Two researchers, Dr. Domenico Vicinanza of Anglia Ruskin University and Dr. Genevieve Williams, have “sonified” a video of the 5,000th Martian sunrise captured by the Mars rover, Opportunity. The music is a representation of the experience of seeing the sun rise over the red dunes as light pierces the planet’s atmosphere.
From the release:
Researchers created the piece of music by scanning a picture from left to right, pixel by pixel, and looking at brightness and colour information and combining them with terrain elevation. They used algorithms to assign each element a specific pitch and melody.
The quiet, slow harmonies are a consequence of the dark background and the brighter, higher pitched sounds towards the middle of the piece are created by the sonification of the bright sun disk.
