HOUSTON, KOMPAS.TV – Scientists from the United States Aeronautics and Space Administration (NASA) recently revealed sound recordings captured from Ganymede, Jupiter’s moon.
In June, NASA’s Juno spacecraft flew close to Ganymede.
During its 38th orbit around Jupiter, Juno hovers around Ganymede. With the Waves wave device, Juno recorded electric and magnetic radio waves in Ganymede’s magnetosphere.
NASA scientists then shifted the frequency of the recording to produce a sound track of about 50 seconds long that can be heard by the human ear.
Voice recording from around Ganymede it is said to sound like the high-pitched sound of bells and whistles, like the ones in the movies Star Wars.

“If you listen closely, you can hear a sudden shift to higher frequencies around the center of the recording, indicating the entry of a different region in Ganymede’s magnetosphere,” said Principal Investigator Juno Scott Bolton of the Southwest Research Institute in San Antonio in a statement. as reported from the page Popular Science.
Although analysis of Ganymede’s wave recordings is still ongoing, there are speculations about the origin of the sound.
“Maybe it’s because of the shift from the night side to the day side of Ganymede,” said William Kurth, Bolton’s colleague.
Ganymede is the largest moon in our solar system. Its diameter reaches 41 percent of Earth’s diameter. Ganymede is also the only moon that has its own magnetic field.
