jupiter red spot disappearing

No, A Nurse in Alabama Did Not Die from COVID-19 Vaccine. 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. 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. The Great Red Spot, located in the southern hemisphere, holds title as Jupiter’s largest anticyclone; spanning 12,500 miles wide, it is large enough to swallow Earth two to three times over. Did Olive Garden Revoke Hannity’s Pasta Pass After Capitol Riot? However, by assuming that these observable vortices interact with cloud-free (and unobservable) cyclones, we can explain the abrupt changes. Did David Bowie Say He Supports Fascism and Call Hitler a ‘Rock Star’? 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. It is not known what causes the Great Red Spot's reddish color. 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. This article by Philip Marcus is republished here with permission from The Conversation. In a recent story, Business Insider spoke with Glenn Orton, a lead Juno mission team member and planetary scientist at NASA Jet Propulsion Laboratory (JPL), about the giant storm's fate. 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. 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. My colleagues and I believe it will survive for many more years. 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. 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. Scientists predict Jupiter's Great Red Spot (sometimes called the 'Red Eye') is unraveling and could disappear forever in as little as 20 years. But it won't always be there. Therefore, to understand the health of the spot, planetary scientists need to study the health of its vortex and not its cloud; the cloud’s shrinkage is not a harbinger of death. 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. (Image credit: NASA/SwRI/MSSS/Gerald Eichstädt/Seán Doran/. The Great Red Spot (GRS) is an anti-cyclonic(rotates counter-clockwise) storm that is located 22° south of Jupiter’s equator. For more than a century astronomers documented the motions of cloud-covered anticyclones as they slowly drifted across Jupiter. According to observations taken in the 1800s, the Great Red Spot was once about four times the diameter of Earth.

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. 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. Such mergers are common; Voyager 1 first observed these and they have subsequently been observed every few months. Pictures from space! Jupiter’s Great Red Spot, a gigantic storm more than twice the size of the Earth, has persisted for centuries. However, some astronomers believe, to paraphrase Mark Twain, that the reports of its death are greatly exaggerated, or at least premature. 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. Does Video Show Capitol Police Opening Gates for Rioters? 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.

Jupiter’s Great Red Spot is iconic, the largest and longest-lasting storm ever seen in the solar system. Pieces of the red cloud scatter outward from the stagnation point, appearing as flakes and blades. Anticyclones on this gas giant act similar to cyclones that we experience on Earth, but they have twice the wind speed. The high altitude of the compounds may also contribute to the coloring of the Great Red Spot. There was a problem. 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. © However, some astronomers believe, to … 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.

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. 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. "Maybe sometime after that the GRM," by which he means the "Great Red Memory.". The Great Red Spot is one of the most recognizable features in Jupiter’s atmosphere and the entire Solar System. The massive storm — larger than Earth itself — was first spotted in 1830, and observations from the 1600s also revealed a giant spot on Jupiter's surface that may have been the same storm system. 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.

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. Amy discusses new research that might hold the key. NASA revealed today that the iconic Great Red Spot on Jupiter has shrunk to its smallest size ever – and astronomers have no idea why. We discovered that the area of the spot cloud is larger than its underlying vortex, the swirling gas that defines it. A famed medieval transcript described the Earth’s lunar companion as “wholly gone.”. It rotates counterclockwise, the opposite direction of hurricanes on Earth. Typically, small anticyclones are not “digested” immediately, but produce lumps on the spot’s boundary that orbit around it, slowly migrating into the center.

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.
