Laser Towards Milky Ways Centre

Laser Towards Milky Ways Centre


DescriptionEnglish: In mid-August 2010 ESO Photo Ambassador Yuri Beletsky snapped this photo at ESO’s Paranal Observatory, Chile. A group of astronomers were observing the centre of the Milky Way using the laser guide star facility at Yepun, one of the four Unit Telescopes of the Very Large Telescope (VLT).
Yepun’s laser beam crosses the southern sky and creates an artificial star at an altitude of 90 km high in the Earth's mesosphere. The Laser Guide Star (LGS) is part of the VLT’s adaptive optics system and is used as a reference to correct the blurring effect of the atmosphere on images. The colour of the laser is precisely tuned to energise a layer of sodium atoms found in one of the upper layers of the atmosphere — one can recognise the familiar colour of sodium street lamps in the colour of the laser. This layer of sodium atoms is thought to be a leftover from meteorites entering the Earth’s atmosphere. When excited by the light from the laser, the atoms start glowing, forming a small bright spot that can be used as an artificial reference star for the adaptive optics. Using this technique, astronomers can obtain sharper observations. For example, when looking towards the centre of our Milky Way, researchers can better monitor the galactic core, where a central supermassive black hole, surrounded by closely orbiting stars, is swallowing gas and dust.
Taken with a wide angle lens, this photo covers about 180° of the sky.

Constellation

Constellation

In modern astronomy, a constellation is an internationally defined area of the celestial sphere. Historically, the term was also used to refer to a pattern formed by prominent stars within apparent proximity to one another, and this practice is still common today.


Definition

In colloquial usage, a constellation is a group of celestial bodies, usually stars, which appear to form a pattern in the sky. Astronomers today still utilize the term, though the current system focuses primarily on constellations as grid-like segments of the celestial sphere rather than as patterns. A star-pattern that is not officially classed as a constellation is referred to as an asterism. One famous example is the asterism known as the Big Dipper, a term unused by the International Astronomical Union (IAU) as the stars are considered part of the larger constellation of Ursa Major.

In 1922, Eugène Delporte aided the IAU in dividing the celestial sphere into 88 official constellations. Typically, these modern constellations share the names of their Graeco-Roman predecessors, such as Orion, Leo and Scorpius. While such celestial formations were originally linked to a mythical event, creature or person, the categorization of the night sky into recognizable patterns was important in early land and naval navigation prior to the invention of the compass during the Age of Discovery. With the technical advancement of astronomy, it became important to move from a pattern-based system of constellations to one based on area-mapping, which led to several historic formations becoming obsolete.


Boundaries

In 1930, the boundaries between the 88 official constellations were devised by Delporte along vertical and horizontal lines of right ascension and declination. However, the data he used originated back to epoch B1875.0, which was when Benjamin A. Gould first made the proposal to designate boundaries for the celestial sphere, a suggestion upon which Delporte would base his work. The consequence of this early date is that due to the precession of the equinoxes, the borders on a modern star map, such as epoch J2000, are already somewhat skewed and no longer perfectly vertical or horizontal. This effect will increase over the years and centuries to come.


Proximity

The stars within a constellation rarely have any substantial astrophysical relationship to each other, and their apparent proximity when viewed from Earth disguises the fact that they typically lie light years apart. However, there are some exceptions: the constellation of Ursa Major is almost entirely constituted by stars approximate to one another, a phenomenon known as the Ursa Major moving group.


Constellation systems across the world

Graeco-Roman

In the Western world, the sky of the northern hemisphere is traditionally divided into constellations based on those described by the Ancient Greeks. The first ancient Greek works which dealt with the constellations were books of star myths. The oldest of these was a poem composed by Hesiod in or around the eighth century BC, of which only fragments survive. The most complete existing works dealing with the mythical origins of the constellations are by the Hellenistic writer termed pseudo-Eratosthenes and an early Roman writer styled pseudo-Hyginus.

In the 2nd century AD, the Greek astronomer Ptolemy described the constellations in great detail in his influential work the Almagest.

