An Italian scientist has taken 37 years worth of data from both Voyager space probes and turned it into music.
The composer, Domenico Vicinanza, is a project manager at Géant — Europe's high-speed data network that powers Cern and the Large Hadron Collider.
He used 320,000 individual measurements of cosmic particle data taken at one-hour intervals using the spacecrafts' cosmic ray detector.
To make this data sound musical, Vicinanza mapped different frequencies, or detections, to different frequencies of a note. And to distinguish between the two spacecraft, he created a kind of duelling duet by giving each probe its own arrangement and sound texture.
"I wanted to compose a musical piece celebrating the Voyager 1 and 2 together, so used the same measurements (proton counts from the cosmic ray detector over the last 37 years) from both spacecrafts, at the exactly same point of time, but at several billions of kilometres of distance one from the other,"
