However, anticyclones repel cyclones. Jupiter's south equatorial belt, now missing, crosses the Great Red Spot in a picture taken in 2000 by NASA's Cassini orbiter. By analyzing the cloud images with computer models that incorporate the physics of how fluids move, my research group at Berkeley was able to determine the area of the spot. Indeed, Jupiter's atmosphere is a mysterious place which would benefit from exploration. However, some astronomers believe, to … Visit our corporate site. According to Orton, the storm's vortex has maintained strength because of Jupiter's 300-400 mph (483-640 km/h) jetstreams, but like any storm, it won't go on forever. The flake then breaks off from the GRS, but a new flake starts to detach in the fifth image. Follow Doris Elin Salazar on Twitter @salazar_elin. The Great Red Spot is a huge storm in Jupiter's atmosphere and was first spotted 300 years ago.. It is difficult to determine the relationship between the cloud’s size and the vortex’s size or even how Jovian clouds form and dissipate. Over the past week, amateur astronomers around the world have seen some unusual activity around the solar system's largest and longest-lasting storm. However, by assuming that these observable vortices interact with cloud-free (and unobservable) cyclones, we can explain the abrupt changes. The Great Red Spot (GRS) is an anti-cyclonic(rotates counter-clockwise) storm that is located 22° south of Jupiter’s equator. Were Pro-Trump Mobs Storming the Capitol on Jan. 6 Actually Antifa? New York, "In truth, the GRS has been shrinking for a long time," Orton told Business Insider. I believe that the shedding of clouds from the spot as “flakes” and “blades” observed in 2019 was due to two simultaneous events: undigested lumps of merged anticyclones traveling along the spot’s boundary and a close encounter with one or more “unobservable” cyclones. Some reports from May, however, started detailing that it was beginning to diminish. I have been intrigued by the Great Red Spot since 1979, when I viewed the Voyager images only days after NASA processed them. Jupiter’s Great Red Spot Isn’t Disappearing. Watch: Strong Winds Send Canopy Flying 00:34. The question then becomes: Does a decrease in the area of the cloud mean that the vortex itself is shrinking? Pictures from space! No, A Nurse in Alabama Did Not Die from COVID-19 Vaccine. Persisted for centuries, the spot could disappear forever in as little as 20 years, predicted scientists. Recent images showed more cloud shrinkage, leading to headlines that the spot could die within 20 years. It has been around for at least hundreds of years, but is it now nearing its end? The Great Red Spot has been there for a while, but scientists still struggle identify what causes its swirl of reddish hues. The Disappearing Great Red Spot. Concerns for the Great Red Spot’s “health” arose when astronomers realized that the cloud’s area in 1979 was only half of its size in the 1800s, as determined from old photographic plates. Jupiter’s Great Red Spot might disappear in the next 20 years If you’ve seen any picture of Jupiter you’ve no doubt noticed the massive red oval-shaped spot on its surface.

(Image: © NASA/JPL/Björn Jónsson/Seán Doran/. Read the original article. The Great Red Spot (GRS) is a giant anticyclonic storm rotating counterclockwise in the southern hemisphere of the planet (22 degrees south of Jupiter’s equator). Jupiter’s Great Red Spot, a gigantic storm more than twice the size of the Earth, has persisted for centuries. Think of two fire hoses aimed at each other so that their streams of water collide – the streams momentarily halt at the point of impact (the stagnation point) and then scatter outward. However, some astronomers believe, to … The scientist even warned “nothing lasts forever”as the … Amy discusses new research that might hold the key. As of April 3, 2017, the GRS spanned the width of 10,159 miles (16,350 kilometers), less than 1.3 times Earth's diameter.The longest storm on Earth lasted 31 days, but Jupiter can sustain longer storms because the gas planet has tens of thousands of miles of atmosphere, and spins much faster than Earth. How do we know that Jovian cyclones exist when clouds are not visible? That works out to more than 35,000 miles — four times the diameter of Earth. New dissipative activity is shrinking and may be destabilizing this famous feature in Jupiter’s atmosphere. Did the Moon Briefly ‘Disappear’ 1,000 Years Ago? The high altitude of the compounds may also contribute to the coloring of the Great Red Spot. Join our Space Forums to keep talking space on the latest missions, night sky and more! When the nuclear-powered spacecraft Voyager 2 flew by Jupiter in 1979, however, the storm had shrunk to a bit more twice the width of our own planet. By Mike Wehner @MikeWehner. Did ‘The Simpsons’ Predict Pro-Trump Horned Rioter Jake Angeli? A (false color) series of images capturing the repeated flaking of red clouds from the GRS in the Spring of 2019. Anticyclones on this gas giant act similar to cyclones that we experience on Earth, but they have twice the wind speed. Will the WhatsApp Message ‘Argentina Is Doing It’ Hack My Phone? One of the solar system’s most iconic landmarks is about to vanish. Jupiter and the cyclonic feature known as the Great Red Spot, lower right, in 2019. Does Video Show Capitol Police Opening Gates for Rioters? Next Up. Original article on Space.com. Follow us @Spacedotcom, Facebook and Google+. New NASA imagery revealed that the Spot shrunk by 150 miles in the last year. Future US, Inc. 11 West 42nd Street, 15th Floor, Measuring in at 10,159 miles (16,350 kilometers) in width (as of April 3, 2017) Jupiter’s Great Red … This article is republished from The Conversation under a Creative Commons license. Anticyclones appear as bright clouds and so are easily detectable, but cyclones (except at the poles) often have filamentary clouds or no clouds at all.
