… and you have a nice long melody. Who knew? 🙂

GÉANT, the pan-European data network serving 50 million research and education users at speeds of up to 500Gbps, has harnessed the data collected by two spacecraft over a period of 36 years to create a new piece of classical music.

Launched in 1977, both Voyager 1 and Voyager 2 are now decommissioned but still recording and sending live data to Earth. They continue to traverse different parts of the universe, billions of kilometres apart, with Voyager 1 actually leaving our solar system last year.

In order to compose the duet, 320,000 measurements were selected from each spacecraft at one hour intervals.

That data was then converted into two “very long” melodies, each comprising 320,000 notes using different sampling frequencies, from a few KHz to 44.1 kHz.
