Ophiuchus (Serpent Holder)

is one of the signs of the Zodiac in sidereal astrology since 2011, includes the period between November 30th to December 17th.
Located between the signs of Scorpio and Sagittarius, tha IAU –International Astronomical Union- fiexed its position as a constellation en zodiacal line in 1930, though it is not openly acknowledged by Babilonian base astrology.
In 2011, Ophiuchus zodiacal status debate was revived given to the declarations of Parke Kunkle, from Minnesota Planetarium Society.
In Greek mythology, Ophiuchus correspond to Asclepius, son of Apollo and the human Coronis. He developed such skills in medicine, stating that he could even raise the dead. Insulted, Hades asked Zeus to kill him for violating the natural order of things, to which Zeus agreed. However, as a tribute of his worth, Zeus decided to place him in the sky surrounded by the serpent as a symbol of renewed life.
Its symbol is the rod of Asclepius, which is also medicine’s in west.

It is located in the sky very close to the core of Milky Way and in the opposite area to Orion. It is easily observable from April to October in both hemispheres.
The thing about Ophiuchus is that the ecliptic crosses the constellation by the south during the first half of December, therefore, it is actually a zodiac constellation but not acknowledged as such given his south limit was initially assigned to Scorpius. In addition, the entire constellation is approximately 10° north to the galactic equator, so we can see a large number of stars and star clusters.
Ophiuchus limits to the north with Serpens, Libra and Scorpius; to the west with Sagittarius, Aquila and again Serpens. Finally to the south with Hercules.
It has many important nebulae, as: M10, M12, M14, M107 and M9.
