Since entering Jupiter’s orbit in 2016, Juno spacecraft of NASA Has been hard in work Unveiled many mysteries The largest planet of our solar system. And its latest discovery can be one of the most complicated yet: a completely new type of plasma wave near Jupiter’s poles.
In a paper published on Wednesday Physical review paperAstronomers have described an unusual pattern of plasma waves in the magnetosphere of Jupiter – a magnetic “bubble” is molding the planet from external radiation. The extraordinary powerful magnetic field of Jupiter forces two very different types of plasma to go into the tendem, making a unique flow of particles and atoms charged in its polar regions.
Plasma is an important force in shaping the turbulent atmosphere of Jupiter. For example, researchers believe that new comments will further enhance our understanding of magnetic properties of distant exoplanets not only the events of Jupiter.
For the study, researchers analyzed the behavior of plasma waves in the magnetosphere of the jupiter, with highly magnetic, low -density plasma. A cooperation between the team, the University of Minnesota, the University of Iowa and the South West Research Institute, Texas’s researchers, Texas, Alphawen found an unexpected oscillation between waves and langamuir waves, which reflects the movement of plasma atoms and the movement of electrons in plasma respectively.
Electrons are much lighter than charged atoms, which means, usually, two waves wave very different frequencies – which was not clearly a case for Jupiter’s magnetosphere, inspires researchers to look closely. The upcoming investigation never saw the plasma oscillation near Jupiter’s pole.
“Plasma properties are really unusual, not found in our solar system before and anywhere else,” John Leaf Georgenson, a planetary scientist of Denmark’s Technical University who was not involved in the new work, said, ” New scientist,
Unlike the Earth’s andorus, which are caused by solar storms, Jupiter’s Aurorus – a barrage of a barrage, superfast particle Hundreds of times more energetic Compared to Earth and sometimes it emerges as a product of its powerful magnetic field. According to study authors, how can there be better information for such events for future missions in search of foreign lives on exoplanets.
Astronomers wrote in paper, “Such conditions do not occur on earth (on) on Earth, it is possible that they are applied to the polar regions of other giant planets and in potentially strong exoplanets or stars”.
Scott Bolton, the chief investigator of Juno at NASA, said, “Jupiter is the Roseta Stone of our solar system.” Introductory page For spacecraft. “Juno is going there as our messenger – to explain what Jupiter has to say.”
Initially, NASA expected to end the mission of Juno in 2017, when he would deliberately run the spacecraft in Jupiter’s atmosphere, a decision that follows NASA’s planetary safety requirements. But Juno’s flight road evolved over time, and NASA concluded that spacecraft There is no threat to Jupiter’s moon now. As a result, the agency authorized the extension for the mission.
It is being said, scientists believe that by September this year, the class of Juno will naturally be lowered, and will be provoked by Jupiter’s atmosphere. However, it does not eliminate Jupiter’s discovery of humanity in any way; Europea clipper In 2030, Europea has been slapped to reach the Moon of Jupiter (last time we investigated, It traveled to some scenic spots near MarsOf course, even after consuming Jupiter Juno, scientists will still have the weight of invaluable data from the spacecraft that they will continue to analyze carefully for the coming years.
