172.Phalanx.
The phalanx (Ancient Greek: ??????, Modern Greek: ???????, ph?langa; plural phalanxes or phalanges; Ancient and Modern Greek: ????????, ph?langes) is a rectangular mass military formation, usually composed entirely of heavy infantry armed with spears, pikes, sarissas, or similar weapons. The term is particularly (and originally) used to describe the use of this formation in Ancient Greek warfare, although the ancient Greek writers used it to also describe any massed infantry formation, regardless of its equipment, as does Arrian in his Array against the Alans when he refers to his legions. In Greek texts, the phalanx may be deployed for battle, on the march, even camped, thus describing the mass of infantry or cavalry that would deploy in line during battle. They marched forward as one entity. The word phalanx is derived from the Greek word phalangos, meaning finger.
The term itself, as used today, does not refer to a distinctive military unit or division (e.g., the Roman legion or the contemporary Western-type battalion) but to the general formation of an army's troops. Thus a phalanx does not have a standard combat strength or composition but includes the total number of infantry, which is or will be deployed in action in a single phalanx formation.
Many spear-armed troops historically fought in what might be termed phalanx-like formations. The word has come into use in common English to describe "a group of people standing, or moving forward closely together"; c.f. "a phalanx of police".
The earliest known depiction of a phalanx-like formation occurs in a Sumerian stele from the 25th century BC. Here the troops seem to have been equipped with spears, helmets, and large shields covering the whole body. Ancient Egyptian infantry were known to have employed similar formations. The first usage of the term phalanx comes from Homer's "(??????)", used to describe hoplites fighting in an organized battle line. Homer used the term to differentiate the formation-based combat from the individual duels so often found in his poems.
The hoplite phalanx of the Archaic and Classical periods in Greece (ca. 750?350 BC) was a formation in which the hoplites would line up in ranks in close order. The hoplites would lock their shields together, and the first few ranks of soldiers would project their spears out over the first rank of shields. The phalanx therefore presented a shield wall and a mass of spear points to the enemy, making frontal assaults against it very difficult. It also allowed a higher proportion of the soldiers to be actively engaged in combat at a given time (rather than just those in the front rank).
Battles between two phalanxes usually took place in open, flat plains where it was easier to advance and stay in formation. Rough terrain or hilly regions would have made it difficult to maintain a steady line and would have defeated the purpose of employing the use of a phalanx. As a result, battles between Greek city-states would not take place in any possible location, nor would they be limited to sometimes obvious strategic points. Rather, many times, the two opposing sides would find the most suitable piece of land where the conflict could be settled. Mostly the battle ended with one of the two fighting sides fleeing to safety.
The phalanx usually advanced at a walking pace, although it is possible that they picked up speed during the last several yards. One of the main reasons for this slow approach was to maintain formation. If the phalanx lost its shape as it approached the enemy it would be rendered useless. If the hoplites of the phalanx were to pick up speed toward the latter part of the advance it would have been for the purpose of gaining momentum against the enemy in the initial collision. Herodotus states, of the Greeks at the Battle of Marathon, that "They were the first Greeks we know of to charge their enemy at a run". Many historians believe that this innovation was precipitated by their desire to minimize their losses from Persian archery. The opposing sides would collide, possibly shivering many of the spears of the row in front and killing the front part of the enemy army due to the bone breaking collision of the start of the battle. The battle would then rely on the valour of the men in the front line; whilst those in the rear maintained forward pressure on the front ranks with their shields. When in combat, the whole formation would consistently press forward trying to break the enemy formation; thus when two phalanx formations engaged, the struggle essentially became a pushing match.
This "physical pushing match" theory is the most widely accepted interpretation of the ancient sources. Historians such as Victor Davis Hanson point out that it is difficult to account for exceptionally deep phalanx formations unless they were necessary to facilitate the physical pushing depicted by this theory, as those behind the first two ranks could not take part in the actual spear thrusting.
Yet it should be noted that no Greek art ever depicts anything like a phalanx pushing match and this hypothesis is a product of educated speculation rather than explicit testimony from contemporary sources. The Greek term for "push" was used in the same metaphorical manner as the English word is (for example it was also used to describe the process of rhetorical arguments) and so cannot be said to necessarily describe a literal, physical, push of the enemy, although it is possible that it did. In short, the hypothesis is far from being academically resolved.
For instance, if Othismos were to accurately describe a physical pushing match, it would be logical to state that the deeper phalanx would always win an engagement, since the physical strength of individuals would not compensate for even one additional rank on the enemy side. However, there are numerous examples of shallow phalanxes holding off an opponent. For instance, at Delium in 424 the Athenian left flank, a formation eight men deep, held off a formation of Thebans twenty-five deep without immediate collapse. It is difficult with the physical pushing model to imagine eight men withstanding the pushing force of twenty-five opponents for a matter of seconds, let alone half the battle.
Such arguments have led to a wave of counter-criticism to physical shoving theorists. Adrian Goldsworthy, in his article "The Othismos, Myths and Heresies: The nature of Hoplite Battle" argues that the physical pushing match model does not fit with the average casualty figures of hoplite warfare, nor the practical realities of moving large formations of men in battle. This debate has yet to be resolved amongst scholars.
Practical difficulties with this theory also include the fact that in a shoving match, an 8-foot spear is too long to fight effectively or even parry attacks. Spears enable a formation of men to keep their enemies at a distance, parry attacks aimed at them and their comrades, and give the necessary reach to strike multiple men in the opposite formation. A pushing match would put enemies so close together that a quick stabbing with a knife would kill the front row almost instantly. The crush of men would also prevent the formation from withdrawing or retreating, which would result in much higher casualties than is recorded. The speed at which this would occur would also end the battle very quickly, instead of prolonged battles lasting hours.
Each individual hoplite carried his shield on the left arm, protecting not only himself but the soldier to the left. This meant that the men at the extreme right of the phalanx were only half-protected. In battle, opposing phalanxes would exploit this weakness by attempting to overlap the enemy's right flank. It also meant that, in battle, a phalanx would tend to drift to the right (as hoplites sought to remain behind the shield of their neighbour). The most experienced hoplites were often placed on the right side of the phalanx, to avoid these problems. Some groups, such as the Spartans at Nemea, tried to use this phenomenon to their advantage. In this case the phalanx would sacrifice its left side, which typically consisted of allied troops, in an effort to overtake the enemy from the flank. It is unlikely that this strategy worked very often, as it is not mentioned frequently in ancient Greek literature.