Chinese

Chinese constellations are different from the Western constellations due to the independent development of ancient Chinese astronomy One difference is that the Chinese counterpart of the 12 western zodiac constellations is the 28 "Xiu" (宿) or "mansions" (a literal translation).

Indian

In Vedic astrology, the 12 zodiac constellations are called raasis. The twelve raasis along the ecliptic correspond directly to the twelve western star signs. These are however divided into 27 Nakshatras, or lunar houses.


Dark cloud constellations

In the southern hemisphere, it is possible to discern dark patches in the Milky Way. Some cultures have discerned shapes in these patches and have given names to these "dark cloud constellations." Members of the Inca civilization identified various dark areas or dark nebulae in the Milky Way as animals, and associated their appearance with the seasonal rains. Australian Aboriginal astronomy

Andromeda (Greek)

Andromeda

Alternative Names (異名):
Andromeda, Ανδρομέδη, Andromedē, 안드로메다



Andromeda was a woman from Greek mythology who was chained to a rock to be a sacrifice to a sea monster as divine punishment for her mother's bragging. She was saved from death by Perseus, her future husband. Her name is the Latinized form of the Greek Ανδρομέδη (Andromedē). The etymology of the name is "to think of a man," from ανδρος (andros) "man" combined with μηδομαι (mēdomai) "to think, to be mindful of."



Myth

In Greek mythology, Andromeda was the daughter of Cepheus and Cassiopeia, king and queen of the Phoenician kingdom Ethiopia.

Her mother Cassiopeia bragged that she was more beautiful than the Nereids, the nymph-daughters of the sea god Nereus and often seen accompanying Poseidon. To punish the Queen for her arrogance, Poseidon, brother to Zeus and God of the Sea, sent a sea monster, Cetus, to ravage the coast of Ethiopia and the kingdom of the vain Queen. The desperate King consulted the Ammon, the Oracle of Zeus, who announced that no respite would be found until the king sacrificed his virgin daughter Andromeda to the monster. She was duly chained to a rock on the coast.

Perseus, returning from having slain the Gorgon Medusa, found Andromeda and slew the monster Cetus. He set her free, and married her in spite of Andromeda having been previously promised to Phineus. At the wedding a quarrel took place between the rivals, and Phineus was turned to stone by the sight of the Gorgon's head (Ovid, Metamorphoses v. 1).

Andromeda followed her husband to Tiryns in Argos, and together they became the ancestors of the family of the Perseidae through the line of their son Perses. Perseus and Andromeda had six sons Perseides, Perses, Alcaeus, Heleus, Mestor, Sthenelus, and Electryon, and one daughter, Gorgophone. Their descendants ruled Mycenae from Electryon down to Eurystheus, after whom Atreus attained the kingdom, and would also include the great hero Heracles. According to this mythology, Perses is the ancestor of the Persians.

After her death she was placed by Athena amongst the constellations in the northern sky, near Perseus and Cassiopeia. Sophocles and Euripides (and in more modern times Corneille) made the story the subject of tragedies. The tale is represented in numerous ancient works of art.


Constellations

Andromeda is represented in the northern sky by the constellation Andromeda which contains the Andromeda Galaxy.

Four constellations are associated with the myth. Viewing the fainter stars, visible to the naked eye, the constellations are rendered as:

A large man wearing a crown, upside down with respect to the ecliptic. (The constellation Cepheus)
A smaller figure, next to the man, sitting on a chair. As it is near the pole star, it can be seen the whole year, although sometimes upside down. (The constellation Cassiopeia)
A maiden, chained up, facing/turning away from the ecliptic. (The constellation Andromeda), next to Pegasus.

A sea monster just under the ecliptic. (The constellation Cetus)

The king of Ethiopia Cepheus and the Cassiopeia queen thank Perseus for freeing their daughter Andromeda, La Délivrance d'Andromède (1679) Pierre Mignard, Louvre.Other constellations related to the story are:

Perseus
The constellation Pegasus, who was born from the stump of Medusa's neck, after Perseus had decapitated her.

