It can be difficult to imagine Jupiter's icy moon and the largest moon in our Solar System. I am still at a point where I am convinced that it is a big moon. Scientists are still working on understanding it. You can now listen to what the moon sounds like in space if you want to learn more about it.
You can listen to the 50-second audio track below, created with data from the close flyby of Ganymede, that was published by NASA on Friday. The data for the recording was gathered with the Waves instrument, which measures electric and magnetic waves produced in Jupiter's magnetosphere. The audio track was made by shifting the frequencies of the emissions into the audio range.
The recording was presented at the fall meeting of the American Geophysical Union. The goal of the mission is to understand how giant planets form and the role they played in the creation of the Solar System.
According to a NASA news article, the soundtrack is wild enough to make you feel as if you were riding along on the journey to the moon. You can hear the change to higher frequencies around the middle of the recording, which is a sign of entry into a different region in the magnetosphere.
G/O Media might get a commission.
The closest a space craft has ever gotten to the largest moon in the Solar System was in 2000 when the Galileo mission approached.
While traveling at a speed of 41,600 mph, the spacecraft was able to get close to the surface of Ganymede.
