Otherworldly sounds: Hear what Juno picked up while on a flight around Ganymede

The US space agency’s mission, Juno, flew near Jupiter’s moon Ganymede a few months ago. The portal wrote that the result was a wonderful recording that brings us closer to the sounds of this world Scitech Daily.

The recording is 50 seconds long and was created from data collected by the Juno spacecraft during the flight. The scientific wave instrument is capable of picking up the electrical and magnetic radio waves that are generated in Jupiter’s magnetosphere. The researchers then relayed the data to the point where the human ear could hear.

“The record is really cool and brutal enough to make you feel like that You are right next to the Juno probe. If you are listening, you may notice a shift to higher frequencies in the middle of the recording. This means Juno has entered another part of the magnetosphere of Ganymede, Scott Bolton, who is part of the Juno mission.

The Juno spacecraft flew over the moon on June 7 this year, the 34th flight around the gas giant. During the flight, the probe approached the distance A thousand kilometers from the surface of the moon And it was moving at a speed of 67,000 km / h. Not only did Juno get a great record, but it also got enough data to allow scientists on Earth to create the most detailed map of Jupiter’s magnetosphere to date.

The map includes data from 32 flights around the gas giant and provides scientists with more information about the mystery of the largest planet in the solar system. The mystery is the so-called Great Blue Spot, a magnetic anomaly in the region of Jupiter’s equator. Mission data Juno suggests that changes in the gas giant’s magnetic field occurred during the five years that the probe was in orbit around the planet.

What is happening in the atmosphere of Jupiter?

At the same time, it turned out that the large blue spot was moving east at a speed of 4 cm / s. If the spot maintains its speed, it will orbit the planet in 350 years.

The researchers also obtained information about another large spot – the Great Red Spot. It is a huge storm that has lasted for hundreds of years. It is moving west at a much faster speed. The Great Red Spot will orbit the planet in four and a half years.

New information provided by Juno helps scientists compare the magnetic field of Jupiter and our Earth. According to the available information, the effect of the dynamo, which helps the planets to generate a magnetic field, Formed on Jupiter in a layer of metallic hydrogen. It is located below the layer in which helium rains.

Scientists also note that beliefs in Jupiter’s atmosphere are similar to beliefs that arise in our oceans.

“When I saw the turbulence on Jupiter, I immediately felt the turbulence that can be observed in our oceans. These similarities can be seen especially in the high-resolution images,” said Leah Siegelman, of the University of California.

Jupiter is much bigger than Earth, but we still have it process study, that occur in its atmosphere, help to understand the processes occurring on our planet.
