[31][32] Storms can last for hours or as long as hundreds of years in the case of the Great Red Spot.[33][34]. The spot is large enough to contain two or three planets the size of Earth. Its dimensions are 24,000–40,000 km east-to-west and 12,000–14,000 km north-to-south. System II is used for latitudes of more than 10°, and was originally based on the average rotation rate of the Great Red Spot of 9h 55m 42s. The volume of Jupiter is 1,317 times the volume of Earth. The latter was observed in 1938–1940, when a few white ovals appeared as a result of instability of the southern temperate zone; they later merged to form Oval BA. [69] However Jupiter has two anticyclones that are somewhat different from all others. [23], Jupiter has many bands of clouds going horizontally across its surface. [41] One year on Jupiter is equal to 11.86 years on Earth. A feature in the South Temperate Belt, Oval BA was first seen in 2000 after the collision of three small white storms, and has intensified since then. Zones, which are colder than belts, correspond to upwellings, while belts mark descending gas. Andres said, "Well, first they said that it was going to cost more to cut the grass around the pole, which is kind of funny. Companies based in Jupiter include G4S Secure Solutions, City Electric Supply, Town Sports International Holdings, and Holtec International. Five years later, the two Voyager spacecraft discovered over 20 new moons. [49] This is called pressure. [49], Circulation in Jupiter's atmosphere is markedly different from that in the atmosphere of Earth. In 2000, the town's population consisted of 20.7% under the age of 18, 5.1% from 18 to 24, 28.8% from 25 to 44, 26.5% from 45 to 64, and 18.9% who were 65 years of age or older.

[3] This is a result of having temperatures and the pressures well above those of the critical points for hydrogen and helium, meaning that there is no sharp boundary between gas and liquid phases. Several similar disturbances in the South Tropical Zone have been recorded since then. Unlike the GRS, they tend to occur in pairs and are always short-lived, lasting a year on average; one was present during the Pioneer 10 encounter. It was the first time people saw a collision between two Solar System objects.[46]. Vortices are thought to be relatively shallow structures with depths not exceeding several hundred kilometers. One called JIMO (Jupiter Icy Moons Orbiter) was cancelled in 2006 because it cost too much money. Jupiter is the largest planet in the Solar System. It was … These bluish-gray regions are usually featureless. [128] The overall trend of the white oval drift rate was deceleration, with a decrease by half between 1940 and 1990. The Great Red Spot (GRS) is a persistent anticyclonic storm, 22° south of Jupiter's equator; observations from Earth establish a minimum storm lifetime of 350 years. Hydrogen becomes a supercritical fluid at a pressure of around 12 bar. Short term observation shows that the southern cyclones move approximately 1.5˚ per perijove, which is small compared to the wind speeds of the cyclones and the turbulent atmosphere of Jupiter. [42] This causes the planet to bulge in the middle. This leads to a uniform temperature in the troposphere. It was no longer present in 1994, although a similar spot had appeared farther to the north. The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. The southern CPCs tend to be bigger with radii ranging from 5,600 km to 7,000 km while northern CPCs range from 4,000 km to 4,600 km.[117]. In 1994, bits of the comet Shoemaker Levy-9 hit Jupiter. The average distance between Jupiter and the Sun is 778 million kilometres. However, unlike in the terrestrial atmosphere, anticyclones predominate over cyclones on Jupiter—more than 90% of vortices larger than 2000 km in diameter are anticyclones. Jupiter's population is served by two public high schools: Jupiter Community High School in Jupiter, and William T. Dwyer High School in Palm Beach Gardens. [55] The other three Galilean moons are Io, Europa and Callisto. [21][22] There are no methane clouds as the temperatures are too high for it to condense. And my pole is a portable pole. As of July 2003, the accepted value for the deuterium abundance is (2.25 ± 0.35) × 10−5,[2] which probably represents the primordial value in the protosolar nebula that gave birth to the Solar System. Jupiter is the third brightest object in the night sky, after the Moon and Venus. [36], The NEB is one of the most active belts on the planet. The Pioneer missions were the first spacecraft to take close up pictures of Jupiter and its moons. Therefore, convection may occur throughout the planet's outer molecular envelope. The southern cyclones don't move around the south pole, but their rotation is more steady around the SPC, which is offset from the pole. The simplest interpretation is that zones are sites of atmospheric upwelling, whereas belts are manifestations of downwelling. [26] The energetic particles coming from Jupiter's magnetosphere create bright auroral ovals, which encircle the poles. [33], The belts and zones that divide Jupiter's atmosphere each have their own names and unique characteristics. Its operational divisions include Road Patrol, Criminal Investigations, Traffic, K-9, Marine, Beach Patrol, Crime Scene Investigation, SWAT and Hostage Negotiation. [47], The fourth season of American Horror Story, American