There was a leader in each row of a phalanx, and a rear rank officer, the ouragos (meaning tail-leader), who kept order in the rear. The phalanx is thus an example of a military formation in which the individualistic elements of battle were suppressed for the good of the whole. The hoplites had to trust their neighbours to protect them, and be willing to protect their neighbours; a phalanx was thus only as strong as its weakest elements. The effectiveness of the phalanx therefore depended upon how well the hoplites could maintain this formation while in combat, and how well they could stand their ground, especially when engaged against another phalanx. For this reason, the formation was deliberately organized to group friends and family closely together, thus providing a psychological incentive to support one's fellows, and a disincentive through shame to panic or attempt to flee. The more disciplined and courageous the army the more likely it was to win ? often engagements between the various city-states of Greece would be resolved by one side fleeing before the battle. The Greek word dynamis, the "will to fight", expresses the drive that kept hoplites in formation.
"Now of those, who dare, abiding one beside another, to advance to the close fray, and the foremost champions, fewer die, and they save the people in the rear; but in men that fear, all excellence is lost. No one could ever in words go through those several ills, which befall a man, if he has been actuated by cowardice. For 'tis grievous to wound in the rear the back of a flying man in hostile war. Shameful too is a corpse lying low in the dust, wounded behind in the back by the point of a spear." Tyrtaeus: The War Songs Of Tyrtaeus.
The phalanx of the Ancient Macedonian kingdom and the later Hellenistic successor states was a development of the hoplite phalanx. The 'phalangites' were armed with much longer spears (the sarissa; see below), and less heavily armoured. Since the sarissa was wielded two-handed, phalangites carried much smaller shields that were strapped to their arms. Therefore, although a Macedonian phalanx would have formed up in a similar manner to the hoplite phalanx, it possessed very different tactical properties. With the extra spear length, up to five rows of phalangites could project their weapon beyond the front rank?keeping the enemy troops at a greater distance. The Macedonian phalanx was much less able to form a shield wall, but the lengthened spears would have compensated for this. Such a phalanx formation also reduces the likelihood that battles would degenerate into a pushing match.

Hoplite armament.
Each hoplite provided his own equipment. The primary hoplite weapon was a spear around 2.4 meters in length called a dory. Although accounts of its length vary, it is usually now believed to have been seven to nine feet long (~2.1?2.7 m). It was held one-handed, with the other hand holding the hoplite's shield (called Aspis). The spearhead was usually a curved leaf shape, while the rear of the spear had a spike called a sauroter ('lizard-killer') which was used to stand the spear in the ground (hence the name). It was also used as a secondary weapon if the main shaft snapped or to kill enemies lying on the ground as the formation passed over. This was a common problem especially for soldiers who were involved with the initial clash with the enemy. Despite the snapping of the spear, Hoplites could easily switch to the sauroter without great consequence. The rear ranks used...................

173.Vanilla (V. planifolia).
Vanilla is a flavor derived from orchids of the genus Vanilla, primarily from the Mexican species, flat-leaved vanilla (V. planifolia). The word vanilla, derived from the diminutive of the Spanish word vaina (vaina itself meaning sheath or pod), translates simply as ?little pod?. Pre-Columbian Mesoamerican people cultivated the vine of the vanilla orchid, called tlilxochitl by the Aztecs. Spanish conquistador Hernán Cortés is credited with introducing both vanilla and chocolate to Europe in the 1520s.
Initial attempts to cultivate vanilla outside Mexico and Central America proved futile because of the symbiotic relationship between the vanilla orchid and its natural pollinator, the local species of Melipona bee. Pollination is required to set the fruit from which the flavoring is derived. In 1837, Belgian botanist Charles François Antoine Morren discovered this fact and pioneered a method of artificially pollinating the plant. The method proved financially unworkable and was not deployed commercially. In 1841, Edmond Albius, a slave who lived on the French island of Réunion in the Indian Ocean, discovered at the age of 12 that the plant could be hand-pollinated. Hand-pollination allowed global cultivation of the plant.
Three major species of vanilla currently are grown globally, all of which derive from a species originally found in Mesoamerica, including parts of modern-day Mexico. The various subspecies are Vanilla planifolia (syn. V. fragrans), grown on Madagascar, Réunion, and other tropical areas along the Indian Ocean; V. tahitensis, grown in the South Pacific; and V. pompona, found in the West Indies, and Central and South America. The majority of the world's vanilla is the V. planifolia species, more commonly known as Bourbon vanilla (after the former name of Réunion, Île Bourbon) or Madagascar vanilla, which is produced in Madagascar and neighboring islands in the southwestern Indian Ocean, and in Indonesia. Leptotes bicolor is used in the same way in South America.
Vanilla is the second most expensive spice after saffron, because growing the vanilla seed pods is labor-intensive. Despite the expense, vanilla is highly valued for its flavor, which author Frederic Rosengarten, Jr. described in The Book of Spices as "pure, spicy, and delicate"; he called its complex floral aroma a "peculiar bouquet". As a result, vanilla is widely used in both commercial and domestic baking, perfume manufacture and aromatherapy.
History.
The Totonac people, who inhabit the East Coast of Mexico in the present-day state of Veracruz, were the first to cultivate vanilla. According to Totonac mythology, the tropical orchid was born when Princess Xanat, forbidden by her father from marrying a mortal, fled to the forest with her lover. The lovers were captured and beheaded. Where their blood touched the ground, the vine of the tropical orchid grew.
Drawing of Vanilla from the Florentine Codex (circa 1580) and description of its use and properties written in the Nahuatl language.
In the 15th century, Aztecs invading from the central highlands of Mexico conquered the Totonacs, and soon developed a taste for the vanilla pods. They named the fruit tlilxochitl, or "black flower", after the matured fruit, which shrivels and turns black shortly after it is picked. Subjugated by the Aztecs, the Totonacs paid tribute by sending vanilla fruit to the Aztec capital, Tenochtitlan.
Until the mid-19th century, Mexico was the chief producer of vanilla. In 1819, however, French entrepreneurs shipped vanilla fruits to the islands of Réunion and Mauritius in hopes of producing vanilla there. After Edmond Albius discovered how to pollinate the flowers quickly by hand, the pods began to thrive. Soon, the tropical orchids were sent from Réunion Island to the Comoros Islands Seychelles and Madagascar, along with instructions for pollinating them. By 1898, Madagascar, Réunion, and the Comoros Islands produced 200 metric tons of vanilla beans, about 80% of world production. According to the United Nations Food and Agriculture Organisation, Indonesia is currently responsible for the vast majority of the world's Bourbon vanilla production and 58% of the world total vanilla fruit production.
