More crazy sounds from Jupiter have emerged as the 2021 came to an end.

NASA has published audio recorded in June during a close flyby of Jupiter's largest moon, Ganymede. Scientists used a Waves instrument, which was specially designed to understand fields and particles in Jupiter's magnetosphere.

Scott Bolton, the Principal Investigator of NASA's Juno mission, recently released a 50-second audio track of electric and magnetic radio waves produced in Jupiter's magnetosphere during a presentation in New Orleans.

The recording starts with some scratchy sound, but as the Waves instrument spins on its axis into "view" of Jupiter, you can hear some crazy sounds. The droning static turns into something that sounds like alien music as the Waves instrument orbits Jupiter.

There are some "voices" in the tone, and when NASA representatives played this for me over the phone, I thought I heard a few voices saying things like "NASA," "radio," and "waves." But to be honest… it actually sounded more like static, and I couldn't make out any discernable words.

It's certainly interesting to listen to, though!

The Juno spacecraft arrived at Jupiter on July 4th after a five-year journey through deep space. The probe is equipped with several instruments that are capturing fascinating data about the largest planet in our solar system.

NASA will be releasing more recordings of the Waves instrument as the mission continues, and will also be releasing annotated audio with identifying sounds from Jupiter's moons.

Juno is currently in a highly-elliptical orbit around Jupiter that takes it within 5,000 kilometers of the cloud tops of the planet. The spacecraft takes 53 days to complete one orbit. Juno will eventually transition into a much closer, polar orbit around Jupiter.

This mission will help to reveal key insights about the planet's origins, structure, atmosphere and magnetosphere.Jupiter is home to 67 moons. Scientists are particularly interested in studying Ganymede, which is thought to have an ocean of liquid water beneath its surface that could potentially support life as we know it.
