The Whirlpool Galaxy (M51) is named for its face-on orientation to Earth, which reveals its winding spiral arms. The sonification begins at the top of the image and moves radially around the image in a clockwise direction. The radius is mapped to notes of a melodic minor scale. Each wavelength of light in the image is mapped to a limited range of pitches, from low to high pitch, which corresponds to low to high light frequency: infrared, optical, ultraviolet, and then X-ray. The sequence begins with sounds from all four types of light, but then separately moves through the data from Spitzer (infrared), Hubble (visible), GALEX (ultraviolet), and Chandra (x-ray). At wavelengths in which the spiral arms are prominent, the pitches creep upward as the spiral reaches farther from the core. A constant, low hum associated with the bright core can be heard, punctuated by short sounds from compact sources of light within the galaxy.