Vanilla cultivation.
The market price of vanilla rose dramatically in the late 1970s after a tropical cyclone ravaged key croplands. Prices remained high through the early 1980s despite the introduction of Indonesian vanilla. In the mid-1980s, the cartel that had controlled vanilla prices and distribution since its creation in 1930 disbanded. Prices dropped 70% over the next few years, to nearly US$20 per kilogram; prices rose sharply again after tropical cyclone Hudah struck Madagascar in April 2000. The cyclone, political instability, and poor weather in the third year drove vanilla prices to an astonishing US$500 per kilogram in 2004, bringing new countries into the vanilla industry. A good crop, coupled with decreased demand caused by the production of imitation vanilla, pushed the market price down to the $40 per kilogram range in the middle of 2005. By 2010, prices were down to US$20/per kilo.
Madagascar (especially the fertile Sava region) accounts for much of the global production of vanilla. Mexico, once the leading producer of natural vanilla with an annual yield of 500 tons, produced only 10 tons of vanilla in 2006. An estimated 95% of "vanilla" products are artificially flavored with vanillin derived from lignin instead of vanilla fruits.
Etymology.
Vanilla was completely unknown in the Old World before Cortés. Spanish explorers arriving on the Gulf Coast of Mexico in the early 16th century gave vanilla its current name. Spanish and Portuguese sailors and explorers brought vanilla into Africa and Asia later that century. They called it vainilla, or "little pod". The word vanilla entered the English language in 1754, when the botanist Philip Miller wrote about the genus in his Gardener?s Dictionary. Vainilla is from the diminutive of vaina, from the Latin vagina (sheath) to describe the shape of the pods.

The main species harvested for vanilla is Vanilla planifolia. Although it is native to Mexico, it is now widely grown throughout the tropics. Indonesia and Madagascar are the world's largest producers. Additional sources include Vanilla pompona and Vanilla tahitiensis (grown in Niue and Tahiti), although the vanillin content of these species is much less than Vanilla planifolia.
Vanilla grows as a vine, climbing up an existing tree (also called a tutor), pole, or other support. It can be grown in a wood (on trees), in a plantation (on trees or poles), or in a "shader", in increasing orders of productivity. Its growth environment is referred to as its terroir, and includes not only the adjacent plants, but also the climate, geography, and local geology. Left alone, it will grow as high as possible on the support, with few flowers. Every year, growers fold the higher parts of the plant downward so the plant stays at heights accessible by a standing human. This also greatly stimulates flowering.
Vanilla planifolia ? flower.
The distinctively flavored compounds are found in the fruit, which results from the pollination of the flower. These seed pods are roughly a third of an inch by six inches, and brownish red to black when ripe. Inside of these pods are an oily liquid full of tiny seeds. One flower produces one fruit. V. planifolia flowers are hermaphroditic: They carry both male (anther) and female (stigma) organs; however, to avoid self-pollination, a membrane separates those organs. The flowers can be naturally pollinated only by bees of the Melipona genus found in Mexico (abeja de monte or mountain bee).[citation needed] This bee provided Mexico with a 300-year-long monopoly on vanilla production, from the time it was first discovered by Europeans. The first vanilla orchid to flower in Europe was in the London collection of the Honourable Charles Greville in 1806. Cuttings from that plant went to Netherlands and Paris, from which the French first transplanted the vines to their overseas colonies. The vines would grow, but would not fruit outside Mexico. Growers tried to bring this bee into other growing locales, to no avail. The only way to produce fruits without the bees is artificial pollination. And today, even in Mexico, hand pollination is used extensively.
In 1836, botanist Charles François Antoine Morren was drinking coffee on a patio in Papantla (in Veracruz, Mexico) and noticed black bees flying around the vanilla flowers next to his table. He watched their actions closely as they would land and work their way under a flap inside the flower, transferring pollen in the process. Within hours, the flowers closed and several days later, Morren noticed vanilla pods beginning to form. Morren immediately began experimenting with hand pollination. A few years later in 1841, a simple and efficient artificial hand-pollination method was developed by a 12-year-old slave named Edmond Albius on Réunion, a method still used today. Using a beveled sliver of bamboo, an agricultural worker lifts the membrane separating the anther and the stigma, then, using the thumb, transfers the pollinia from the anther to the stigma. The flower, self-pollinated, will then produce a fruit. The vanilla flower lasts about one day, sometimes less, so growers have to inspect their plantations every day for open flowers, a labor-intensive task.
The fruit, a seed capsule, if left on the plant, will ripen and open at the end; as it dries, the phenolic compounds crystallize, giving the fruits a diamond-dusted appearance, which the French call givre (hoarfrost). It will then release the distinctive vanilla smell. The fruit contains tiny, black seeds. In dishes prepared with whole natural vanilla, these seeds are recognizable as black specks. Both the pod and the seeds are used in cooking.
Like other orchids' seeds, vanilla seeds will not germinate without the presence of certain mycorrhizal fungi. Instead, growers reproduce the plant by cutting: they remove sections of the vine with six or more leaf nodes, a root opposite each leaf. The two lower leaves are removed, and this area is buried in loose soil at the base of a support. The remaining upper roots will cling to the support, and often grow down into the soil. Growth is rapid under good conditions.
Cultivars.

Bourbon vanilla or Bourbon-Madagascar vanilla, produced from V. planifolia plants introduced from the Americas, is the term used for vanilla from Indian Ocean islands such as Madagascar, the Comoros, and Réunion, formerly the Île Bourbon. It is also used to describe the distinctive vanilla flavor derived from V. planifolia grown successfully in tropical countries such as India.
Mexican vanilla, made from the native V. planifolia, is produced in much less quantity and marketed as the vanilla from the land of its origin. Vanilla sold in tourist markets around Mexico is sometimes not actual vanilla extract, but is mixed with an extract of the tonka bean, which contains coumarin. Tonka bean extract smells and tastes like vanilla, but coumarin has been shown to cause liver damage in lab animals and is banned in food in the US by the Food and Drug Administration since 1954.
Tahitian vanilla is the name for vanilla from French Polynesia, made with the V. tahitiensis strain. Genetic analysis shows this species is possibly a cultivar from a hybrid-cross of V. planifolia and V. odorata. The species was introduced by French Admiral François Alphonse Hamelin to French Polynesia from the Philippines, where it was introduced from Guatemala by the Manila Galleon trade.
