NASA announces spooky sounds, recorded by probes in distant satellites

Ganymede - Jupiter's moon is where NASA once doubted the existence of underground seas and life.

On June 7, NASA's Juno probe, which flew near Ganymede - Jupiter's moon and is considered the largest in the solar system - recorded electromagnetic waves generated in the magnetosphere at a distance of more than 628.3 million km from Earth.

When the frequencies of these emissions are shifted into the acoustic range, they create a collection of ghostly howls and screams, like a strange form of alien communication that humans have not yet discovered. known.

This audio was announced at the 2021 American Geophysical Union Meeting.

"The sound makes you feel sick, like you're right next to the Juno when it passed Ganymede the last time," said physicist Scott Bolton of the Southwest Research Institute, principal investigator of the Juno. first in more than two decades. We will analyze it to see what information it contains."

"If we listen closely, we can hear a sudden change in the higher frequencies. This seems to indicate that Juno is moving through another region of the magnetosphere on the Ganymede satellite," Scott reasoned. extra solution.

According to scientists, converting data into audio frequencies is not just for fun. It is also an important way to access and experience different forms of data. From this information, people can figure out small details that might have been overlooked.

"It is possible that the instantaneous frequency change immediately following approach was that of Juno moving from the night side to the day side of Ganymede," said University of Iowa physicist and astrophysicist William Kurth.

This moon is even larger than Mercury, or even the largest moon in the Solar System. It contains a core completely different from the host planet, and may exist a liquid ocean deep beneath the icy crust - possibly life.

According to NASA, Ganymede contains more water than all the oceans on Earth combined. However, because the temperature is so cold, all the water on the surface freezes. Since the water is frozen, there is no evaporation. The next important thing is that Ganymede has its own magnetic field. It is the only moon of the Solar System to possess this.

Structure and size comparison of Ganymede with Earth, Moon

The Galileo spacecraft, which studied Jupiter in the 1990s and early 2000s, also sampled the space around Ganymede, and even discovered that the plasma waves around the moon are 1 million times stronger than those around Ganymede. with average activity at the respective distances around Jupiter.

The data also show that Jupiter's magnetic field has undergone a major shift over the past five years. The team's new map of the planet shows that Jupiter's explosive force is generated by a layer of metallic hydrogen surrounding its core.

The mission with the Juno probe will be extended until June 2025. From now on, it will continue to provide amazing insights into Jupiter - the fifth planet in our Solar System.
