This strange and somewhat creepy sound represents a drop in the plasma frequency, using data from the Jupiter spacecraft that periodically passed by Jupiter’s icy moon Earopa on September 29 at about 350 degrees. km with speeds up to 23.6 km/s, Space hugs October 27.
Video: The sound comes from the moon Ganymede.
In this video, plasma waves are measured by the Waves instrument on the Juno spacecraft and converted to a frequency range that can be heard by humans. The white cauldron is moved on the spectrophotometer, an intuitive way to measure the signal strength of the paper, we can detect the frequency conversion of the plasma wave near Eropa and the plasma density.
Electronic video was collected in approximately 1.5 hours during the event. The sheet is displayed under the horizontal axis on the International Consortium (uTC) – a careful, worldwide, global summary of the table.

During that period, the chromaticity is measured in terms of electric field magnitude and frequency. Whichu is simply warm to the side of the single magnitude. The blobs are emission at the characteristic frequency of the repulsive magnetic plasma. These emissions tell us that the density of the plasma near Eoropa ranges from about 60 to 120 electrons/cm3, with a very short peak of nearly 300 electrons/cm3 right at the point where Jono approaches Earopa near Earth at 9h36.
The Waves instrument is designed to help readers understand the interactions between the planet’s planet, Jupiter’s magnetosphere, and magnetosphere, along with its polar poles. The device can generate electric field of radio emission from 50 z to 40,000,000 z and magnetic field from 50 z to 20,000 z
Knowing the plasma density near Eoropa is crucial for these icy moons to interact with Jupiter’s magnetosphere. Jupiter’s magnetic field - the largest in the Solar System - traps plasma that fills the space of Eoropa. While Jupiter’s moon moves in orbit, the magnetic field changes. The astronomical docks to Eoropa generate its own magnetic field, which in turn could provide a clue to the structure of the moon’s interior.

The Juno spacecraft – which has been in orbit around Jupiter since July 4, 2016 – is the first eight-pointed device that has flown below the moon’s dense clouds to answer questions about the name. The giant sign is also the origin of the Solar System. Jano’s extended mission begins in August 2021 and will continue to investigate Jupiter until September 2025.
