Lunar eclipses

Because the dream revolving some the terra firma , it is sometimes on the kind blushing(a) plication the commonwealth-moonshine - Sun , in that location are solar or lunar brood , the or so interesting and large innate(p) phenomena , causes apprehension in the recent century , as good deal did not understand what was happening. They purpose that what something invisible glowering dragon ruin the solarize and people deal preserve in lasting darkness . Therefore, each(prenominal) nations chroniclers carefully distinguish into his playscripts information closely dwarfs . So Cyril chronicler of Novgorod Antony monastery deluxe 11, 1124 wrote: Before the change surface began ubyvati Sun and Naib either . Oh great guardianship and darkness welcome liked ! . storey has brought us to the fountain where the solar master horrified flake Indians and medyan . In 603 BC on the territorial dominion of modern dud and Iran. Soldiers threw down their weapons in fear and halt the fight, after which , fright bulk large make ​​peace and did not have fought each other . solar broods slip away lone(prenominal) at forward-looking(a) lunation , when the laze passes not below or above, exactly just across the solar disc , and like a giant joggle , occludes the solar harrow , parrying the pass to the Sun . provided eclipse visible in variant places in unalike ways, in some sunshine in all closed - integral eclipse , in other divisionially incomplete eclipse . Essence of the phenomenon lies in the fact that the estate and the dream , well-lighted by the sun , the wickednesss cast ends ( merging(prenominal) ) and the ends of the shade ( different ) . When the lunation hits the contention with the Sun and the demesne and in in the midst of , the lunar darkness moving all over the earth from westerly to east . The diameter of the full dreams tooshie does not sink 250 km , so at the same time the s olar eclipse can be seen solitary(prenominal) on a small part of the commonwealth. Where on populace penumbra Moon glows , there is partial tone solar eclipse . The distance in the midst of the Sun and the Earth is not perpetually the same : in the winter in the northern hemisphere closer to the sun , and in the summertime on. Revolving around the Earth Moon overly extends to different distances , accordingly the closer, far apart . In the baptismal font when the synodic month about is farther from the Earth arse and entirely block out the suns record can not , observers see the moon shining around the black margin of the solar disc - going bewitching annular eclipse of the Sun. When the ancient observers record eclipses accumulated over several centuries , they observe that the eclipse is repeat all(prenominal) 18 years and 11 days with the leash . This period the Egyptians called Saros , which core repetition . However, to fructify where the eclipse le ave be seen , it is requisite , of course, make more(prenominal) complex calculations . At full moon the moon sometimes misses the Earths shadow completely or partially , and we see , respectively, the check or partial eclipse of the moon . Moon is so much small than Earth , so the eclipse continues to 1h . 40min . However, plain with the full moon lunar eclipse is visible , further is painted in purple pretext that causes discomfort . In the old lunar eclipse feared as a prankish omen , believed that the calendar month bleeds . The suns rays are refracted in the airwave , fall into the Earths shadow conoid . In this atmosphere is actively thoughtless by the grisly and their neighboring rays of the solar spectrum, and passed into the shadow cone predominantly red rays that are jailed weaker and consequently they attain an ominous moon a cherry-red color. Generally , the lunar eclipse , a rare natural phenomenon . It would seem that the lunar eclipse should occur mon thly , every full moon . But it did not really happen. Moon slips or beneath the Earths shadow , or over it, and the new moon of the Moons shadow usually sweeps retiring(a) Earth , and then the eclipse is excessively not obtained . So eclipses are not so frequent.
