Cosmic Jingles: "Listen" to Euclid Space Telescope’s Image of Nebula M78 in Orion

Cosmic Jingles: "Listen" to Euclid Space Telescope’s Image of Nebula M78 in Orion

An ethereal dance of misty clouds of interstellar dust with a myriad of distant stars and galaxies speckled like paint drops over a black canvas. This is a sonification of a breathtaking image taken by the European Space Agency's Euclid space telescope of the young star-forming region Messier 78. 

The sonification offers a unique representation of the data collected by Euclid. It lets us explore the stellar nurseries in M78 through sound. Close your eyes and listen to let the cosmic image be drawn by your mind’s eye, or watch as the traceback line in this video follows the sounds to color the image from left to right.  

The twinkling sounds of pitches and volumes represent the galaxies and stars in the frame. The pitch of the sound points towards where we see the dot of light in the image. Higher pitches tell us that a star or galaxy appears further at the top in the image along the traceback line.  

The brightness of these objects in and around M78 are represented by the volume of the twinkles. Whenever we hear a particularly loud clink, the star or galaxy that Euclid observed appears particularly bright in the image. 

Underlying these jingling sounds, we can hear a steady undertone, made up of two chords which represent regions in Messier 78. This sound intensifies as the traceback line approaches first the brightest, and later the densest regions in the nebula.  

The first two deeper crescendos in this undertone indicate two patches in the image where the most intense color is blue/purple. These appear as two ‘cavities’ in M78, where newly forming stars carve out and illuminate the dust and gas in which they were born. 

The chords intensify a third time at a slightly higher pitch corresponding to the red-orange colors in the image, as the sound draws over the densest star-forming region of the frame. This stellar nursery is hidden by a layer of dust and gas that is so thick that it obscures almost all the light of the young stars within it.  

As the sound traces over the entire Euclid image, these different tones together form a cosmic symphony that represents the image of Messier 78, and the stars and galaxies that lie behind and within it.

Image Description: A filamentary orange veil covers a bright region of star formation. The background is dark, stippled with stars and galaxies ranging from small bright dots to starry shapes. The foreground veil spans from upper left to the bottom right and resembles a seahorse. Bright stars light up the ‘eye’ and ‘chest’ regions of the seahorse with purple light. Within the tail, three bright spots sit in a traffic-light like formation.
