constellation Canis Major, and especially its main star - Sirius, known to people since ancient times.This is not surprising, given that Sirius is a true "light" of the sky: it is second only to the apparent brightness of the sun, moon and three other planets of the solar system - Mars, Venus and Jupiter.In addition, the star Sirius in the sky visible from virtually any point on our planet, making the well-known constellations and stars.
According to scientific data, Sirius - is the alpha constellation Canis Major.Remove from our system is "only" 8.6 light years, making it one of the closest to us.Interestingly, the star Sirius is double or even triple (although the existence of the third component is not proven).Accordingly, the striking element - Sirius A (alpha), while the second component - a white dwarf Sirius B. Full rotation is about a common center for 50 years.Initially, the mass of Sirius A is equal to 2 solar masses, but Sirius B was a massive, accounting for nearly 5 solar masses.Subsequently, the last state before the collapse of a white dwarf (high-density material, a relatively small diameter and temperature).
star Sirius B was opened in 1862 by indirect observations: fixed distortions in the movement of the second component (alpha) caused by the pull of a massive dark satellite.The calculations have allowed her to discover herself.Sirius, there are at least 200 million. Years.All the parameters of the star can be found in the relevant literature.
What is so interesting constellation?Sirius is mentioned in many cultures, separated by centuries.Even the ancient Dogon knew about the star.For example, the well known lines from the Bible, in which the wise men, who appeared to the unborn Jesus is reported that has led them to a bright star in the east.Also, many people who practice channeling claim that the Alpha Canis inhabited, and there are living beings highly, seeking to help humanity.
particularly known Sirius acquired through the research of the Egyptian pyramids.Some mines are focused strictly on the star, in addition, there are a lot of assumptions, according to which pyramids themselves were built by aliens.Like it or not, time will tell, however, it is known that Sirius has played an important role in the life of ancient Egypt.So, at the beginning of the season of his morning appearance in the sky it coincided with the flood of the river Nile.Although because of this star idolized, nothing improbable in fact was not.The beginning of summer caused rapid melting of mountain snow in Ethiopia, the strong equatorial rainfall and, as a consequence, increase the level of water and pour into a fertile plain.After its descent could begin the necessary agricultural work.
Despite the "closest" location, Sirius is still poorly known.Even his second major component was detected indirectly because of the distortions in the path of movement of Sirius A. Accordingly, the observation about the planetary system is not out of the question.Therefore, it is not known whether there is life in the system.What is strange, all the ancient philosophers (eg, Ptolemy, Seneca) called Sirius red star, although its bluish glow.Red could be explained by the presence in the red giant, as the white dwarf Sirius B is really not passed this stage.However, it is believed that the red giant stage and discharge shells had passed 120 million. Years ago, and philosophers lived in the beginning of our era.The paradox is obvious.
Without a doubt, Alpha Canis conceals many mysteries to be solved for future generations.In the sky there are not many facilities that were worshiped by ancient cultures, but Sirius - the brightest (in all senses) their representative.
