This is what Ganymede, the frozen moon of Jupiter, sounds like | Digital Trends Spanish

Ganymede, the great frozen moon of Jupiter, has sounds of its own, which can be heard for the first time thanks to the work of the Jet Propulsion Laboratory from NASA, which, using the Juno probe, captured the noises from this satellite and turned them into a small, psychedelic audio clip.

These sounds date back to June 7, when Juno approached the body and collected data from Ganymede’s magnetosphere in the form of electrical and radio waves. Then researcher Scott Bolton, one of the scientists working with Juno, transformed this data into audio waves that became the track below.

Bolton explained on the official website of the Jet Propulsion Laboratory that the abrupt changes in the higher frequencies on the track “represent the entrance to a different region of Ganymede’s magnetosphere.” In particular, the sounds were captured while Juno was traveling the satellite at just over 1,000 kilometers (645 miles) and at a speed of 67,000 km / h (or 41,600 mph).

Throughout the solar system there are many satellites, but Ganymede is the only one that has its own magnetic field; at the same time, it does not have any type of atmosphere, so its poles are in a constant plasma bombardment that comes from the magnetosphere of Jupiter.

Juno’s approach to Ganymede in June 2021 also allowed us to get the first images of the north pole of the frozen moon. This mission revealed that the ice growth throughout the satellite is amorphous due to the action of its magnetic field.