West Indian vanilla is made from the V. pompona strain grown in the Caribbean and Central and South America.
The term French vanilla is often used to designate preparations with a strong vanilla aroma, containing vanilla grains and sometimes also containing eggs (especially egg yolks). The appellation originates from the French style of making vanilla ice cream with a custard base, using vanilla pods, cream, and egg yolks. Inclusion of vanilla varietals from any of the former French dependencies or overseas France noted for their exports may in fact be a part of the flavoring, though it may often be coincidental. Alternatively, French vanilla is taken to refer to a vanilla-custard flavor. Syrup labeled as French vanilla may include custard, hazelnut, caramel or butterscotch flavors in addition to vanilla.
Chemistry.
Chemical structure of vanillin.
Main article: Vanillin.
There are many compounds present in the extracts of vanilla. The chemical compound vanillin (4-hydroxy-3-methoxybenzaldehyde) is a major contributor to the characteristic flavor and smell of vanilla, but its contribution is still less than 50%. The contributions of vanilla's hundreds of flavor compounds result in the complex symphony of aroma and flavor that is vanilla. Real vanilla has the most complex of any flavor. Put another way, vanillin does not equal vanilla; it doesn't even approximate it. Another minor component of vanilla essential oil is piperonal (heliotropin). Piperonal and other substances affect the odor of natural vanilla. Vanillin was first isolated from vanilla pods by Gobley in 1858. By 1874, it had been obtained from glycosides of pine tree sap, temporarily causing a depression in the natural vanilla industry.
Vanilla essence comes in two forms. Real seedpod extract is an extremely complicated mixture of several hundred different compounds, including acetaldehyde, acetic acid, furfural, hexanoic acid, 4-hydroxybenzaldehyde, eugenol, methyl cinnamate, and isobutyric acid. Synthetic essence consists of a solution of synthetic vanillin in ethanol. Vanillin can be easily synthesized from various raw materials, but the majority of food grade (>99% pure) vanillin is made from guaiacol.

Vanilla output in 2011.
In general, good vanilla will only come from good vines and through careful production methods. Commercial vanilla production can be performed under open field and "greenhouse" operations. Both production systems share the following similarities:
Plant height and number of years before producing the first grains
Shade necessities
Amount of organic matter needed
A tree or frame to grow around (bamboo, coconut or Erythrina lanceolata)
Labor intensity (pollination and harvest activities)
Vanilla grows best in a hot, humid climate from sea level to an elevation of 1500 m. The ideal climate has moderate rainfall, 1500?3000 mm, evenly distributed through 10 months of the year. Optimum temperatures for cultivation are 15?30 °C (59?86 °F) during the day and 15?20 °C (59?68 °F) during the night. Ideal humidity is around 80%, and under normal greenhouse conditions, it can be achieved by an evaporative cooler. However, since greenhouse vanilla is grown near the equator and under polymer (HDPE) netting (shading of 50%), this humidity can be achieved by the environment. Most successful vanilla growing and processing is done in the region within 10 to 20° of the equator.
Soils for vanilla cultivation should be loose, with high organic matter content and loamy texture. They must be well drained, and a slight slope helps in this condition. Soil pH has not been well documented, but some researchers have indicated an optimum soil pH of around 5.3. Mulch is very important for proper growth of the vine, and a considerable portion of mulch should be placed in the base of the vine. Fertilization varies with soil conditions, but general recommendations are: 40 to 60 g of N, 20 to 30 g of P2O5 and 60 to 100 g of K2O should be applied to each plant per year besides organic manures, such as vermicompost, oil cakes, poultry manure and wood ash. Foliar applications are also good for vanilla, and a solution of 1% NPK (17:17:17) can be sprayed on the plant once a month. Vanilla requires organic matter, so three or four applications of mulch a year are adequate for the plant.
Propagation, preparation and type of stock.
Dissemination of vanilla can be achieved either by stem cutting or by tissue culture. For stem cutting, a progeny garden needs to be established. Recommendations for establishing this garden vary, but in general, trenches of 60 cm (24 in) in width, 45 cm (18 in) in depth and 60 cm (24 in) spacing for each plant are necessary. All plants need to grow under 50% shade, as well as the rest of the crop. Mulching the trenches with coconut husk and micro irrigation provide an ideal microclimate for vegetative growth. Cuttings between 60 and 120 cm (24 and 47 in) should be selected for planting in the field or greenhouse. Cuttings below 60 to 120 cm (24 to 47 in) need to be rooted and raised in a separate nursery before planting. Planting material should always come from unflowered portions of the vine. Wilting of the cuttings before planting provides better conditions for root initiation and establishment.
Before planting the cuttings, trees to support the vine must be planted at least three months before sowing the cuttings. Pits of 30 x 30 x 30 cm are dug 30 cm (12 in) away from the tree and filled with farm yard manure (vermicompost), sand and top soil mixed well. An average of 2000 cuttings can be planted per hectare (2.5 acres). One important consideration is that when planting the cuttings from the base, four leaves should be pruned and the pruned basal point must be pressed into the soil in a way such that the nodes are in close contact with the soil, and are placed at a depth of 15 to 20 cm (5.9 to 7.9 in). The top portion of the cutting is tied to the tree using natural fibers such as banana or hemp.
Tissue culture.
Tissue culture was first used as a means of creating vanilla plants during the 1980s at Tamil Nadu University. This was the part of the first project to grow V. planifolia in India. At that time, a shortage of vanilla planting stock was occurring in India. The approach was inspired by the work going on to tissue culture other flowering plants. Several methods have been proposed for vanilla tissue culture, but all of them begin from axillary buds of the vanilla vine. In vitro multiplication has also been achieved through culture of callus masses, protocorns, root tips and stem nodes. Description of any of these processes can be obtained from the references listed before, but all of them are successful in generation of new vanilla plants that first need to be grown up to a height of at least 30 cm (12 in) before they can be planted in the field or greenhouse.
Scheduling considerations.
In the tropics, the ideal time for planting vanilla is from September to November, when the weather is neither too rainy nor too dry, but this recommendation varies with growing conditions. Cuttings take one to eight weeks to establish roots, and show initial signs of growth from one of the leaf axils. A thick mulch of leaves should be provided immediately after planting as an additional source of organic matter. Three years are required for cuttings to grow enough to produce flowers and subsequent pods. As with most orchids, the blossoms grow along stems branching from the main vine. The buds, growing along the 6 to 10 in (15 to 25 cm) stems, bloom and mature in sequence, each at a different interval.
