Data Sonification: Pismis 24

  • Released Tuesday, November 29, 2022

Pismis 24 is a stunning star cluster that lies within the nebula NGC 6357, which resides about 8,000 light-years away. In this sonification of the Hubble image, a top-down scan maps brightness to volume and pitch for both the stars and nebula.

The stars are assigned to musical pitches played on a classical guitar (brighter stars are louder and higher pitched), and the nebula uses a continuous range of frequencies (brighter regions are louder and higher pitched). Red, green, and blue channels are mapped to low, medium, and high frequency ranges respectively.