The constellation Pisces, which may have been treated as two fish caught by Dictys the fisherman who was brother of Polydectes king of Seriphos where Perseus and his mother Danaë were stranded.

Chinese astrology (占星术)

Chinese astrology

Alternative Names (異名):
Chinese astrology, 星术 [xīngshù], 占星术 [zhānxīngshù]


Chinese astrology is the divination of the future from the Chinese calendar, which is based on astronomy, and ancient Chinese philosophy. In particular, it is based on the sexagenary cycle of 60 years that has been documented since at least the time of the Shang Dynasty. This basic cycle has been constructed from two cycles: the 10 heavenly stems (the five elements in their yin and yang forms) and the 12 earthly branches, or the 12-year cycle of animals referred to as the Chinese zodiac. The Chinese animal zodiac also operates on a cycle of months or 'moons' and of hours of the day.

The Chinese zodiac refers to a pure calendrical cycle; there are no equivalent constellations like those of the occidental zodiac. In imperial times there were astrologers who watched the sky for heavenly omens that would predict the future of the state, but this was a quite different practice of divination from the popular present-day methods.


Background

The ancient Chinese astronomers called the 5 major planets by the names of the element they were associated with: Venus corresponds to Metal (gold); Jupiter to Wood; Mercury to Water; Mars to Fire; Saturn to Earth. According to Chinese Astrology, a person's destiny can be determined by the position of the major planets, along with the positions of the Sun, Moon and comets and the person's time of birth and Zodiac Sign. The system of the twelve year cycle of animal signs was built from observations of the orbit of Jupiter. Chinese astronomers divided the celestial circle into 12 sections to follow the orbit of 歳星 Suìxīng (Jupiter, the Year Star). Astronomers rounded the orbit of Suixing to 12 years (from 11.86). Suixing was associated with Sheti (ɳ Böotes) and sometimes called Sheti.

A laborious system of computing one's fate and destiny based on one's birthday and birth hours (known as Zi Wei Dou Shu 紫微斗數 zǐwēidǒushù) is still used regularly in modern day Chinese astrology to divine one's fortune. The 28 Chinese constellations (宿 xìu) are quite different from the 88 Western constellations. For example, the Big Bear (Ursa Major) is known as 斗 dǒu; the belt of Orion is known as 參 shēn, or the "Happiness, Fortune, Longevity" trio of demigods. The seven northern constellations are referred to as xúanwǔ (玄武). Xuan Wu is also known as the spirit of the northern sky or the spirit of Water in Taoism belief.

In addition to astrological readings of the heavenly bodies, the stars in the sky form the basis of many fairy tales. For example, the Summer Triangle is the trio of the cowherd (Altair), the weaving maiden fairy (Vega), and the "tai bai" fairy (Deneb). The two forbidden lovers were separated by the silvery river (the Milky Way). Each year on the seventh day of the seventh month in the Chinese calendar, the birds form a bridge across the Milky Way. The cowherd carries their two sons (the two stars on each side of Altair) across the bridge to reunite with their fairy mother. The tai bai fairy acts as the chaperone of these two immortal lovers. See Qi Xi for more versions of this story.


Lunisolar calendar

The 60-year cycle consists of two separate cycles interacting with each other. The first is the cycle of ten heavenly stems, namely the Five Elements (in order Wood, Fire, Earth, Metal, and Water) in their Yin and Yang forms.

The second is the cycle of the twelve Zodiac animal signs (生肖 shēngxiāo) or Earthly Branches . They are in order as follows: the rat, ox, tiger, rabbit, dragon, snake, horse, sheep (ram or goat), monkey, rooster, dog, and boar .

This combination of 5 elements × 12 animals creates the 60-year cycle, which always starts with Wood Rat and ends with Water Boar. Since the zodiac animal cycle of 12 is divisible by two, every zodiac sign can also only occur in either yin or yang: the dragon is always yang, the snake is always yin, etc. The current cycle began in the year 1984 .