Pollination.
Flowering normally occurs every spring, and without pollination, the blossom wilts and falls, and no vanilla bean can grow. Each flower must be hand-pollinated within 12 hours of opening. In the wild, very few natural pollinators exist, with most pollination being carried out by bees of the genus Melipona. These pollinators do not exist outside the orchid's home range, and even within that range, vanilla orchids have only a 1% chance of successful pollination. As a result, all vanilla grown today is pollinated by hand. A small splinter of wood or a grass stem is used to lift the rostellum or move the flap upward, so the overhanging anther can be pressed against the stigma and self-pollinate the vine. Generally, one flower per raceme opens per day, so the raceme may be in flower for over 20 days. A healthy vine should produce about 50 to 100 beans per year, but growers are careful to pollinate only five or six flowers from the 20 on each raceme. The first flowers that open per vine should be pollinated, so the beans are similar in age. These agronomic practices facilitate harvest and increases bean quality. It takes the fruits five to six weeks to develop, but it takes around six months for the bean to mature. Over-pollination will result in diseases and inferior bean quality. A vine remains productive between 12 and 14 years.
Pest and disease management.
Most diseases come from the uncharacteristic growing conditions of vanilla. Therefore, conditions such as excess water, insufficient drainage, heavy mulch, overpollination and too much shade favor disease development. Vanilla is susceptible to many fungal and viral diseases. Fusarium, Sclerotium, Phytophthora, and Colletrotrichum species cause rots of root, stem, leaf, bean and shoot apex. These diseases can be controlled by spraying Bordeaux mixture (1%), carbendazim (0.2%) and copper oxychloride (0.2%).
Biological control of the spread of such diseases can be managed by applying to the soil Trichoderma (0.5 kg (1.1 lb) per plant in the rhizosphere) and foliar application of pseudomonads (0.2%). Mosaic virus, leaf curl and cymbidium mosaic potex virus are the common viral diseases. These diseases are transmitted through the sap, so affected plants must be destroyed. The insect pests of vanilla include beetles and weevils that attack the flower, caterpillars, snakes and slugs that damage the tender parts of shoot, flower buds and immature fruit, and grasshoppers that affect cutting shoot tips. If organic agriculture is practiced, insecticides are avoided, and mechanical measures are adopted for pest management. Most of these practices are implemented under greenhouse cultivation, since such field conditions are very difficult to achieve.
Artificial vanilla.
Most artificial vanilla products contain vanillin, which can be produced synthetically from lignin, a natural polymer found in wood. Most synthetic vanillin is a byproduct from the pulp used in papermaking, in which the lignin is broken down using sulfites or sulfates. However, vanillin is only one of 171 identified aromatic components of real vanilla fruits.
The orchid species Leptotes bicolor is used as a natural vanilla replacement in Paraguay and southern Brazil.
Nonplant vanilla flavoring.
In the United States, castoreum, the exudate from the castor sacs of mature beavers, has been approved by the Food and Drug Administration (FDA) as a food additive, often referenced simply as a "natural flavoring" in the product's list of ingredients. It is commonly used in both food and beverages, especially as vanilla and raspberry flavoring. It is also used to flavor some cigarettes and in perfume-making.
Stages of production.

Harvest.
The vanilla fruit grows quickly on the vine, but is not ready for harvest until maturity?approximately six months. Harvesting vanilla fruits is as labor-intensive as pollinating the blossoms. Immature dark green pods are not harvested. Pale yellow discoloration that commences at the distal end of the fruits is an indication of the maturity of pods. Each fruit ripens at its own time, requiring a daily harvest. To ensure the finest flavor from every fruit, each individual pod must be picked by hand just as it begins to split on the end. Overmatured fruits are likely to split, causing a reduction in market value. Its commercial value is fixed based on the length and appearance of the pod.
If the fruit is more than 15 cm (5.9 in) in length, it belongs to first-quality product. The largest fruits greater than 16 cm and up to as much as 21 cm are usually reserved for the gourmet vanilla market, for sale to top chefs and restaurants. If the fruits are between 10 and 15 cm long, pods are under the second-quality category, and fruits less than 10 cm in length are under the third-quality category. Each fruit contains thousands of tiny black vanilla seeds. Vanilla fruit yield depends on the care and management given to the hanging and fruiting vines. Any practice directed to stimulate aerial root production has a direct effect on vine productivity. A five-year-old vine can produce between 1.5 and 3 kg (3.3 and 6.6 lb) pods, and this production can increase up to 6 kg (13 lb) after a few years. The harvested green fruit can be commercialized as such or cured to get a better market price.
Curing.
Several methods exist in the market for curing vanilla; nevertheless, all of them consist of four basic steps: killing, sweating, slow-drying, and conditioning of the beans.
Killing.
The vegetative tissue of the vanilla pod is killed to stop the vegetative growth of the pods and disrupt the cells and tissue of the fruits, which initiates enzymatic reactions responsible for the aroma. The method of killing varies, but may be accomplished by heating in hot water, freezing, or scratching, or killing by heating in an oven or exposing the beans to direct sunlight. The different methods give different profiles of enzymatic activity.
Testing has shown mechanical disruption of fruit tissues can cause curing processes, including the degeneration of glucovanillin to vanillin, so the reasoning goes that disrupting the tissues and cells of the fruit allow enzymes and enzyme substrates to interact.
Hot-water killing may consist of dipping the pods in hot water (63?65 °C (145?149 °F)) for three minutes, or at 80 °C (176 °F) for 10 seconds. In scratch killing, fruits are scratched along their length. Frozen or quick-frozen fruits must be thawed again for the subsequent sweating stage. Tied in bundles and rolled in blankets, fruits may be placed in an oven at 60 °C (140 °F) for 36 to 48 hours. Exposing the fruits to sunlight until they turn brown is a method originating in Mexico that was practiced by the Aztecs.
Sweating.
Sweating is a hydrolytic and oxidative process. Traditionally, it consists of keeping fruits, for seven to 10 days, densely stacked and insulated in wool or other cloth. This retains a temperature of 45?65 °C (113?149 °F) and high humidity. Daily exposure to the sun may also be used, or dipping the fruits in hot water. The fruits are brown and have attained much of the characteristic vanilla flavor and aroma by the end of this process, but still retain a 60-70% moisture content by weight.
Drying.
