Zodiacs
The zodiac is a belt-shaped region of the sky that extends approximately 8° north or south (as measured in celestial latitude) of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets are within the belt of the zodiac. In Western astrology, and formerly astronomy, the zodiac is divided into twelve signs, each occupying 30° of celestial longitude and roughly corresponding to the following star constellations: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. These astrological signs form a celestial coordinate system, or more specifically an ecliptic coordinate system, which takes the ecliptic as the origin of latitude and the Sun's position at vernal equinox as the origin of longitude.

Astrological Sign
In Western astrology, astrological signs are the twelve 30-degree sectors that make up Earth's 360-degree orbit around the Sun. The signs enumerate from the first day of spring, known as the First Point of Aries, which is the vernal equinox. The astrological signs are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. The Western zodiac originated in Babylonian astrology, and was later influenced by the Hellenistic culture. Each sign was named after a constellation the sun annually moved through while crossing the sky. This observation is emphasized in the simplified and popular sun sign astrology. Over the centuries, Western astrology's zodiacal divisions have shifted out of alignment with the constellations they were named after by axial precession of the Earth while Hindu astrology measurements correct for this shifting. Astrology (i.e. a system of omina based on celestial appearances) was developed in Chinese and Ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Astrology
Western astrology is the system of astrology most popular in Western countries. Western astrology is historically based on Ptolemy's ''Tetrabiblos'' (2nd century CE), which in turn was a continuation of Hellenistic astrology, Hellenistic and ultimately Babylonian astrology, Babylonian traditions. Western astrology is largely horoscopic astrology, horoscopic, that is, it is a form of divination based on the construction of a horoscope for an exact moment, such as a person's birth as well as location (since time zones may or may not affect a person's birth chart), in which various cosmic bodies are said to have an influence. Astrology in western popular culture is often reduced to sun sign astrology, which considers only the individual's date of birth (i.e. the "position of the Sun" at that date). Astrology is a pseudoscience and has consistently failed experimental and theoretical verification. Core principles A central principle of astrology is integration within the cosmos. T ...

Equinox (celestial Coordinates)
In astronomy, an equinox is either of two places on the celestial sphere at which the ecliptic intersects the celestial equator. Although there are two such intersections, the equinox associated with the Sun's ascending node is used as the conventional origin of celestial coordinate systems and referred to simply as "the equinox". In contrast to the common usage of spring/vernal and autumnal equinoxes, the celestial coordinate system equinox is a direction in space rather than a moment in time. In a cycle of about 25,800 years, the equinox moves westward with respect to the celestial sphere because of perturbing forces; therefore, in order to define a coordinate system, it is necessary to specify the date for which the equinox is chosen. This date should not be confused with the epoch. Astronomical objects show real movements such as orbital and proper motions, and the epoch defines the date for which the position of an object applies. Therefore, a complete specification of ...

Position Of The Sun
The position of the Sun in the sky is a function of both the time and the geographic location of observation on Earth's surface. As Earth orbits the Sun over the course of a year, the Sun appears to move with respect to the fixed stars on the celestial sphere, along a circular path called the ecliptic. Earth's rotation about its axis causes diurnal motion, so that the Sun appears to move across the sky in a Sun path that depends on the observer's geographic latitude. The time when the Sun transits the observer's meridian depends on the geographic longitude. To find the Sun's position for a given location at a given time, one may therefore proceed in three steps as follows: # calculate the Sun's position in the ecliptic coordinate system, # convert to the equatorial coordinate system, and # convert to the horizontal coordinate system, for the observer's local time and location. This is the coordinate system normally used to calculate the position of the Sun in terms of solar zen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecliptic Coordinate System
The ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations of Solar System objects. Because most planets (except Mercury) and many small Solar System bodies have orbits with only slight inclinations to the ecliptic, using it as the fundamental plane is convenient. The system's origin can be the center of either the Sun or Earth, its primary direction is towards the vernal (March) equinox, and it has a right-hand convention. It may be implemented in spherical or rectangular coordinates. Primary direction The celestial equator and the ecliptic are slowly moving due to perturbing forces on the Earth, therefore the orientation of the primary direction, their intersection at the Northern Hemisphere vernal equinox, is not quite fixed. A slow motion of Earth's axis, precession, causes a slow, continuous turning of the coordinate system westward about the poles of the ecliptic, completi ...

