New audio recordings from space are astonishing: Researchers discover similarities between Jupiter and Earth.
Houston – 50 seconds of crunching and hissing: At first, the audio recording, which was recently published on the NASA website, sounds insignificant.
Nevertheless, the audio file was discussed in detail at the American Geophysical Union Fall Meeting in New Orleans in mid-December 2021.
Jupiter: The “Juno” probe collected data on the planet and one of its moons
The reason: It is an audio recording of the magnetic field of “Ganymede” – one of the moons of Jupiter. It comes from records that the “Juno” probe collected during a flyby on June 7, 2021. “Juno” was about 1038 kilometers away from “Ganymed” and thus rarely came close to the Jupiter moon. Data from the magnetosphere of Jupiter and electromagnetic waves were also collected. NASA translated the data into an audio file for the human ear.

Jupiter and Earth: Researchers discover similarities
Scott Bolton, researcher at the Southwest Research Institute in San Antonio, drew attention to a special detail in the recording: if you listen very carefully, an abrupt change to higher frequencies can be heard in the middle of the recording, which means entering another region the magnetosphere of “Ganymede”, so the researcher.

With the data collected by “Juno”, the researchers can now also draw conclusions about the nature of the magnetosphere of Jupiter. Similarities between Jupiter and the earth also appeared: According to this, the atmosphere of Jupiter has similarities with the structures of the eddies and currents in the oceans of the earth.

Jupiter storms have similarities with structures in seas on Earth
Lia Siegelman, who conducts research at the Scripps Institute for Oceanography at the University of California in San Diego, explains it as follows: When she saw the images of the Jupiter cyclones, with all the currents and countercurrents, it reminded her of the vortex movements in the ocean, which she had already researched in her doctoral thesis.

The analysis of all the data that the “Juno” probe was able to collect is far from over. The exploration of Jupiter is still at the very beginning. Although the magnetosphere of Jupiter is larger, the investigations could also help to learn more about the earth, it said in one NASA press release. (df)
The rover “Perseverance”, on the other hand, explores Mars and made a discovery that is reminiscent of its predecessor “Curiosity”.
