Mitología de Aries

     Aries are a constellation that has been enjoying unquestionable an historical prestige, since it is related to one of the most beautiful mythical legend, or because in her, for twenty centuries, the Sun appeared annually from the low zones of the austral hemisphere to return to broadcast and to fertilize the populations of the first human civilizations. In Aries it was the equinoccial point of spring, that is to say, the ascending node of the ecliptic, that established the beginning of the spring with the ceremonies propiciatorias the ancient sacrum. Therefore, it was considered to Aries like the first house that occupied the Sun in its annual way, & perhaps due to these characteristics so peculiar hers, the Egyptians consecrated the fabulous Fénix to him, the legendary bird of gilded wings & red, to similarity of the star of the day, he resurged perennially of his own ashes.

      The astrologers feared particularly Aries because he denoted violent & passional temperament for which they had been born under his sign and, which was more terrible, eras messenger of damage and epidemics if it appeared in him some comet. What it really is today is that no longer is high-priority Aries as sign of the zodiacal constellations since the progressive   displacement of the equinoccial point throughout the ecliptic, because of the precession of the terrestrial axis, has if, in more than 20 centuries, the zodiacal signs move more of 30º respect to the corresponding constellations, as much that, in our time, the spring equinox already is located in the constellation of Piscis and therefore, the Sun reaches a month before to Aries. We do not have left the reverencial fear that knew to inspire by the simple and superstitious souls of the old ones, nor either dominate a zone of ample and enviable the sky, since the limits of Aries single cover 440 square degrees with the firmament.

       The star most shining of Aries, a arietis of second magnitude has like name to Hamal or head of the sheep, is a giant star that stands out more within the celestial desert of the zone, seems to be that many temples of the antiquity were oriented towards her, specially the dedicated ones to Zeus & his Athenian divine daughter.

    Aries are a zodiacal constellation located in the North hemisphere between the zodiacal constellations of Piscis & Taurus, the Sun crosses this constellation from end of April & principles of May. The ecliptic crosses Aries by the low part of the constellation next to the constellation of Cetus. One is a small constellation of about 400 square degrees. Visible in the North hemisphere and until 70º of South latitude that crosses the meridian in the nights of October.

   It limits the north with Andromeda & Triangulum, the east with Piscis, the south with Cetus & the west with Taurus. One is to 40º of South latitude of the equator of the Milky Way and therefore, in a zone of the poor sky in stars, stellar and globular accumulations, and something richer in galaxies. They are easy to recognize the star & b Arietis & the star 41 that comprise the asterism of the constellation, if this line is followed takes us to the stellar accumulation of the Pleiads in the constellation of Taurus, therefore, is easier their identification.

   The constellation of Aries I located the January 22nd, 1982 at the age of 15 years-old.

 

Constelación de Aries

 

Main stars

       Alpha, a ; also Hamal call or head of sheep. It is a red giant of magnitude 2,00, 70 times more luminous than our Sun; it seems to be that many temples of the antiquity were oriented towards her. It's to 65 years-light of us.

      Beta, b ; it has a magnitude of 2,64, of white color one is to 60 years light of us, also Sharatan call , is a spectrocopical binary, therefore, the secondary one is detectable solely by the variability of b , that it orbits in a period of 107 days. b varies between magnitudes 2,56 & 2,70 in a variable irregular period of the type d Scutum.  

     Gamma, g; it is one of double stars prettier than I have seen, was discovered by chance by Robert Hooke in 1664, the main star is of magnitude 4,70 & white color & secondary of identical magnitude & color, visible ones with any telescope it's at the moment separated 8 of second arc. The orbital system is to 204 years light of us.

    41; one is the last star of the asterism of the sheep located already next to Taurus, is a blue star of magnitude 3.61 that is to 160 years light of us, and was born and one formed in the stellar nebula of the Pleiads.