Celestial Coordinate System
Astronomical coordinate systems are organized arrangements for specifying positions of satellites, planets, stars, galaxies, and other celestial objects relative to physical reference points available to a situated observer (e.g. the true horizon and north cardinal direction to an observer situated on the Earth's surface). Coordinate systems in astronomy can specify an object's position in three-dimensional space or plot merely its direction on a celestial sphere, if the object's distance is unknown or trivial. Spherical coordinates, projected on the celestial sphere, are analogous to the geographic coordinate system used on the surface of Earth. These differ in their choice of fundamental plane, which divides the celestial sphere into two equal hemispheres along a great circle. Rectangular coordinates, in appropriate units, have the same fundamental () plane and primary (-axis) direction, such as a rotation axis. Each coordinate system is named after its choice of fundamental ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constellations
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object. The origins of the earliest constellations likely go back to prehistory. People used them to relate stories of their beliefs, experiences, creation, or mythology. Different cultures and countries adopted their own constellations, some of which lasted into the early 20th century before today's constellations were internationally recognized. The recognition of constellations has changed significantly over time. Many changed in size or shape. Some became popular, only to drop into obscurity. Some were limited to a single culture or nation. The 48 traditional Western constellations are Greek. They are given in Aratus' work ''Phenomena'' and Ptolemy's '' Almagest'', though their origin probably predates these works by several centuries. Constellations in the far southern sky were adde ...

Virgo (astrology)
Virgo () (Greek: Παρθένος, ''Parthenos'') is the sixth astrological sign in the zodiac. It spans the 150–180th degree of the zodiac. Under the tropical zodiac, the Sun transits this area, on average, between August 23 and September 22. Depending on the system of astrology, individuals born during these dates may be called ''Virgos'' or ''Virgoans.'' The sign is associated with Astraea. In Greek mythology, Astraea was the last immortal to abandon Earth at the end of the Silver Age. This was when the gods fled to Olympus – hence the sign's association with Earth. She became the constellation of Virgo. Virgo is one of the three Earth signs, along with Capricorn and Taurus. Origins The constellation Virgo has different origins depending on mythology. Most myths view Virgo as a virgin maiden with associations with wheat. In Greek and Roman mythology, the constellation is related to Demeter, the Greek goddess of the harvest, or her daughter Persephone, queen of t ...

Pisces (astrology)
Pisces () (; grc, Ἰχθύες ''Ikhthyes'') is the twelfth and final astrological sign in the zodiac. It is a negative, mutable sign. It spans 330° to 360° of celestial longitude. Under the tropical zodiac, the sun transits this area between February 19 and March 20. In classical interpretations, the symbol of the fish is derived from the ichthyocentaurs, who aided Aphrodite when she was born from the sea. According to some tropical astrologers, the current astrological age is the Age of Pisces,Nicholas Campion, (1988) ''The Book of World Horoscopes'' Aquarian Press, Wellingborough while others maintain that currently it is the Age of Aquarius. Background While the astrological sign Pisces per definition runs from ecliptic longitude 330° to 0°, this position is now mostly covered by the constellation of Aquarius due to the precession from when the constellation and the sign coincided. Today, the First Point of Aries, or the vernal equinox, is in the Pisces conste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latinisation Of Names
Latinisation (or Latinization) of names, also known as onomastic Latinisation, is the practice of rendering a ''non''-Latin name in a Latin style. It is commonly found with historical proper names, including personal names and toponyms, and in the standard binomial nomenclature of the life sciences. It goes further than romanisation, which is the transliteration of a word to the Latin alphabet from another script (e.g. Cyrillic). For authors writing in Latin, this change allows the name to function grammatically in a sentence through declension. In a scientific context, the main purpose of Latinisation may be to produce a name which is internationally consistent. Latinisation may be carried out by: * transforming the name into Latin sounds (e.g. for ), or * adding Latinate suffixes to the end of a name (e.g. for '' Meibom),'' or * translating a name with a specific meaning into Latin (e.g. for Italian ; both mean 'hunter'), or * choosing a new name based on some attribut ...

Aquarius (astrology)
Aquarius () is the eleventh astrological sign in the zodiac, originating from the Aquarius (constellation), constellation Aquarius. Under the tropical zodiac, the Sun is in the Aquarius sign between about January 20 and about February 18. Myth The water carrier represented by the zodiacal constellation Aquarius is Ganymede (mythology), Ganymede, a beautiful Phrygian youth. Ganymede was the son of Tros, king of Troy (according to Lucian, he was also the son of Dardanus). While tending to his father's flocks on Mount Ida, Ganymede was spotted by Zeus. The king of gods fell in love with him and flew down to the mountain in the form of a large bird, whisking Ganymede away to the heavens. Ever since, the boy has served as cupbearer to the gods. Ovid has Orpheus sing the tale. Constellation Aquarius is a winter constellation in the northern hemisphere, found near Pisces and Cetus. It is especially notable as the radiant for four meteor showers, the largest of which is the Souther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
