Thanks to Mark Heyer from the University of Massachusetts Amherst, we now have a jazzy tune reflecting the Milky Way’s rotation in a nice tune.

The notes reflect the velocities of the gas rotating around the centre of our galaxy and were “composed” by a pentatonic minor scale that went through 20yrs of radio telescopic data on gas in our galaxy.

The gases filling the interstellar medium appear in the three phases of atomic, molecular and ionised; furthermore, they move either towards or away from Earth. Based on their spectra, they were “translated” into musical instruments of different sorts (molecular equalled woodblocks and piano, atomic ones were translated into acoustic bass, and saxophone was the translation of ionised gases).
