Chandra X-ray Observatory | Data Sonification: M74 / Phantom Galaxy (Composite) @ChandraXray | Uploaded 7 months ago | Updated 1 day ago
Messier 74 is a spiral galaxy like our Milky Way, which is seen face-on from Earth’s vantage point some 32 million light-years away. X-rays from Chandra (purple) have been combined with an infrared view of M74 from NASA’s James Webb Space Telescope (green, yellow, red, and magenta) as well as optical data from NASA’s Hubble Space Telescope (orange, cyan, and blue). In sonifying these data, a clockwise-moving radar-like scan starts around 12 o’clock. The distance from the center controls the frequencies of sound with light farther from the center being higher pitched. The Chandra sources correspond to relatively high musical pitches of glassy ethereal and clear plucked sounds. In the Webb data, large, medium, and small features are represented by low, medium, and high frequency ranges of pitches respectively with the brightest stars being heard as percussive sounds. The Hubble data have been turned into breathy synthesizer sounds along with thin metallic plucked sounds for bright stars and clusters.
