In case you didn’t know, NASA has an ongoing sonification effort that translates visual data into sounds. The result gives people a different way to experience a particular image including the observations from different space missions. NASA has released three new music that covers three space scenes.
The latest releases from NASA feature Cat’s Eye Nebula, Whirlpool Galaxy, and Chandra Deep Field South. As expected, the original content from space observations wasn’t altered during the sonification process. Furthermore, NASA explained that the agency used different music to represent different sounds.
First of the released video, the red colors are presented as low tones; the purple colors are higher tones and white noise to represent the white colors. Although the image seems fairly simple, the result is pretty stunning as it represents a long-duration observation made by Chandra X-ray Observatory.
NASA revealed that the music covers the entire frequency range observed by the X-ray observatory. The space agency explained, “Played as sound, however, the full range of data can be experienced. As the piece scans upward, the stereo position of the sounds can help distinguish the position of the sources from left to right.”
Apart from the music associated with Chandra laboratory, the agency released two more projects that feature Whirlpool Galaxy and the Cat’s Eye Nebula. In case you’re interested, you can check out other sonification projects here.
