Measurements by NASA’s two Voyager spacecraft helped reveal the outer planets of the solar system and then the doorsteps to interstellar space. Now, their data has been used to create a piece of classical music.

Physicist Domenico Vicinanza, product services manager at Europe’s high-speed GEANT computer network, selected 320,000 measurements from each of the two spacecraft and processed the data to create a duet.

“I used different groups of instruments and different sound textures to represent the two spacecraft,” Vicinanza  said in a statement.

Vicinanza, who also is a musician, chose proton counts from the Voyagers’ cosmic ray detectors taken simultaneously at one-hour intervals when the spacecraft were billions of miles apart from one another.

“I wanted to compose a musical piece celebrating the Voyager 1 and 2 together,” he said.

The result is a beautiful, upbeat five-minute composition, but the score has some scientific value too.

“Analyzing the melody is exactly the same as looking at data in a spreadsheet, but using the ear,” Vicinanza added.

Vicinanza  previously has created music from Voyager 1, which last year became the first human-made object to leave the solar system, and from the Large Hadron Collider, brain scans and volcanoes.