When trying to calculate the relevant year, an easy rule to follow is that years that end in an even number are yang, those that end with an odd number are yin. The cycle proceeds as follows:

If the year ends in 0 it is Yang Metal.
If the year ends in 1 it is Yin Metal.
If the year ends in 2 it is Yang Water.
If the year ends in 3 it is Yin Water.
If the year ends in 4 it is Yang Wood.
If the year ends in 5 it is Yin Wood.
If the year ends in 6 it is Yang Fire.
If the year ends in 7 it is Yin Fire.
If the year ends in 8 it is Yang Earth.
If the year ends in 9 it is Yin Earth.

However, since the (traditional) Chinese zodiac follows the (lunisolar) Chinese calendar, the switch over date is the Chinese New Year, not January 1 as in the Gregorian calendar. Therefore, a person who was born in January or early February has the sign of the previous year. For example, if a person was born in January 1970, his or her element would still be Yin Earth, not Yang Metal. Similarly, although 1990 was called the year of the horse, anyone born from January 1 to January 26, 1990 was in fact born in the Year of the Snake (the sign of the previous year), because the 1990 Year of the Horse did not begin until January 27, 1990. For this reason, many online sign calculators (and Chinese restaurant placemats) will give a person the wrong sign if he/she was born in January or early February.

The start of a new Zodiac is also celebrated on Chinese New Year along with many other customs.


Five elements

The Yin or Yang is broken down into Five Elements (Wood, Fire, Earth, Metal, and Water) on top of the cycle of animals. These are modifiers and affect the characteristics of each of the 12 animal signs. Thus, each of the 12 animals are governed by an element plus a Yin Yang Direction.

Although it is usually translated as 'element' the Chinese word xing literally means something like 'changing states of being', 'permutations' or 'metamorphoses of being'. [1] In fact Sinologists cannot agree on one single translation. The Chinese conception of 'element' is therefore quite different to the Western one. The Western elements were seen as the basic building blocks of matter. The Chinese 'elements', by contrast, were seen as ever changing and moving forces or energies - one translation of xing is simply 'the five changes'.

The balance of yin and yang and the five elements in a person's make-up has a major bearing on what is beneficial and effective for them in terms of feng shui, the Chinese form of geomancy. This is because each element is linked to a particular direction and season, and their different kinds of qì or life force.

The 12 zodiac animals

In Chinese astrology the zodiac of twelve animal signs represents twelve different types of personality. The zodiac traditionally begins with the sign of the Rat, and there are many stories about the Origins of the Chinese Zodiac which explain why this is so (see below). The following are the twelve zodiac signs in order and their characteristics.

Can be naive, over-reliant, self-indulgent, gullible, fatalistic, materialistic.

In Chinese astrology the animal signs assigned by year represent what others perceive you as being or how you present yourself. It is a common misconception that the animals assigned by year are the only signs, and many western descriptions of Chinese astrology draw solely on this system. In fact, there are also animal signs assigned by month (called inner animals) and hours of the day (called secret animals).

To sum it up, while a person might appear to be a dragon because they were born in the year of the dragon, they might also be a snake internally and an ox secretively. In total, this makes for 8,640 possible combinations (five elements x 12 animals in the 60 year cycle (12 x 5 = 60) , 12 months, 12 times of day) that a person might be. These are all considered critical for the proper use of Chinese astrology.

The months - the inner animals

The 12 animals are also linked to the traditional Chinese agricultural calendar, which runs alongside the better known lunar calendar. Instead of months, this calendar is divided into 24 two week segments known as Solar Terms. Each animal is linked to two of these solar terms for a period similar to the Western month. Unlike the 60 year lunar calendar, which can vary by as much as a month in relation to the Western calendar, the agricultural calendar varies by only one day, beginning on the Western February 3rd or 4th every year. Again unlike the cycle of the lunar years, which begins with the Rat, the agricultural calendar begins with the Tiger as it is the first animal of spring.

An individual's monthly animal sign is called their inner animal and is concerned with what motivates a person. Since this sign dictates the person's love life and inner persona, it is critical to a proper understanding of the individual's compatibility with other signs.

