Who would have thought that Ganymede, one of Jupiter’s many moons, looks like Brian Eno album?
A research landfill in the Juno Orbiter has given every space nerd a happy holiday gift: the sights and sounds of the largest planet in our solar system and its largest moon. Images of the swirling gas giant’s “surface” are as brilliant and graphic as Jupiter-watchers would expect, but the real treat is this audio track.
Captured by Juno’s Waves instrument, which measures electrical and radio waves from a planet (or the moon, in this case) magnetosphere, the 50-second clip makes positive sounds from another world. The researchers believe there is a simple explanation for the sudden jump into a significantly higher pitch in about 30 seconds.
“This soundtrack is wild enough to make you feel like you’re riding as Juno walks past Ganymede for the first time in more than two decades,” said Scott Bolton, Principal Investigator of Project Juno, at the NASA reveal. “If you listen closely, you can hear the sudden change to higher frequencies in the middle of the recording, which represents the entry into a different region of the Ganymede magnetosphere.”
Another principal investigator on the project, William Kurth of the University of Iowa, believed that the change in frequency was the result of “Juno’s shift from the night side to the day side at Ganymede”.
To be clear: This doesn’t mean you’ll hear what’s in the recording that NASA shares if you somehow find yourself on Ganymede’s surface. The magnetic and radio waves collected by Juno are only data points; The NASA team is tasked with moving their frequency into a range that most people can hear without assistance.
Waves recordings were collected in June 2021 during the same Juno Bridge that left us This amazing new photo of Ganymede during summer.
The drop in Juno data has also given us a pair of fresh insights into Jupiter. This, collected November 29, could easily be an artist’s interpretation of the planet.

This is not the case, however. The image, captured by Juno’s “Visible Light Imager,” offers a glimpse of two storm systems orbiting the planet.
Another image of Jupiter comparing one of the planet’s storms to an algal bloom on Earth that occurred in the Norwegian Sea, captured by a satellite image. The comparison was made by Lia Siegelman, an oceanographer who sees space images like this as an opportunity to elicit a better understanding of Earth’s oceans.

“When I saw the richness of the turbulence surrounding Hurricanes Jovian, with all the threads and little eddies, it reminded me of the turbulence you see in the ocean around the eddies,” Siegelman said. This is particularly evident in high-resolution satellite images of eddies in Earth’s oceans revealed by plankton blooms that act as a flow-tracker.
