Scientists like to ​​transpose data into audio frequencies as a way of accessing and experiencing the data.

Doing so can often help them pick up on fine details that otherwise might have been overlooked.

NASA has been recording the mysterious “sounds” of the Solar System with a range of probes, including the Voyager spacecraft, as well as for its planetary missions.

While they are still decoding what the new data means, scientists have a few ideas.

Physicist and astronomer William Kurth of the University of Iowa said: “It is possible the change in the frequency shortly after the closest approach is due to passing from the nightside to the dayside of Ganymede.”

NASA has always been fascinated with Ganymede,

It is the largest moon in our solar system, bigger than the planet Mercury and the dwarf planet Pluto.

NASA’s Hubble Space Telescope has found the best evidence yet for an underground saltwater ocean on Ganymede.

They believe that the ocean has more water than all the water on Earth’s surface.

Ganymede’s ocean is estimated to be 60 miles (100 kilometers) thick – 10 times deeper than Earth’s ocean – and is thought to be buried under a 95-mile- (150-kilometer-) thick crust of mostly ice.

NASA says: “Identifying liquid water is crucial in the search for habitable worlds beyond Earth and in the search for life as we know it.”

Ganymede is the only moon known to have its own magnetic field, which scientists discovered through NASA’s Galileo spacecraft in 1996.

The magnetic field causes auroras, which are ribbons of glowing, hot, electrified gas, in regions circling the north and south poles of the moon.

Ganymede was first discovered by Italian astronomer Galileo Galilei in 1610.

The discovery, along with his finding of three other large moons around Jupiter, was the first time a moon was discovered orbiting a planet other than Earth.
