In addition to being the largest planet in the solar system, Jupiter is also known because of its "Great Red Spot" which is the largest and most sustainable storm on the planet. It is 13,000 kilometers in diameter and has been around for 400 years. Now, this unique feature of Jupiter is slowly disappearing. In 1880, the astronomer and artist Etienne Trouvelot sketched Jupiter and the big red spot. The drawing shows its size. According to Glen Orton, a senior scientist at NASA's Jet Propulsion Laboratory, who studies Jupiter long ago, in 1870, the drawings and images of Jupiter's storm looked like a big red sausage. In fact, three piles of earth could fit inside. However, looking now, the storm is now as big as the earth.
"That has just shrunk since," said Orton, adding, "I think that someday it could become the biggest red circle and some scientists think it will not be stable and that it will become GRM : The Great Red Memory. "
The helix formation of the swirling red clouds of the storm had been spotted along its edge. "It's a very unexplored territory," Orton said. "We have never seen it like this before."
The same observations were made in 2017 along the western edge of the storm, but as Orton said, the circumstances were different. "What's unusual now, is there a visibly dark line around the planet for the first time."
With the help of amateur astronomers, they were able to determine undetected things, according to Orton. "The amateur community is the only resource that gets the measurements of Jupiter," he explained. "They are constantly monitoring."
According to CBC, amateur astronomer Christopher Go presented an image of some parts of Jupiter's big red blot on May 27th.
"The oval is … a material that bleeds from the GRS," Go said. "This material will rotate counter clockwise around the genetic resources. the GRS, it should distort the operation of the GRS, which could make it shrink further. "
"At any time, there is someone somewhere in the world who imitates Jupiter," he added. "It really helps us in our long-term understanding of Jupiter."
To date, the NASA Juno is still in orbit around Jupiter and will sew on the GRS by the end of July. In addition, scientists still do not know when the big red dot will separate. As Orton said, the big storm had dropped by about 5 to 15%.
"I would have thought that a propeller would have fallen and that would be the end," concluded Orton. "But there was another storm that happened and another shine came out so time will tell."
