The Great Red Spot found on gas giant Jupiter, continues to baffle the scientists. Last year scientists had got to know from the data collected by Juno probe that the storms of Great Red Spot are estimated to be around 187 years old and could remain active after all of us are gone. But, a new study has revealed that the Great Red Spot of Jupiter will die within the next 10 to 20 years.
As per the study, the giant storms of the Great Red Spot are shrinking rapidly and they are going to die in little more than 10 years. Hence, it can be said that we could see the storms of the Great red spot dying in front of us. Glenn Orton, a lead Juno mission team member and planetary scientist at NASA’s Jet Propulsion Laboratory said, “In truth, the GRS (Great Red Spot) has been shrinking for a long time. The GRS will in a decade or two become the GRC (Great Red Circle). Maybe sometime after that the GRM” — the Great Red Memory.”
According to NASA, the Great Red Spot of Jupiter is believed to be hosting one of the biggest storms of our solar system and also these storms bear a very long lifespan. Orton said that not all the storms on Jupiter have a long lifespan and the storms of Great Red Spot are an exceptional case. “Think of the GRS [Great Red Spot] as a spinning wheel that keeps on spinning because it’s caught between two conveyor belts that are moving in opposite directions. The GRS is stable and long-lived because it’s ‘wedged’ between two jet streams that are moving in opposite directions,” Orton explained.
The Great Red Spot was first discovered in the 1800s but scientists say that the GRS existed on Jupiter since the 1600s. When the GRS was first discovered, it was almost four times bigger than our Earth. Again in 1979, when the Voyager 2 zoomed past Jupiter, the GRS was found to be twice the size of our Earth. But when Juno did some close flybys of Jupiter last year, it revealed that Great Red Spot is shrinking and now it is almost 30 percent bigger than our Earth. Also, the Juno data revealed that the jet streams coming out of Jupiter travel speed of a speed of more than 300 mph and these superfast jet streams give more power to the anti-cyclonic storms of the Great Red Spot.
