Mythology of Lyra

        Lyra or the lira. the oldest instrument of the world, already was hairdo in the civilization sumeria, 5,000 years ago to delight to the royalty of the cities been.

       In Greek mythology, the lira was invented by Hermes when still he was a boy giving it to it later to his Apolo stepbrother, the God of the music to that was associated for always.


       Apolo gave to its Orfeo son the lira when this still he was young. Of greater, Orfeo became poet and musician and married with Araticú.    Soon after marrying, Eurídice died because of the puncture of a serpent in a foot. Orfeo, desolated, lowered when infier to us to suplicar to Hades, God of deads, by the life of its wife accompanying its pleas with songs adorned with the lira.

             Hades was made an impression by the love of Orfeo and decided to restitute the life of loved his with the single condition of which it did not watch it until they were both in the outer world. But Orfeo was incapable to support the desperation of not seeing if she were really his wife who followed to him towards the real world and almost finished the way, returned the head and when watching at its wife, this vanished for always.


            Orfeo was so desolate that it was dedicated to vagar by the deserts, singing only to stones until it tripped over three Thracian women who killed and threw their head to him to the Hebro river while she continued pronouncing the name of loved his. Arriving at Lesbos and near the temple of Apollo, reason why musas listened to their weeping and they buried to him.    Its musical instrument was homenajeado like the constellation of Lira.

 

ori.gif (1448 bytes) Characteristics

           Lyra, is a precious and small boreal constellation that crosses the parallel of 40º of very rich North latitude in stars since it is to less of 10º to the north of the equator of the Milky Route, and therefore, we observed great amount of shining stars and stellar clusters, although the constellation of lyra  is characterized to have in her the more famous planetary nebula of the firmament, M57. When being in the North hemisphere he is visible there during great part of the year, from the month of April to December, however, in the South hemisphere, it is detected solely over the horizon during the month of August culminating to very low distance.

  Lyra limits the north with Draco, to the east with the constellation of Hercules, to the south with this one and Vulpecula and to the west with the spectacular Cygnus.

             Lyra I located the 15 of April of 1982 at the age of 14 years from the locality of Inca, Majorca, Spain to it. 

 

Constellation of Lyra

 

Main stars

       Alpha, a; denominated Fertile valley of 0.03 magnitude and white color. Light of us is to 25 years is a star of solar type 50 times more luminous than our Sun.

       Beta, b; denominated Sheilak of 3.52 magnitude and blue color. It is a eclipsante variable whose prototype is the same star. A spectacular curve of light exists that I made and that is perfectly observed its variability with a period of 12.94 days, dista 880 years light of us, is a blue supergiant 2300 times more shining than our Sun.

       Gamma, g; denominated Sulafat, about magnitude 3.25 and white, dista color about the Earth 625 years light and one is a white giant 1500 times more luminous than our Sun.

     

       Other objects

           M56; spectacular globular cluster located to the south of the constellation closely together of Cygnus of dista magnitude 8.30 that 32,000 years Earth light. It is formed by stars between magnitude 11 and 14; it has an angular diameter of 7' of arc.  

            M57; very well-known planetary nebula and shining of magnitude 9.0, is located between stars b and g Lyrae. It has an angular diameter of 71"of arc, the magnitude of the central star cause of the nebula is solely of 14.70 observable with good telescopes