Reduction of the beans to 25?30% moisture by weight, to prevent rotting and to lock the aroma in the pods, is always achieved by some exposure of the beans to air, and usually (and traditionally) intermittent shade and sunlight. Fruits may be laid out in the sun during the mornings and returned to their boxes in the afternoons, or spread on a wooden rack in a room for three to four weeks, sometimes with periods of sun exposure. Drying is the most problematic of the curing stages; unevenness in the drying process can lead to the loss of vanillin content of some fruits by the time the others are cured.

Conditioning.
Conditioning is performed by storing the pods for five to six months in closed boxes, where the fragrance develops. The processed fruits are sorted, graded, bundled, and wrapped in paraffin paper and preserved for the development of desired bean qualities, especially flavor and aroma. The cured vanilla fruits contain an average of 2.5% vanillin.
Grading.
See also: Food grading.
Once fully cured, the vanilla fruits are sorted by quality and graded.
Several vanilla fruit grading systems are in use. Each country which produces vanilla has its own grading system, and individual vendors, in turn, sometimes use their own criteria for describing the quality of the fruits they offer for sale.
In general, vanilla fruit grade is based on the length, appearance (color, sheen, presence of any splits, presence of blemishes), and moisture content of the fruit. Whole, dark, plump and oily pods that are visually attractive, with no blemishes, and that have a higher moisture content are graded most highly. Such pods are particularly prized by chefs for their appearance and can be featured in gourmet dishes. Beans that show localized signs of disease or other physical defects are cut to remove the blemishes; the shorter fragments left are called ?cuts? and are assigned lower grades, as are fruits with lower moisture contents. Lower-grade fruits tend to be favored for uses in which the appearance is not as important, such as in the production of vanilla flavoring extract and in the fragrance industry.
Higher-grade fruits command higher prices in the market. However, because grade is so dependent on visual appearance and moisture content, fruits with the highest grade do not necessarily contain the highest concentration of characteristic flavor molecules such as vanillin, and are not necessarily the most flavorful.

A simplified, alternative grading system has been proposed for classifying vanilla fruits suitable for use in cooking:

Grade A /
Grade I15 cm and longer, 100?120 fruits per poundAlso called "Gourmet" or "Prime". 30?35% moisture content.
Grade B /
Grade II10?15 cm, 140?160 fruits per poundAlso called "Extract fruits". 15?25% moisture content.
Grade C /

Under this scheme, vanilla extract is normally made from Grade B fruits.
Usage.

There are four main commercial preparations of natural vanilla:
whole pod
powder (ground pods, kept pure or blended with sugar, starch, or other ingredients)
extract (in alcoholic or occasionally glycerol solution; both pure and imitation forms of vanilla contain at least 35% alcohol)
vanilla sugar, a pre-packaged mix of sugar and vanilla extract
Cook Flavoring Company's Pure Vanilla Powder
Vanilla flavoring in food may be achieved by adding vanilla extract or by cooking vanilla pods in the liquid preparation. A stronger aroma may be attained if the pods are split in two, exposing more of a pod's surface area to the liquid. In this case, the pods' seeds are mixed into the preparation. Natural vanilla gives a brown or yellow color to preparations, depending on the concentration. Good-quality vanilla has a strong aromatic flavor, but food with small amounts of low-quality vanilla or artificial vanilla-like flavorings are far more common, since true vanilla is much more expensive.
A major use of vanilla is in flavoring ice cream. The most common flavor of ice cream is vanilla, and thus most people consider it to be the "default" flavor. By analogy, the term "vanilla" is sometimes used as a synonym for "plain". Although vanilla is a prized flavoring agent on its own, it is also used to enhance the flavor of other substances, to which its own flavor is often complementary, such as chocolate, custard, caramel, coffee, cakes, and others.
The food industry uses methyl and ethyl vanillin. Ethyl vanillin is more expensive, but has a stronger note. Cook's Illustrated ran several taste tests pitting vanilla against vanillin in baked goods and other applications, and, to the consternation of the magazine editors, tasters could not differentiate the flavor of vanillin from vanilla; however, for the case of vanilla ice cream, natural vanilla won out. A more recent and thorough test by the same group produced a more interesting variety of results; namely, high-quality artificial vanilla flavoring is best for cookies, while high-quality real vanilla is very slightly better for cakes and significantly better for unheated or lightly heated foods.
It was once believed that the liquid extracted from vanilla pods had medical properties, helping with various stomach ailments.

174.Jupiter Ascending, movie file.
Jupiter Ascending is a 2015 American-Australian space opera film written, produced, and directed by Lana and Andy Wachowski. Starring Channing Tatum and Mila Kunis, the film is centered on Jupiter Jones (Kunis), a down-on-her-luck cleaning woman, and Caine Wise (Tatum), an interplanetary warrior who informs Jones that her destiny extends beyond Earth. Supporting cast member Douglas Booth has described the film's fictional universe as a cross between The Matrix and Star Wars, while Kunis named indulgence and consumerism as its underlying themes.
The film was co-produced by Grant Hill, who acted as executive producer on The Matrix Reloaded and The Matrix Revolutions and as producer on V for Vendetta, Speed Racer, Ninja Assassin and Cloud Atlas, making Jupiter Ascending his seventh collaboration with the Wachowskis. Several more longstanding Wachowski collaborators since the creation of The Matrix films have contributed to the picture, including production designer Hugh Bateup, visual effects supervisor Dan Glass, visual effects designer John Gaeta, supervising sound editor Dane Davis and costume designer Kym Barrett. Other notable past collaborators include Speed Racer's composer Michael Giacchino, Cloud Atlas' director of photography John Toll along with its editor Alexander Berner and hair and make-up designer Jeremy Woodhead, who worked on both.
Although critics praised the visuals, world-building, and originality, the general attitude toward the film was negative, with most criticism focused on incoherence in the screenplay and an over-reliance on special effects. Despite this, the film has found a niche following, particularly among female sci-fi fans who appreciate the film's campiness, and that the film deviates from typical gender dynamics in a genre that is traditionally male-centric.
Plot.
At the beginning of the story, Earth's residents are unaware that the human species on Earth and countless other planets has been established by families of alien* royalty for the purpose of later "harvesting" the resulting organisms to produce a type of youth serum* for the elites on still other planets. After the death of the matriarch* of the House of Abrasax, the most powerful of the alien dynasties, her children, Balem (Eddie Redmayne), Kalique (Tuppence Middleton), and Titus (Douglas Booth), quarrel over the inheritance, with Balem inheriting an enormous production facility on Jupiter* and Titus declaring his intention to dismantle the youth serum trade, of which Earth is the next intended source. Protagonist Jupiter Jones narrates that her father, Maximilian Jones (James D'Arcy), met her mother, Aleksa (Maria Doyle Kennedy), in Saint Petersburg. After Maximilian is killed in a robbery, Aleksa names their daughter Jupiter, after his dying wish, and they move to Chicago to live with Aleksa's family.