As each sign is linked to a month of the solar year, it is thereby also linked to a season. Each of the elements is also linked to a season, and the element that shares a season with a sign is known as that sign's fixed element. In other words, that element is believed to impart some of its characteristics to the sign concerned. The fixed element of each sign applies also to the year and hour signs, and not just the monthly sign. It is important to note that the fixed element is separate from the cycle of elements which interact with the signs in the 60 year cycle.

The hours - the secret animals

The Chinese zodiac is also used to label times of day, with each sign corresponding to a "large-hour" or shichen (時辰), which is a two-hour period (24 divided by 12 animals). It is therefore important to know the exact time of birth to determine it. The secret animal is thought to be a person’s truest representation, since this animal is determined by the smallest denominator: a person’s birth hour. As this sign is based on the position of the sun in the sky and not the time of your local clock, it is important to compensate for daylight savings time. However, some online systems already compensate for daylight savings time, and astrologers may compensate your time for you oblivious to the fact that you've compensated it yourself, leading to an inaccurate reading.

The large-hour in which a person is born is their secret animal. It is a person's own true sign which their personality is based on. Note that while this chart is quite accurate, the exact time at which each animal begins shifts by the day.

Categorizations of the twelve signs

Power Signs: Rat, Ox, Tiger, Dragon, Snake, Monkey

Romance Signs: Rabbit, Horse, Sheep, Rooster, Dog, Pig


The Four Animal Trines

The First Trine

The first trine consists of the Rat, Dragon, and Monkey. These three signs are intense and powerful individuals, capable of great good or great evil. They make great leaders, but the three have different approaches. Rats and Dragons have a tendency to be quite dictatorial and autocratic, whilst Monkeys are more diplomatic. Frustrated when hampered, these signs are ruled by highly potent energy and unpredictability. They are intelligent, magnanimous, charismatic, charming, authoritative, confident, eloquent and artistic. They can also be tyrannical, bombastic, prejudiced, deceitful, imperious, ruthless, power-hungry, and megalomaniacal.

The Second Trine

The second trine consists of the Ox, Snake, and Rooster. These three soul mates conquer life through endurance, application, and slow accumulation of energy. Although each sign is fixed and rigid in opinions and views, they are genius in the art of meticulous planning. They are hardworking, discreet, modest, industrious, charitable, loyal, punctual, philosophical, patient, and good-hearted individuals with high moral standards. They can also be self-righteous, vain, critical, judgmental, unimaginative, narrow-minded, petty, and pessimistic

The Third Trine

The third trine consists of the Tiger, Horse, and Dog. These three signs seek a true lover, and are like-minded in their pursuit of humanitarian causes. Each is a gifted orator and excels at verbal communication. Relationships and personal contact are of highest priority and each one seeks their intimate soul mate. Idealistic and impulsive, the Tiger, Horse and Dog follow the beat of their own drummer. Defiant against injustice, these three signs wilt without large amounts of physical affection and loyal support for causes. They are productive, enthusiastic, independent, engaging, dynamic, and honourable. They can also be rash, rebellious, quarrelsome, hot-headed, reckless, anxious, moody, disagreeable, and stubborn. Although these three signs are loyal, they can be very protective when lied to. The three signs do not enjoy being told what to do, but will listen when it is a person they love or trust whole-heartedly

The Fourth Trine

The fourth trine consists of the Rabbit, Sheep, and Pig. The quest for these three signs is the aesthetic and beautiful in life. Their calm nature gives them great leadership abilities. They are artistic, refined, intuitive, and well-mannered. These souls love the preliminaries in love, and are fine artists in their lovemaking. The Rabbit, Sheep and Pig have been bestowed with calmer natures than the other 9 signs. These three are compassionately aware, yet detached and resigned to their condition. They seek beauty and a sensitive lover. They are caring, unique, self-sacrificing, obliging, sensible, creative, emphatic, tactful, and prudent. They can also be naive, pedantic, insecure, cunning, indecisive, and pessimistic.


