The Great Red Spot  could disappear in the next 2 decades Jupiter's Great Red Spot is an anticyclone that swirls around a center of high atmospheric pressure. Jupiter’s Great Red Spot may be dying, and could disappear within our lifetimes . And if you have a news tip, correction or comment, let us know at: community@space.com. The Great Red Spot has been there for a while, but scientists still struggle identify what causes its swirl of reddish hues. In 1979, when two Voyager spacecraft flew close by Jupiter, images showed that the spot was a red cloud that rotated as part of a huge vortex several times larger than the Earth. In 1979, when two Voyager spacecraft flew close by Jupiter, images showed that the spot was a red cloud that rotated as part of a huge vortex several times larger than the Earth. However, anticyclones repel cyclones. However, by assuming that these observable vortices interact with cloud-free (and unobservable) cyclones, we can explain the abrupt changes. An illustration comparing the size of Jupiter's Great Red Spot to that of Earth. That works out to more than 35,000 miles — four times the diameter of Earth. This material may not be reproduced without permission. The beautiful structure of this extraordinary atmospheric intrigued me since my career was evolving from astrophysics to fluid dynamics – the study of how liquids and gases move. July 26, 2019 By Joe Bergeron Filed Under: Solar System. You will receive a verification email shortly. 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. Jupiter's emblematic feature might disappear in a decade or two. 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. Scientists had even make some assumptions that it might disappear entirely over two decades. Any cloud or undigested lump on the spot that encounters a stagnation point will similarly shatter and flake away in opposite directions. The high altitude of the compounds may also contribute to the coloring of the Great Red Spot. In the last 10 years, but in the last five months in particular, the press has reported dire warnings that the Great Red Spot of Jupiter is dying. Unidentified Object Falls From Sky in India 00:36.

Over the past couple decades, Jupiter's Great Red Spot has gotten visibly smaller. Data on Jupiter's crimson-colored spot reveals that this shrinking is still occurring. Jupiter’s Great Red Spot: A Swirling Mystery For more than a century astronomers documented the motions of cloud-covered anticyclones as they slowly drifted across Jupiter. Will the WhatsApp Message ‘Argentina Is Doing It’ Hack My Phone? The Great Red Spot is one of the most recognizable features in Jupiter’s atmosphere and the entire Solar System. February … When a large anticyclone and smaller cyclone approach each other before repelling, they create a “stagnation” point near the boundary of the anticyclone where the local winds abruptly change direction, going off approximately perpendicular to their original directions. Did ‘The Simpsons’ Predict Pro-Trump Horned Rioter Jake Angeli? Scientists predict Jupiter's Great Red Spot (sometimes called the 'Red Eye') is unraveling and could disappear forever in as little as 20 years. Hypotheses supported by laboratory experiments suppose that the color may be caused by chemical products created from the solar ultraviolet irradiation of ammonium hydrosulfide and the organic compound acetylene, which produces a reddish material—likely complex organic compounds called tholins. The scientist even warned “nothing lasts forever”as the … Jupiter's Great Red Spot Could Disappear Soon 00:37. It rotates counterclockwise, the opposite direction of hurricanes on Earth. Read the original article. Does Video Show Capitol Police Opening Gates for Rioters? Were Pro-Trump Mobs Storming the Capitol on Jan. 6 Actually Antifa? There was a problem.

Changes in their speeds were often abrupt and seemed to occur for no reason. But it won't always be there. However, some astronomers believe, to … Did US Capitol Police Officer Take a Selfie With Rioter? A (false color) series of images capturing the repeated flaking of red clouds from the GRS in the Spring of 2019. This content is shared here because the topic may interest Snopes readers; it does not, however, represent the work of Snopes fact-checkers or editors. Jupiter’s Great Red Spot is iconic, the largest and longest-lasting storm ever seen in the solar system. Original article on Space.com. In the late 1800s, the storm was perhaps as wide as 30 degrees longitude, Orton said. Please refresh the page and try again. Space Chat with Space.com: Tune in Fridays for science, space and more!

Did Democratic Congressman Add ‘A-Woman’ to Opening Prayer? The iconic Great Red Spot of Jupiter may disappear in the next 20 years, according to a researcher at NASA's Jet Propulsion Laboratory (JPL) in California. 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. In spring 2019, when the “flaking” was observed, the Great Red Spot was also observed to merge with a series of small clouds (likely small anticyclones) on its northwest side. 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. Watch: Strong Winds Send Canopy Flying 00:34. The numerical calculations of my Berkeley research group show that the recent observations of cloud shedding can be explained by the collision of undigested red clouds at the edge of the Great Red Spot with stagnation points produced during a close encounter with a cyclone. NASA revealed today that the iconic Great Red Spot on Jupiter has shrunk to its smallest size ever – and astronomers have no idea why. © By Mike Wehner @MikeWehner. Join our Space Forums to keep talking space on the latest missions, night sky and more! Next Up. Jupiter’s Great Red Spot, a gigantic storm more than twice the size of the Earth, has persisted for centuries. Some, like this spot, are anticyclones that rotate in the opposite direction of the planet’s spin; others are cyclones that rotate in the same direction as the planet’s spin. Thank you for signing up to Space. Did the Moon Briefly ‘Disappear’ 1,000 Years Ago? Such mergers are common; Voyager 1 first observed these and they have subsequently been observed every few months. We discovered that the area of the spot cloud is larger than its underlying vortex, the swirling gas that defines it. Persisted for centuries, the spot could disappear forever in as little as 20 years, predicted scientists. It has been around for at least hundreds of years, but is it now nearing its end? This article by Philip Marcus is republished here with permission from The Conversation. While the reddish-hued storm is massive, it was once much larger. New NASA imagery revealed that the Spot shrunk by 150 miles in the last year. Anticyclones merge with each other.

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. Some reports from May, however, started detailing that it was beginning to diminish. Image credit: Anthony Wesley. Neither the mergers that created the lumps nor the close encounters with cyclones are unusual by themselves, but it is not that common for them to occur at the same time. Jupiter’s atmosphere contains vortices besides the Great Red Spot, some of which are useful for monitoring its health. How do we know that Jovian cyclones exist when clouds are not visible? One of the solar system’s most iconic landmarks is about to vanish. 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). The Great Red Spot has been a fixture of Jupiter’s cloudy visage for centuries and is among the most recognizable features in the solar system. 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. According to observations taken in the 1800s, the Great Red Spot was once about four times the diameter of Earth. Based on the spot’s interactions with other vortices my Berkeley group found there is no evidence that that vortex itself has changed its size or intensity. However, some astronomers believe, to paraphrase Mark Twain, that the reports of its death are greatly exaggerated, or at least premature. Jupiter's Great Red Spot is dying.
