Ganymede, the moon of Jupiter and also the largest natural satellite in our Solar System, is surely an incredible place. Ganymede is even larger than Mercury, the first planet from the Sun.
NASA has brought back some truly out-of-this-world sounds recorded at Ganymede that have the potential of raising the hair from your back. The sounds seem as they were taken straight from a horror movie where Earth is invaded by Artificial Intelligent robots that consider humans to be totally useless.
Recording Ganymede’s electromagnetic waves
The sounds of electromagnetic waves from Ganymede were recorded by NASA by using the Wave instrument mounted on the Juno probe back in June.
Feel free to listen, but don’t forget to have your courage alongside you:
Scott Bolton, a physicist of the Southwest Research Institute and also principal investigator of Juno, declared as quoted by the Jet Propulsion Laboratory’s website:
This soundtrack is just wild enough to make you feel as if you were riding along as Juno sails past Ganymede for the first time in more than two decades,
If you listen closely, you can hear the abrupt change to higher frequencies around the midpoint of the recording, which represents entry into a different region in Ganymede’s magnetosphere.
It may not be too surprising that Ganymede is the only discovered moon in our Solar System that possesses a substantial magnetosphere. Scientists suspect that the moon of Jupiter also has an ocean hidden under the surface, and the core is composed of liquid iron and nickel.
Luckily for all of us, the Universe never seems to run out of exciting stuff to show us. While this may be frustrating for those willing to discover absolutely everything, the unknown is actually part of the beauty of science itself.
