Jupiter's moon may have been a planet.
It's one of the most intriguing places in the neighborhood because it's the largest moon in our Solar System. It's great because Jupiter probe Juno is in the vicinity. It sent back some strange noises.
The moon's electric and magnetic waves were recorded by the Waves instrument on 7 June 2021.
When these emissions are shifted into the audio range, there is a wonderfully eerie set of alien shrieks and howls. The audio was unveiled at the fall meeting.
"This soundtrack makes you feel as if you were riding along as Juno sails past the moon for the first time in more than two decades," says physicist Scott Bolton of the Southwest Research Institute.
"If you listen closely, you can hear the abrupt change to higher frequencies around the middle of the recording, which represents entry into a different region in the magnetosphere."
Transposing the data into audio frequencies is not just for fun, it's a different way of accessing and experiencing the data, which can help to pick up on fine details that otherwise might have been overlooked.
The larger of the two planets has a fully differentiated core and a liquid ocean beneath its icy crust that could support life. It is the only one of the Solar System's moons to have a magnetic field.
The revelation that the moon is a million times stronger than the median activity around Jupiter was made by the Galileo mission, which studied Jupiter in the 1990s and early 2000s. It's not clear if that has anything to do with the moon's magnetic field.
At a relative speed of 67,000 kilometers per hour, Juno flew down as low as 1,038 kilometers from the moon's surface. Scientists already have a few ideas about what the new data will reveal.
The University of Iowa physicist and astronomer says that it is possible that the change in the Frequency is due to the passing of the night side to the day side of the moon.
The new discoveries were not limited to the area. The most detailed map of Jupiter's magnetic field has been obtained by Juno. The map took 32 orbits to complete, and has provided new insights into the Great Blue Spot.
The Great Blue Spot, which is being pulled apart by the powerful Jovian winds, is moving eastward at four centimeters per second relative to the rest of the planet's interior, according to the data. This suggests that it completes a lap every 350 years.
Studying a magnetic field allows scientists to understand how a planetary magnetosphere is created. The team's new map shows Jupiter's core has a metallic hydrogen layer around it.
Scientists studied the data to understand turbulence in the Jovian atmosphere. Lia Siegelman of the Scripps Institution of Oceanography tried to connect the dots after seeing the similarity of the turbulence to the turbulence of the phytoplankton in the ocean. She learned that Jupiter's patterns of vortices will stay around for a long time.

The clouds of Jupiter have Plankton in them.
The new photo of Jupiter's tenuous main dust ring was unveiled by the researchers. The arm of the constellation Perseus was captured by the image of the structure from inside the ring.

"We can see the familiar constellations from a half-billion miles away, it is breathtaking," says astronomer, Heidi Becker of NASA's Jet Propulsion Laboratory.
Everything looks the same as when we appreciate them from our backyards. It's an awe-inspiring reminder of how small we are.
The extended mission will continue to provide amazing insights into our Solar System's complex, weird and wonderful colossus, Jupiter.
The results were presented at a meeting.