Many years later, Jupiter (Mila Kunis) works with Aleksa and her Aunt Nino (Frog Stone) and cleans the homes of wealthy people. To buy a telescope, Jupiter agrees to sell her eggs with the help of her cousin Vladie (Kick Gurry), under the name of her friend Katharine Dunlevy (Vanessa Kirby). At Katharine's house, Jupiter and Katharine are attacked by Extraterrestrial Keepers*; when Jupiter photographs them, they erase her memory of the incident. During the egg donation procedure, the doctors and nurses are identified as Balem's agents, sent to kill her, and she is saved by Caine Wise (Channing Tatum), a genetically engineered ex-soldier sent by Titus. Stinger Apini (Sean Bean), an old comrade of Caine's, agrees to help Jupiter, but a group of hunters take her to Kalique's palace on a distant planet, where Kalique explains that Jupiter is genetically identical to the dead matriarch, and therefore the Earth's rightful owner. Supported by Captain Diomika Tsing (Nikki Amuka-Bird) of the Aegis* (an intergalactic police force), Caine retrieves her from Kalique, and brings her to the planet Ores (the intergalactic capital city) to claim her inheritance.
On the way back to Earth, Titus detains Jupiter and Caine. He reveals his plan to marry and then kill Jupiter and claim Earth before throwing Caine into the void*, but Caine survives and saves Jupiter at the altar. Jupiter asks to return home, but her family has been taken hostage by Balem. In his citadel in the Great Red Spot*, Balem demands Earth in exchange for Jupiter's family. Realizing that Balem can "harvest" Earth only with her permission, Jupiter refuses. Balem tries to kill Jupiter; but she defeats him in a fight. She escapes and is rescued by Caine, Stinger, and Tsing. Jupiter's family is returned home with no memory of her disappearance, while Jupiter secretly retains ownership of the Earth. Her family buys her the telescope she wanted and Caine receives a pair of wings earlier removed from his body.
*Alien/Extraterrestrial life is life that does not originate from Earth. It is also called alien life, or, if it is a sentient and/or relatively complex individual, an "extraterrestrial" or "alien" (or, to avoid confusion with the legal sense of "alien", a "space alien"). These as yet hypothetical forms of life range from simple bacteria-like organisms to beings far more complex than humans. The possibility that viruses might exist extraterrestrially has also been proposed.
*Youth serum/Eternal youth is the concept of human physical immortality free of aging. The youth referred to is usually meant to be in contrast to the depredations of aging, rather than a specific age of the human lifespan. Achieving eternal youth so far remains beyond the capabilities of scientific technology. However, much research is being conducted in the sciences of genetics which may allow manipulation of the aging process in the future.[citation needed] Eternal youth is common in mythology, and is a popular theme in fiction.
*Matriarch/A matriarchy is a social organizational form in which the mother or oldest female heads the family. Descent and relationship are determined through the female line. It is also government or rule by a woman or women. While those definitions apply in general English, definitions specific to the disciplines of anthropology and feminism differ in some respects.
Most anthropologists hold that there are no known societies that are unambiguously matriarchal, but some authors believe that exceptions are possible, some of them in the past. Matriarchies may also be confused with matrilineal, matrilocal, and matrifocal societies. A few people consider any non-patriarchal system to be matriarchal, thus including genderally equalitarian systems, but most academics exclude them from matriarchies strictly defined.
In 19th century Western scholarship, the hypothesis of matriarchy representing an early stage of human development?now mostly lost in prehistory, with the exception of some so-called primitive societies?enjoyed popularity. The hypothesis survived into the 20th century and was notably advanced in the context of second-wave feminism, but this hypothesis is mostly discredited today. Some older myths describe matriarchies. Several modern feminists have advocated for matriarchy now or in the future and it has appeared in feminist fiction. In several theologies, matriarchy has been seen as a negative force.
*Jupiter is the fifth planet from the Sun and the largest planet in the Solar System. It is a giant planet with a mass one-thousandth of that of the Sun, but is two and a half times that of all the other planets in the Solar System combined. Jupiter is a gas giant, along with Saturn (Uranus and Neptune are ice giants). Jupiter was known to astronomers of ancient times. The Romans named it after their god Jupiter. When viewed from Earth, Jupiter can reach an apparent magnitude of ?2.94, bright enough to cast shadows, and making it on average the third-brightest object in the night sky after the Moon and Venus. (Mars can briefly match Jupiter's brightness at certain points in its orbit.)
Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, although helium only comprises about a tenth of the number of molecules. It may also have a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface. Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. A prominent result is the Great Red Spot, a giant storm that is known to have existed since at least the 17th century when it was first seen by telescope. Surrounding Jupiter is a faint planetary ring system and a powerful magnetosphere. Jupiter has at least 67 moons, including the four large Galilean moons discovered by Galileo Galilei in 1610. Ganymede, the largest of these, has a diameter greater than that of the planet Mercury.
*Earth, also called the world[n 4] and, less frequently, Gaia[n 5] (and Terra in some works of science fiction) is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System's four terrestrial planets, and the only astronomical object known to accommodate life. The earliest life on Earth arose at least 3.5 billion years ago. Earth's biodiversity has expanded continually except when interrupted by mass extinctions. Although scholars estimate that over 99 percent of all species that ever lived on the planet are extinct, Earth is currently home to 10?14 million species of life, including over 7.3 billion humans who depend upon its biosphere and minerals. Earth's human population is divided among about two hundred sovereign states which interact through diplomacy, conflict, travel, trade and communication media.
According to evidence from radiometric dating and other sources, Earth was formed around four and a half billion years ago. Within its first billion years, life appeared in its oceans and began to affect its atmosphere and surface, promoting the proliferation of aerobic as well as anaerobic organisms and causing the formation of the atmosphere's ozone layer. This layer and the geomagnetic field blocked the most life-threatening parts of the Sun's radiation, so life was able to flourish on land as well as in water. Since then, the combination of Earth's distance from the Sun, its physical properties and its geological history have allowed life to thrive and evolve.
Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. Seventy-one percent of Earth's surface is covered with water, with the remainder consisting of continents and islands that together have many lakes and other sources of water that contribute to the hydrosphere. Earth's poles are mostly covered with ice that includes the solid ice of the Antarctic ice sheet and the sea ice of the polar ice packs. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates the magnetic field, and a thick layer of relatively solid mantle.