Horror Story: Freak Show, is set in 1952 Jupiter. Therefore, the planet's molecular hydrogen mantle may be divided into cylinders, each cylinder having a circulation independent of the others. They are called the Galilean moons, because Galileo Galilei discovered them. [110] In contrast to vortices, storms are short-lived phenomena; the strongest of them may exist for several months, while the average lifetime is only 3–4 days. [46] Many zones and belts are more transient in nature and are not always visible. [11] The wind speeds at their periphery are about 100 m/s. Although there is more movement among the southern CPCs they tend to retain the pentagonal structure relative to the pole. One group is called the Trojans and the other group is called the Greeks. The difference in the number of cyclones in the north compared to the south is due to the size of the cyclones. [12], The atmosphere of Jupiter is classified into four layers, by increasing altitude: the troposphere, stratosphere, thermosphere and exosphere. Daily thundershowers are common in the hot season, though they are brief. In standard models of the Jovian interior, the mantle comprises the outer 20–30%. [10] Different anticyclones located in one zone tend to merge when they approach each other. This causes it to have no seasons, for example summer or winter. In belts, however, the air descends, warming adiabatically as in a convergence zone on Earth, and white ammonia clouds evaporate, revealing lower, darker clouds. The four largest moons of Jupiter are Io, Europa, Ganymede, and Callisto. The location and width of bands, speed and location of jets on Jupiter are remarkably stable, having changed only slightly between 1980 and 2000. [48], This article is about the town called Jupiter. [45], There are other features on Jupiter that are either temporary or difficult to observe from Earth. As has been known since 1966,[63] Jupiter radiates much more heat than it receives from the Sun. [2] Jupiter's atmosphere is the most comprehensively understood of those of all the gas giants because it was observed directly by the Galileo atmospheric probe when it entered the Jovian atmosphere on December 7, 1995. The closest ring to Jupiter is called the Halo Ring. [95] A feature in the atmosphere of Neptune was also called the Great Dark Spot. [6] The exact nature of chemicals that make Jovian zones and bands so colorful is not known, but they may include complicated compounds of sulfur, phosphorus and carbon. The School District of Palm Beach County provides public education. The EZ varies considerably in coloration, from pale to an ochre, or even coppery hue; it is occasionally divided by an Equatorial Band (EB). [122], A minor mystery concerns a Jovian spot depicted around 1700 on a canvas by Donato Creti, which is exhibited in the Vatican. [99] On February 24, 2006, Filipino amateur astronomer Christopher Go discovered the color change, noting that it had reached the same shade as the GRS. [51] It assumed that the molecular hydrogen mantle is thinner than in all other models; occupying only the outer 10% of Jupiter's radius. Each layer has characteristic temperature gradients. "[103] Some believe that small storms (and their corresponding white spots) on Jupiter turn red when the winds become powerful enough to draw certain gases from deeper within the atmosphere which change color when those gases are exposed to sunlight. [15][16], Jupiter has at least 79 moons. Because of the way they orbit Jupiter, gravity affects three of these moons greatly. The observations were led by Imke de Pater of the University of California, at Berkeley, US. The longest lived STD in recorded history was followed from 1901 until 1939, having been first seen by Percy B. Molesworth on February 28, 1901. [7], The theories regarding the dynamics of the Jovian atmosphere can be broadly divided into two classes: shallow and deep. At the start of 2004, the Great Red Spot had approximately half the longitudinal extent it had a century ago, when it was 40,000 km in diameter. [44] He was the first person to see Jupiter's moons Io, Europa, Ganymede and Callisto. [56] The ultimate result of the process described above is production of large scale elongated structures, which are parallel to the equator. The visibility of GRS is apparently coupled to the appearance of the SEB; when the belt is bright white, the spot tends to be dark, and when it is dark, the spot is usually light. In addition to compact cyclones, Jupiter has several large irregular filamentary patches, which demonstrate cyclonic rotation. [12] It gives off more heat than it gets from the sun. [53] The finite size of the planet means that the cascade can not produce structures larger than some characteristic scale, which for Jupiter is called the Rhines scale. Jupiter has a magnetic field like Earth's but 11 times stronger. [13] Subsequent mapmakers further misunderstood this to be the name of the Roman god also known as Jupiter, and they adopted the more familiar name of Jupiter. [6][38], Early modern astronomers, using small telescopes, recorded the changing appearance of Jupiter's atmosphere. The inner part of the “chaotic” cyclones have small-scale cloud streaks and flecks. [38] Though the southern boundary of the EZ is usually quiescent, observations from the late 19th into the early 20th century show that this pattern was then reversed relative to today.
