History ...

In astronomy, the zodiac (from Greek "zoon-Diak" meaning wheel animals) is a band that encircles the celestial sphere to the ecliptic and understanding that is wide enough to contain the Sun comprises 13-14 constellations.
In astrology, the zodiac is based on the division into twelve equal parts of the celestial band on which trace their paths the Sun, Moon, and planets, moving a section for each month of the year. Each sector contains the traditional constellation to which it owes its name. The Babylonians and Greeks divided this band into twelve equal parts, each of them a patch of sky for an extension of thirty degrees of arc, christened with the name of the twelve most prominent constellations they saw in each of the subdivisions. The zodiac has a fundamental importance in Western astrology. Other cultures such as Chinese astrological tradition also give particular importance to this region of the sky, although defines a different zodiac.


The relative position of the Sun with respect to the constellations of the zodiac at the time of a person's birth determines your astrological sign. The zodiac signs are determined by their position on the vernal point (Point Gamma, which is the 0 degree Aries) or intersection of the plane of the ecliptic with the plane of Ecuador Celeste, not by its position relative to the constellations, as usually given.
The constellations are groups of a few stars that man has given way to name and locate in the sky and appear to be fixed in the sky. The ecliptic is the plane in which Earth moves about the Sun, is especially important for astrology. There are the twelve constellations of the "fixed stars".

How and when to locate the constellations

Find constellations is a stimulus for any beginner, and we've allbeen through it as an adventure and the challenge of the dark skyabove us that we have for any night. The key is to identify the brightest and then jump from star to star as the addresses youhave and set out on this page. Let's start with the challenge
Focus on the sky can be quite daunting at first because of the difficulty in locating start forms and shapes, but in reality it is more difficult to read a road map and a small dose of relaxation. The stars on any night seem to wander slowly through the sky, and also tomorrow night resemble the same. But how to find the way to a point in a sky so vast and crowded with stars? Very easy, areference star and then jump from one star to another.


For people in the northern hemisphere sky has a bright star near the north celestial pole, which is a good place to start.

In the southern hemisphere we place Sagittarius which is located south of Eagle.
Immediately south of Ophiuchus is Scorpio, with its bright red star
Antares and the sharp sting under the right foot of this giant. West of
Scorpion is Libra, to which the ancients designated the name of
Claws of the Scorpion. Continuing westward from Libra, we get the
Virgo constellation with the star Spica.
Another asterism that attracts the viewer's attention when he contemplates
the sky in the months leading up to December is a grouping of three
stars in a straight line. These stars represent Orion's belt. about
10 ° north of Orion's belt we have the bright red star
Betelgeuse, and about 10 ° south of the same belt is perceived bluish star
Rigel. If we follow the line marked by the belt of Orion to the east (or
left when the observer is oriented to the south) will be found
blue-white star Sirius, the brightest in the sky.
To the west of the belt of Orion to find the bright red star
Aldebaran in the constellation Taurus, and a little further west
will reach the open cluster M45 and the Pleiades. Procyon, Sirius (Sirius)
and Betelgeuse form a triangle. But the winter is called Hexagon
are the following stars: Procyon, Pollux, Castor, Capella, Aldebaran,
Rigel and Sirius.

Names...

Zodiac name comes from the fact that most of these constellations are named after animals, deriving the word from the Greek zodiac zoon ("animal").
Isaac Newton proposed the theory that the twelve names of the ancient zodiacal constellations paid homage to the myth of Jason and the Argonauts and their journey towards the golden fleece. So Aries fleece refers to himself, Leo the hero Heracles (Roman Hercules), wearing lion skin Cithaeron, Gemini the twins Castor and Pollux, Virgo the priestess of the temple where they guarded the fleece, and so on.

Aries: The Ram with whom traveled Frixio and Hele, when they left their homeland to reach Colchis. It was then the Golden Fleece.

Taurus: There are two versions 1) The Bull of Crete, a mythical beast that lived in that area. 2) The form adopted when Zeus kidnapped Europe.

Gemini: twins Castor and Pollux. Pollux was immortal, and his brother Castor. When Castor died, Pollux gave his immortality to save his brother.

Cancer: crab that Hera sent to help the Hydra of Lerna, when it fought against Hercules.

Leo: The Lion of Nemea, killed by Hercules, who strangled him, because his skin was impenetrable. The hero with his own claws skinned (the one that could hurt him) and stayed skin as its symbol.

Virgo: The myth is Astraea, daughter titánide CEO and Phoebe, still having had an affair with fellow Titan Perses, whose union was the result of Hecate (Goddess of Darkness and the Crossroads), virtuously resisted the ravings of Zeus not to become another adventure carnal "thunder." Because of this island was turned into an almost deserted and abandoned, Ortigia.

Libra: Myth says that is attributed to the goddess of Justice, as well as illustrating ancient Roman depictions of Julius Caesar carrying a balance, symbolizing his power and justice. Later the Roman ruler would be deleted and the figure would keep the balance.

Scorpio: Scorpio the goddess Artemis sent the giant hunter Orion. As Orion was a little short of mind, stepped and drove the scorpion sting. Both died and Zeus placed opposite each other, so they do not would fight.

Sagittarius: The Centaur Chiron, medical doctors, tired of his immortal status, decided to change it for the salvation of Prometheus. When the deal was finalized, Prometheus asked "Why did you do that? Now you're dead, much as you tire, you will not be able to change ..."
Ophiuchus: God of the stick and the serpent, known in other mythologies, currently number 13 zodiac sign, due to the precision of merit the motion of the earth's axis.

Capricorn: Representation of the goat Amalthea, which suckled Zeus when his mother Rhea hid him from sight of his father Cronos.

Aquarius: The young Ganymede, the cupbearer of the gods on Olympus. An extremely beautiful girl who got the love of the God Zeus.

Amazing! New sign

Ophiuchus reaches the horoscope as a new sign of the zodiac and causes chaos
Fans go check daily horoscope disoriented by the news of the arrival of a new / old Star Sign: Ophiuchus. Many 'refuse' a change of sign (in the case that can be done) to the commotion caused by the new sign.

12, were 12. 12 as the apostles, 12 as the months, including 12 strokes and how many times the moon revolves around Earth, a fact vital to establish the signs of the Zodiac.
The número12 is the symbol of cosmic order. Or was it because the arrival of Ophiuchus has sent ordenadito how good we had it all to hell. Because if Ophiuchus is definitely established in the horoscope, the 12 signs were to become 13.
Unless you're a follower of Final Fantasy or a 'crack' of the stars, the name of Ophiuchus was rather unknown. The International Astronomical Union adopted its position as a zodiacal constellation in the line from 1930, but Ophiuchus was not recognized by traditional astrology, of Babylonian origin.
But everything has changed, or may change with the principles of the Minnesota Planetarium Society, which calls for Ophiuchus Star status.
Ophiuchus, also known as snake, corresponds in Greek mythology, Asclepius, the son of Apollo and Coronis human. It was as good healing the sick who said he could raise the dead, and he was killed by Zeus. Its symbol is the Rod of Asclepius (a snake entwined on a stick).
The fact is that the new sign of Ophiuchus has caused a huge stir and many fans to the designs of the stars 'refuse' a change of sign. Social networks (speaker and a reflection of what's happening in society) reflect the discomfort and embarrassment both anonymous users and large stars (like Katy Perry who still wonders if Scorpio ...)

With the inclusion of Ophiuchus, the zodiac would look like:

Capricorn: January 21 to February 16

Aquarius: February 17 to March 11

Pisces: March 12 to April 18

Aries: April 19 to May 13

Taurus: May 14 to June 21