Earth gravitationally interacts with other objects in space, especially the Sun and the Moon. During one orbit around the Sun, Earth rotates about its own axis 366.26 times, creating 365.26 solar days or one sidereal year.[n 6] Earth's axis of rotation is tilted 23.4° away from the perpendicular of its orbital plane, producing seasonal variations on the planet's surface with a period of one tropical year (365.24 solar days). The Moon is Earth's only natural satellite. It began orbiting Earth about 4.53 billion years ago. The Moon's gravitational interaction with Earth stimulates ocean tides, stabilizes the axial tilt and gradually slows the planet's rotation.
*Extraterrestrial Keepers/Grey aliens, also referred to as "Alien Greys", "Greys", "Grays", "Roswell Greys", and "Zeta Reticulans", are alleged extraterrestrial beings whose existence is promoted in ufological, paranormal, and New Age communities, and who are named for their skin color. Around half of all reported alien encounters in the United States describe Grey aliens. Such claims vary in every respect including their nature (ETs, extradimensionals, demons, or machines), origins, moral dispositions, intentions, and physical appearances (even varying in their eponymous skin color). A composite description derived from overlap in claims would have Greys as small-bodied sexless beings with smooth grey-colored skin, enlarged head and large black eyes.
The origin of the idea of the Grey is commonly associated with the Betty and Barney Hill abduction claim which took place in 1961, although skeptics see precursors in science fiction and earlier paranormal claims. The Grey aliens are also famous from later depictions of the Roswell UFO incident from 1947.
*Aegis. The aegis or aigis (Ancient Greek: ?????; English pronunciation: /?i?d??s/), as stated in the Iliad, is carried by Athena and Zeus, but its nature is uncertain. It had been interpreted as an animal skin or a shield, sometimes bearing the head of a Gorgon. There may be a connection with a deity named Aex or Aix, a daughter of Helios and a nurse of Zeus or alternatively a mistress of Zeus (Pseudo-Hyginus, Astronomica 2. 13). The aegis of Athena is referred to in several places in the Iliad. It produced a sound as from a myriad roaring dragons (Iliad, 4.17) and was borne by Athena in battle "... and among them went bright-eyed Athene, holding the precious aegis which is ageless and immortal: a hundred tassels of pure gold hang fluttering from it, tight-woven each of them, and each the worth of a hundred oxen."
The modern concept of doing something "under someone's aegis" means doing something under the protection of a powerful, knowledgeable, or benevolent source. The word aegis is identified with protection by a strong force with its roots in Greek mythology and adopted by the Romans; there are parallels in Norse mythology and in Egyptian mythology as well, where the Greek word aegis is applied by extension.
*Cosmic voids are the vast empty spaces between filaments (the largest-scale structures in the Universe), which contain very few, or no, galaxies. They were first discovered in 1978 during a pioneering study by Stephen Gregory and Laird A. Thompson at the Kitt Peak National Observatory. These zones have less than one-tenth of the average density of matter abundance that is considered typical for the observable Universe. Voids typically have a diameter of 11 to 150 megaparsecs; particularly large voids, defined by the absence of rich superclusters, are sometimes called "supervoids". Voids located in high-density environments are smaller than voids situated in low-density spaces of the universe.
Voids are believed to have been formed by baryon acoustic oscillations in the Big Bang?collapses of mass followed by implosions of the compressed baryonic matter. Starting from initially small anisotropies due to quantum fluctuations in the early Universe, the anisotropies grew larger in scale over time. Regions of higher density collapsed more rapidly under gravity, eventually resulting in the large-scale, foam-like structure or ?cosmic web? of voids and galaxy filaments seen today.
Voids appear to correlate with the observed temperature of the cosmic microwave background (CMB), due to the Sachs?Wolfe effect. Colder regions correlate with voids, whereas hotter regions correlate with filaments, because of gravitational redshifting. As the Sachs?Wolfe effect is only significant if the Universe is dominated by radiation or dark energy, the existence of voids is significant in providing physical evidence for dark energy.
*Great Red Spot. The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide and water. Although water is thought to reside deep in the atmosphere, its directly measured concentration is very low. The oxygen, nitrogen, sulfur, and noble gas abundances in Jupiter's atmosphere exceed solar values by a factor of about three.
The atmosphere of Jupiter lacks a clear lower boundary and gradually transitions into the liquid interior of the planet. From lowest to highest, the atmospheric layers are the troposphere, stratosphere, thermosphere and exosphere. Each layer has characteristic temperature gradients. The lowest layer, the troposphere, has a complicated system of clouds and hazes, comprising layers of ammonia, ammonium hydrosulfide and water. The upper ammonia clouds visible at Jupiter's surface are organized in a dozen zonal bands parallel to the equator and are bounded by powerful zonal atmospheric flows (winds) known as jets. The bands alternate in color: the dark bands are called belts, while light ones are called zones. Zones, which are colder than belts, correspond to upwellings, while belts mark descending air. The zones' lighter color is believed to result from ammonia ice; what gives the belts their darker colors is not known with certainty. The origins of the banded structure and jets are not well understood, though two models exist. The shallow model holds that they are surface phenomena overlaying a stable interior. In the deep model, the bands and jets are just surface manifestations of deep circulation in Jupiter's mantle of molecular hydrogen, which is organized into cylinders.
The Jovian atmosphere shows a wide range of active phenomena, including band instabilities, vortices (cyclones and anticyclones), storms and lightning. The vortices reveal themselves as large red, white or brown spots (ovals). The largest two spots are the Great Red Spot (GRS) and Oval BA, which is also red. These two and most of the other large spots are anticyclonic. Smaller anticyclones tend to be white. Vortices are thought to be relatively shallow structures with depths not exceeding several hundred kilometers. Located in the southern hemisphere, the GRS is the largest known vortex in the Solar System. It could engulf two or three Earths and has existed for at least three hundred years. Oval BA, south of GRS, is a red spot a third the size of GRS that formed in 2000 from the merging of three white ovals.
Jupiter has powerful storms, often accompanied by lightning strikes. The storms are a result of moist convection in the atmosphere connected to the evaporation and condensation of water. They are sites of strong upward motion of the air, which leads to the formation of bright and dense clouds. The storms form mainly in belt regions. The lightning strikes on Jupiter are hundreds of times more powerful than those seen on Earth. However, there are so few, that the amount of lightning activity is comparable to Earth.
