IC 433 is a supernova remnant, or the debris of an exploded star, which astronomers have nicknamed the Jellyfish Nebula. A visual composite image of IC 433 includes X-rays from NASA’s Chandra X-ray Observatory and German ROSAT X-ray telescope (blue) along with radio data from the NSF’s Very Large Array (green) and optical data from the Digitized Sky Survey (red). The sonification of IC 433 begins with a top-down scan as the brightness of the data is correlated to the volume of the sound. The sounds are mapped to colors in the image with red light being heard as lower pitches, the green as medium, and the blue light as the higher pitches. This creates notes that sweep up and down in pitch continuously. Several colors are isolated and control the volume of sustained tones with red controlling the lowest note and white controlling the highest note. The background stars in the optical image have been converted to water drop sounds in the sonification. Sonification: NASA/CXC/SAO/, SYSTEM Sounds (M. Russo, A. Santaguida) More at:
