With the process of sonification, different pitches attached to various ‘lights’ in an astronomical image can be conveyed in interesting and novel auditory ways. This clip, which shows what the Helix Nebula would ‘sound’ like, is giving Instagram users goosebumps.
The caption of the post details what it shows. It reads, “The Helix Nebula is 655 light-years away from us, and 3 light-years across! Near the end of a Sun-like star’s life, nebulae like this form when the star sheds some of its outer material”.
“In this sonification, red light is assigned lower pitches and blue light is assigned higher pitches. Just as the frequencies of light increase from red to blue, frequencies of sound increase from low to high pitches. While there’s no sound in space, sonifications like this help us conceptualize the data in astronomical images in a new, auditory way!” the text explains.
