The team of the Juno mission laid out the "singing" of plasma waves converted into sound in the environment near Jupiter's moon Europa.
The recording was created from data obtained during the station's recent close flyby the moon.
On September 29, Juno made a very close flyby of Jupiter's icy moon Europa, reaching a minimum distance of approximately 352 kilometers.
That distance almost broke the record set by the Galileo probe.
Despite the rendezvous phase lasted only a few minutes, the station managed to get very detailed images of the satellite's surface and other scientific data.
WAVES TO SOUND
Data on the electric and magnetic fields near the spacecraft during the flight past the satellite were received by the Waves instrument.
The waves should help scientists understand the processes associated with charged particles in the environment around Europa.
The icy satellite is located inside Jupiter's magnetosphere, with which it actively interacts.
The 21-second audio recording was created by scientists by shifting the frequencies of the radiation registered by the device into the audio range.
They recorded plasma waves near Europa in the frequency range from 50 to 150 kilohertz.
Calculations show that the plasma density near the satellite ranged from 60 to 120 electrons per cubic centimeter, with a peak of about 300 particles per cubic centimeter at the moment of closest approach.
These data are similar to those obtained by the Galileo probe between 1996 and 2000.
