Mythology

The Romans came up with the idea of the goddess fish in the myth of Venus and her son Cupid. These two mythic figures were surprised by the monster Tifon, but Venus knew that they could escape by water. Caught Cupid and immersed himself in the water, the both were transformed into fish. To make sure that not be lost, were tied with a rope. In the sky we see, therefore, to both mother and child, which are united by a rope.

Pisces, the 12th zodiacal constellation, it is difficult to locate because the stars that compose it are very faint; none of them exceeds the magnitude 4. The figure consists of two fish tied by their tails with a rope; the fish eastern swims in the vertical direction, while your partner is oriented toward the west and located just a few degrees above the equator, more or less parallel to this. A ring of five stars, which in some occasions, they have received the name of the wheel, is located immediately south of the great Square of Pegasus, and to the south, but slightly to the east of the bright star Markab. The head of the fish, that swims, toward the north is about to collide with Andromeda, and it is easy to find it exactly to the south of Mirach. In the eastern end of this constellation, the rope that binds the fish is indicated by the star Alrischa. Pisces has its peak between the end of September and principles of October.

To frighten the monster, Pan issued a squeal, which allowed Hermes (the messenger of the gods) recover the members torn from Zeus. Together, Pan and Hermes have been reassembled to Zeus that he rewarded Pan by assigning it a place among the constellations.

Capricorn, the tenth and the smallest of the zodiacal constellations, is formed by stars of magnitude 3 and 4, located to the east of Sagittarius. Its height is given at the beginning of August, but the combination of clear skies and its location at the south of the equator make this constellation is appreciated very little since middle and high latitudes in the northern hemisphere. You can locate by drawing a line from Vega (constellation Lira) that pass by Altair (from the constellation of the Eagle) going through the Milky Way, until you reach Algedi and Dabih, which are the stars alpha and beta of the horns of the goat.

In addition, the center of our Milky Way galaxy is in the southeast of the same, the Milky Way's nucleus is located 30,000 light years from the Sun, therefore, if we look to this constellation, thanks to its proximity to the center of the galaxy, we can get to see your kernel and a large quantity of clusters and tasty fields of stars.

This is the scorpion, who is represented in the sky of summer. Orion shines in the nights of winter and its brightness wanes when it arises the constellation Scorpius. That is why competition develops between Scorpio and Orion.

The balance symbolized the identical duration of the day and night in the equinoxes: two millenniums ago, the passage of Sun to Pound marked the equinox of September. Were the roman’s astrologers who interpreted the scales of Libra as justice, subject by Astrea, the goddess of justice.

Libra is the seventh sign of the zodiac, is situated between Virgo to the west and Scorpio, to the east. Due to its low visual charm, it is easier identification from Scorpio. To do this we will have to extend the claws of the scorpion to form a few large claws. The tip of the scales, Zuben Elgenubi is almost exactly on the ecliptic, half way and a few degrees north of a line that extends between Spica (Virgo) and Antares (Scorpio). Pound has its peak at the beginning of may; you can see it from all latitudes except from the arctic region.

As a result of the rapture, the mother of persephone, Demeter destroyed all the crops. This situation forced the great gods to let her in freedom.

Virgo is the sixth zodiacal constellation and the second constellation, after Hydra in terms of surface área. However, with the exception of its brightest star, Spica, the rest has very light definition. Is represented by the figure of a winged girl superimposed on the ecuador, for the most part north of the ecliptic, although Spica, a star that indicates the position of the ecliptic. In the southern hemisphere, Virgo is a constellation of autumn, which is situated to the north of the Centaur

After fighting with the lion with his bare hands and after having drowned up to kill him, Hercules use the claws of the lion for tails. With the skin is made a layer that the toward invulnerable; and with the head of the animal, a helmet.

Leo is the fifth zodiacal constellation, as well as the most easily recognized in the sky: a lion crouched looking toward the west, whose head and mane are very visible thanks to the sickle stars similar to a question invested, which draws a curve to the north of Regulus (cc Leo). The constellation Leo is located just south of the stars "indicator" of the ladle, and to the northwest of Virgo. Its peak takes place at the beginning of March.

Cancer

Mythology
According to an ancient Greek legend, the figure of a crab was placed in the night sky by the goddess Hera to form the constellation of Cancer. Hera promised to kill Heracles, the most famous Greek hero. She tried to kill Heracles in many different ways, but each time his incredible physical strength allowed him to survive. Hera cast a spell from the madness of Heracles, which makes him commit a great crime. In order to be forgiven, he had to perform twelve difficult tasks. One of these tasks was to destroy the terrible nine-headed water-serpent Hydra.
During the battle between Heracles and the Hydra, the goddess Hera sent a crab to help the snake. But Heracles, being so strong, killed the crab by smashing his shell with his foot. As a reward for their services, Hera placed the crab's image in the night sky.

The fixed stars of Cancer the past had marked the position of the sun in the June solstice. To the Mesopotamians, this key position marked the portal through which souls descend from the incarnation. This analogy is very similar to the Egyptian tradition, in which the constellation of Cancer was the sun god Khepri, celestial personification of the scarab, symbol of fertility, life and rebirth.

Cancer is one of the constellations of the zodiac signs are not very visible, in fact, a constellation that is hard to see unless you have a light pollution of the sky clear and no moon, much more.
This constellation has its culmination in the North hemisphere in late January and early February, soon to be easier to see.

When Castor was killed by the spear of Idas, Pollux, after revenge, asked Zeus to give immortality to his brother, and since both brothers are in the sky the constellation Gemini.

Gemini, visible during the fall and winter in the North hemisphere and the south hemisphere summer.
The constellation is crossed by the parallel 30 °, to observe for the first time emphasizes his two brightest stars Castor and Pollux of almost identical magnitude. Gemini is in an area full of stars in our galaxy, the Milky Way, the constellation crosses the eastern sector, therefore, we observe many double stars and clusters of bright stars and variables.
Gemini is a zodiacal constellation, that is, the ecliptic or imaginary line that moves the sun and now eight planets, constellation crosses from east to west the sun remained there for more than thirty days from the end of June the first half of July.

The position of Taurus, near the Ecuador sky, allows observation from anywhere in the world, except from an Antarctic region, which partially obscures. From the northern hemisphere winter in the tropics, is shown in its most magnificent.
Its height is between late November and early December. And I recommend to seethis constellation if we could with binoculars, because wherever you look has nowaste.
