emerges from the dark sonic cloud pierced by a tenacious sun. The second half brings resolution and lightness, offering hope and comforting certainty amidst the alarming tension of this transitional phase. The album leaves us feeling chaos after the storm, atoms crushing into one another. With a calmer end, as if the initial rumble had passed, a scar remains. The memory lingers, but things move forward. 

The Undefined Feeling of Discomfort

wlr180 Sven Laux - The Undefined Feeling of Discomfort

Data from the European Space Agency and NASA’s Solar and Heliospheric Observatory (SOHO) has captured the dynamic movement of the Sun’s atmosphere for over 20 years. Today, we can hear the Sun’s movement — all of its waves, loops and eruptions — with our own ears.

This story incorporates data sonified by the Stanford Experimental Physics Lab and music from Lee Rosevere.

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.