Zodiac origin stories

The 12 Zodiac animal signs (生肖 shengxiao) are, in order, the rat, ox, tiger, rabbit, dragon, snake, horse, sheep (ram or goat), monkey, rooster, dog, and pig. There are many legends to explain the beginning of the zodiac. One of the most popular reads, in summarized form, as follows:

The rat was given the task of inviting the animals to report to the Jade Emperor for a banquet to be selected for the zodiac signs. The cat was a good friend of the rat, but the rat tricked him into believing that the banquet was the next day. The cat slept through the banquet, thinking that it was the next day. When he found out, the cat vowed to be the rat's natural enemy for ages to come.

Interestingly, the cat does make it into the Vietnamese Zodiac, in place of the rabbit.

Another popular legend has it that a race was used to decide the animals to report to the Jade Emperor.

The cat and the rat were the worst swimmers in the animal kingdom. Although bad swimmers, they were both intelligent. They decided that the best and fastest way to cross the river was to hop on the back of the ox. The ox, being a naïve and good-natured animal, agreed to carry them across. However, overcome with a fierce competitiveness, the rat decided that in order to win, it must do something and promptly pushed the cat into the river. Because of this, the cat has never forgiven the rat, and hates the water as well. After the ox had crossed the river, the rat jumped ahead and reached the shore first, and it claimed first place in the competition.

Following closely behind was the strong ox, and it was named the 2nd animal in the zodiac. After the ox, came the tiger, panting, while explaining to the Emperor just how difficult it was to cross the river with the heavy currents pushing it downstream all the time. But with powerful strength, it made to shore and was named the 3rd animal in the cycle.

Suddenly, from a distance came a thumping sound, and the rabbit arrived. It explained how it crossed the river: by jumping from one stone to another in a nimble fashion. Halfway through, it almost lost the race but the rabbit was lucky enough to grab hold of a floating log that later washed him to shore. For that, it became the 4th animal in the zodiac cycle. Coming in 5th place was the dragon, flying and belching fire into the air. Of course, the Emperor was deeply curious as to why a strong and flying creature such as the dragon should fail to reach first. The mighty dragon explained that he had to stop and make rain to help all the people and creatures of the earth, and therefore he was held back a little. Then, on his way to the finish line, he saw a little helpless rabbit clinging on to a log so he did a good deed and gave a puff of breath to the poor creature so that it could land on the shore. The Emperor was very pleased with the actions of the dragon, and he was added into the zodiac cycle. As soon as he had done so, a galloping sound was heard, and the horse appeared. Hidden on the horse's hoof is the snake, whose sudden appearance gave the horse a fright, thus making it fall back and gave the snake 6th spot while the horse took the 7th.

Not long after that, a little distance away, the ram, monkey and rooster came to the shore. These three creatures helped each other to get to where they are. The rooster spotted a raft, and took the other two animals with it. Together, the ram and the monkey cleared the weeds, tugged and pulled and finally got the raft to the shore. Because of their combined efforts, the Emperor was very pleased and promptly named the ram as the 8th creature, the monkey as the 9th, and the rooster the 10th.

The 11th animal is the dog. His explanation for being late—although he was supposed to be the best swimmer amongst the rest—was that he needed a good bath after a long spell, and the fresh water from the river was too big a temptation. For that, he almost didn't make it to finish line. Just as the Emperor was about to call it a day, an oink and squeal was heard from a little pig. The pig got hungry during the race, promptly stopped for a feast and then fell asleep. After the nap, the pig continued the race and was named the 12th and last animal of the zodiac cycle. The cat finished too late (thirteenth) to win any place in the calendar, and vowed to be the enemy of the rat forevermore.


Chinese zodiac in other countries

The Chinese zodiac is also used in some other Asian countries that have been under the cultural influence of China. However, some of the animals in the Zodiac may differ by country.

East Asia

For example, the Vietnamese zodiac is almost identical to Chinese zodiac except that the second animal is the water buffalo instead of the ox, the fourth animal is the cat instead of the rabbit and the eighth animal is the goat instead of the sheep. The Japanese zodiac includes the wild boar instead of the pig, and the Thai zodiac includes a naga in place of the dragon.
