Listen to the ‘sound’ of Jupiter’s moon Ganymede because of the Juno probe | Engadget

You’d suppose moons could be quiet in comparison with their host planets, however that is not fully true — if you know the way to hear. The principal investigator for NASA’s Juno mission, Scott Bolton, has produced an audio recording of magnetic area exercise round Jupiter’s moon Ganymede because the Juno spacecraft flew previous on June seventh, 2021. The 50-second clip reveals a pointy change in exercise because the probe entered a unique a part of Ganymede’s magnetosphere, probably because it left the evening aspect to enter the daylight.

The audio got here from shifting electrical and magnetic frequencies into the audible vary. Jupiter’s magnetosphere dominates that of its moons and is current within the recording, however Ganymede is the one moon within the Solar System to have a magnetic area (probably as a consequence of its liquid iron core). This is not a feat you can replicate elsewhere within the close to future.

The soundtrack was half of a bigger Juno briefing the place the mission group revealed essentially the most detailed map but of Jupiter’s magnetic area. The information confirmed how lengthy it could take the Great Red Spot and the equatorial Great Blue Spot to maneuver across the planet (roughly 4.5 years and 350 years respectively). The findings additionally confirmed that east-west jetstreams are ripping the Great Blue Spot aside, and that polar cyclones behave very like ocean vortices on Earth.

You would not hear these sounds if you happen to might go to Ganymede your self. However, they seem to be a reminder that even seemingly useless worlds are ceaselessly brimming with exercise you may detect utilizing the correct devices. It’s only a query of how straightforward it’s to note that exercise.
