Have you ever wondered what outer space would sound like? Well the National Aeronautics and Space Administration, better known as The NASA, He took on the task of knowing what galaxies specifically sound like.
The space agency managed to find out what they sound like thanks to the images captured by Hubble Telescope, that have been transformed into sounds by professional musicians.
NASA explained that through data sonification, the digital data that are translated into images, they can transform into sound.
To image elements, such as the brightness and position, They are assigned tones and volumes, so sonifications provide a new way to experience and conceptualize data.
What do galaxies sound like?
The space agency carried out the sonification of what they called “Arp 140”, a pair of interacting galaxies.
The leftmost galaxy is a barred spiral galaxy known as NGC 275, and the galaxy on the right side is a lenticular galaxy called NGC 274.
The scientists sonified the data in this image, assigning tone to image color as a whole (the bluest light is the highest note, the reddest light is the lowest note).
Hue is assigned to the brightness of resolved stars and background galaxies, based on their apparent size: objects that appear larger In the photography They have lower tones and the Smaller objects have a higher pitch.

Sonifications allow the audience, including blind communities and visually impaired, “listen” to astronomical images and explore your data.
