[EpochTimesDecember192021](Epoch Times reporter Xia Yu comprehensive report) NASA’s Juno space probe has been detecting the solar system’s largest planet Jupiter and its satellites. On Friday (December 17), NASA released a stunning new image of Jupiter taken by Juno and the sound recorded during its flight over Ganymede (Ganymede).
Juno began orbiting Jupiter in July 2016, and recently made the 38th close flyby of the gas giant. Earlier this year, this mission was expanded, and in June, Juno added a mission to fly over Ganymede.
According to NASA’s press release, on Friday, the principal investigator of the Juno at San Antonio Southwest Research Institute, Scott Bolton, said at a briefing at the American Geophysical Union meeting in New Orleans that these overflight data and images Rewriting scientists’ understanding of Jupiter.
Bolton announced for the first time a 50-second audio that was collected from data collected on June 7, 2021 when the Juno flew close to Europa. The audio clips come from electromagnetic waves generated in the planet’s magnetic field. The Juno’s “waveform” instrument receives these signals and encodes them; then, their frequencies are converted into the audio range and made into sound tracks.
Bolton said: “This soundtrack is wild enough to make you feel that when the Juno flew over Ganymede for the first time in more than two decades, you were there. If you listen carefully, you can hear it in the recording. The vicinity of the point suddenly changed to a higher frequency, indicating that it entered a different area in the magnetosphere of Ganymede.”
The Juno team continued to analyze the data of the flight over Ganymede. At that time, Juno was about 645 miles (1,038 kilometers) from the surface of Ganymede, and was speeding at 41,600 miles per hour (67,000 kilometers per hour).
William Kurth, the chief co-investigator of the “Waveform” instrument at the University of Iowa, said in a statement: From night to sun.”
The team also shared stunning new images of Jupiter that resemble an artistic view of Jupiter’s rotating atmosphere. “You can see how beautiful Jupiter is,” Bolton said. “This is really an artist’s palette.”
He said that you will see these incredible swirls and swirling clouds of different colors.
These visually stunning images help scientists better understand Jupiter and its many mysteries. Scientist Lia Siegelman, who works with Juno’s team, is very interested in images of Jupiter’s polar cyclones. She said that she saw the similarities between Jupiter’s atmospheric dynamics and the eddies in the Earth’s oceans.
The Juno data also helped scientists map Jupiter’s magnetic field, including the Great Blue Spot. This area is a magnetic anomaly area located at Jupiter’s equator. The magnetic field map was compiled from data collected from 32 orbits during the Juno mission, providing new insights into the mysterious blue spot.
Since Juno arrived in Jupiter, the team has witnessed changes in Jupiter’s magnetic field. The Great Blue Spot is moving eastward at a speed of 2 inches (5.1 cm) per second, encircling Jupiter in about 350 years.
But the Great Blue Spot is being pulled apart by Jupiter’s jets, giving it a streak appearance. This visual pattern tells scientists that these winds extend down deeper into the planet’s gaseous interior.
The Juno team also released the latest image of Jupiter’s faint dust ring. The brightest strips and nearby dark areas in the image are related to the dust produced by Jupiter’s two small moons, Metis and Adrastea. The image also captured the arm of Perseus.
Heidi Becker, chief co-investigator of the Juno Stellar Reference Unit instrument at NASA’s Jet Propulsion Laboratory in Pasadena, said: “We can gaze at these familiar stars from a spacecraft 500 million miles away. , It’s really breathtaking.”
“Everything looks almost the same as when we admire them in our backyard on Earth. This is an awesome reminder of how small we are and how much we need to explore.” Becker said.
