The piece, titled “Where Parallel Lines Converge,” goes beyond artistic inspiration — it’s a representation of actual NASA data.
NASAComposer Sophie Kastner has translate a composite picture of the center of the Milky Way into a symphonic piece that can be performed by instrumentalist .
Have you ever wondered what the center of the Milky Way galaxy sounds like ? Now , thanks to three NASA telescopes and collaboration with composers and instrumentalist , you could hear a musical interpretation of the information being emitted by the cosmos .
The projection is the inspiration of Dr. Kimberly Arcand , an expert in astronomy visualization at the Center for Astrophysics , Harvard & Smithsonian .
NASAComposer Sophie Kastner has translated a composite image of the center of the Milky Way into a symphonic piece that can be performed by musicians.
In its raw grade , much of NASA ’s telescopic data , including X - ray and infrared light , is invisible to the human eye . Usually , scientists change over this data into colourful , starry images .
“ It dawn on me quite a few years back that that was prioritizing a visual when it was n’t necessarily always the best display case or the only suit that that should be created , ” Arcand said in an interview withSmithsonian Magazine . “ Why could n’t we use some other sense to be able to explore this data , peculiarly for people who are unsighted or low vision ? ”
At first , Arcand experimented with using tactile models , such as Lego blocks , to represent the data in a new mode . But after the COVID-19 pandemic squeeze her and her squad to go digital , Arcand team up with instrumentalist and sound engineers from System Sounds , a science and art outreach undertaking .

Using computers to mathematically map out the datum , they created auditive role model , predict sonifications , for several astronomic trope . The idea was to transform the unknowable telescopic data point into sounds attender might be able to perceive and interpret .
High - pitch sound represent Light Within in the top section of the image , while low - pitched speech sound depict the bottom section . How undimmed the lighter is determines the volume , and the data from each of the three telescopes used to create the sonifications is played by a different solidifying of instruments .
But the undertaking did n’t stop there . Arcand said that when she gave talking about the sonifications , musicians would ask if they could play the piece . So she reached out to composer Sophie Kastner to turn one of the sonifications into a playable piece .
“ As an artist and a musician , I was fascinated by the idea of consider something that ’s scientific and turning it into art or music , ” Kastner said . “ Those two thing are n’t as far removed as one might think . ”
Kastner was given a composite icon of the heart of the Milky fashion Galaxy and tasked with read it into song . She see it into a small ensemble typography of string , woodwind , percussion , and pianoforte , titled “ Where Parallel Lines Converge . ”
“ It ’s like a committal to writing a fictitious report that is mostly based on real facts , ” Kastner said in astatement . “ We are train the datum from place that has been translated into sound and place a unexampled and human twist on it . ”

In creating the firearm , Kastner said she near it almost as if she were writing a film grade for the photo . She broke the image into three pocket-sized sections , and create a narrow - long audile “ vignette ” for each one . Kastner say she wanted to convey a “ vastness , or a sense of endlessness … feel small in compare to something so vast . ”
In the piece of music , different types of data point are represented with different instruments , tones , and registers . For illustration , star are represented by sharp staccato billet , while foggy or cloud - like anatomical structure get long , free burning government note . X - shaft data is represented by a gamey - register , shining tone , while infrared data has a humbled , darker tone .
The “ crescendo ” of the piece is the supermassive mordant hole — the bright office near the image ’s lower good corner .
The composition was recorded by Ensemble Eclát , an orchestra from Montreal , at McGill University earlier this year . The bed sheet euphony is available to download for free .
Now , Kastner and Arcand trust to keep on and expand the project . Kastner say she would wish to develop the piece into a tenacious composition or to write more pieces like it .
“ In some way , this is just another elbow room for humans to interact with the night sky just as they have throughout immortalize account , ” Arcand said . “ We are using dissimilar tool but the construct of being inspired by the heavens to make art rest the same . ”
After reading about this musical interpretation of the galaxy , listen tonine of the most persistent sounds ever recorded . Or , listen towhat a seismic quake on Mars sounds like .
