SoI have strange storms Jupiter Discovered in 2017 by a NASA spacecraft Particularly interesting to Scientists. new search try to find out How The nine Tornadoes Still spinning at Jupiter’s north pole Very orderly.

Jupiter Creator big red spot It is actually a mass of swirling storm clouds called an anticyclone, and He. She’s Just one of many storms on gas giant. At Jupiter’s north pole, there is a family of nine hurricanes – one large storm surrounded by eight smaller ones – first observed in 2017 by NASA’s Juno spacecraft, which orbits the planet. published a study in natural astronomy to examine Why is this composition left? stable for the past few years, if not long before it was discovered.

“Since 2017, the Juno spacecraft has observed a cyclone at Jupiter’s north pole surrounded by eight smaller cyclones arranged in a polygonal pattern,” the study authors wrote.. “It is not clear why this formation is stable or how to maintain it.”

The south pole of Jupiter has a similar composition, with the exception of five storms that make up the pentagon, Unlike the eight at the North Pole that form an octagon. Researchers refer to engineering storm systems in the North and South Pole as “polygonsand writing: “The individual polygons and vortices that compose them have been stable for 4 years since Juno discovered them. Polygonal patterns rotate slowly or not at all.”

The researchers used a series of images from Juno’s Jovian Infrared Auroral Mapper, or JIRAM, To study the behavior of these storms. They found that “anti-vortex ring” surround Center The storm, rotating in the opposite direction as the main direction tornado. The researchers argue that this loop could stabilize the system.
