The earth to the moon and the sun in the middle of the sun's light blocked by the Earth just can not reach all parts of the moon up, so there shadows on the moon, a phenomenon called "Eclipse." Sunlight blocked by the Earth all the time, called "total eclipse"; partially blocked, the called "eclipse"

Acquaintance eclipse
In ancient times, people do not know the scientific reason eclipse, solar eclipse, like fear, like fear of the eclipse can also harbor. Some foreign legend, the early 16th century, Columbus sailing to South America, Jamaica, and the local indigenous people conflict. Columbus and his sailors trapped in a corner, out of food without water, the situation is very critical. Know something about astronomy, Columbus knew the total lunar eclipse that night to happen to the indigenous people shouted, "do not take food to, do not give you the moon!" In the evening, Columbus, then to pass, and sure enough there is no moonlight. Upon seeing the fear and trepidation of indigenous people, quickly and Columbus turn hostility into friendship.

Eclipse is a special astronomical phenomena, that When the Moon to the Earth's shadow part, in the area between the Moon and the Earth because the Earth by the sun cover is closed, to see the missing piece of the moon. That is, at this time of the sun, Earth, Moon exactly (or almost) the same line, so the moon from the sun to light will be obscured by the Earth. The earth, when the eclipse occurs when the direction of the sun and the moon will be 180 degrees, so the eclipse will occur in the "look" (ie, after the Lunar New Year 15). Note that, due to the sun and the moon's orbit in the sky (known as the ecliptic and White Road) is not in the same plane, but about 5 degrees angle, so only the sun and the moon are yellow or white Road at two intersections near chance even in a straight line, resulting in eclipse.

Lunar eclipse can be divided into partial eclipse, total lunar eclipse and the penumbral eclipse of the three. When only a portion of the Moon into the Earth's umbra, the eclipse occurs; and when the Moon enters the Earth's umbra, the total lunar eclipse occurs. The penumbral eclipse, the moon is just passing the Earth's penumbra, resulting in very slight on the weakening of surface brightness, it is difficult to see the difference with the naked eye, it is not that people notice. Earth's diameter is about 4 times the moon in the lunar orbit at the Earth's umbra is still equivalent to the diameter of the moon 2.5 times. So when the center of the Earth and the Moon approximately in the same straight line, the moon will be completely into Earth's umbra, and have total lunar eclipse. And if the moon has covered only a portion of the Earth umbra, that is only part of the moon into Earth's umbra, a partial eclipse occurred. Does not appear on the moon on the Environment and Food. Because the size of the moon much smaller than the Earth. The diameter of the sun is much greater than the diameter of the Earth, the Earth's shadow can be divided into umbra and penumbra. If the Moon enters the penumbra region, the sun's light can also be concealed out of some astronomical phenomenon known as the penumbral eclipse. As the sun in the penumbra is still very strong, the brightness of the lunar surface is only a very slight decrease in most cases penumbral eclipse is not easy to distinguish with the naked eye. In general, the more difficult to find man, it is not known as the eclipse, the eclipse is only total lunar eclipse and a partial eclipse of two. In addition, as the Earth's umbra is much greater than the moon, which means the total lunar eclipse occurs when the moon completely into the Earth's umbra area, so it will not appear on a monthly loss of this phenomenon. Eclipses occur each year the number is 2 times, up to 3 times occur, and sometimes does not occur again. Because in normal circumstances, the moon is not from the top of the earth through the umbra, is at the bottom left, rarely through or partially through the Earth's umbra, so under normal circumstances would not have happened eclipse. According to observational data statistics, the per century penumbral eclipse, partial eclipse, total lunar eclipse occurred about 36.60% percentage, 34.46% and 28.94%.

Eclipse process
Moon leaves penumbra months after the beginning of total eclipse: lunar penumbra just and contacts, when the naked eye can not perceive. The formal beginning of the eclipse of the process is divided into losses, both fresh eclipse, raw light, complex circle of five stages. Early losses: Mark beginning of an eclipse. From the eastern edge of the moon slowly into the shadow, the moon and the Earth umbra, the first cut. Fresh both: West edge of the moon and the Earth within the umbra of the West edge of the cut, all entered the Earth's moon is just inside the umbra. Eclipse: The center of the umbra the Moon and the Earth's center recently. Health: East edge of the Moon and the Earth within the umbra relative to the East edge of the cut, then the end of totality. Umbra: West edge of the moon and the Earth umbra east edge of the phase cut, then the whole process of the end of the eclipse. Moon is the amount of feeding is called "eclipse", when it is equal to eclipse the umbra on the earth round the edge of in-depth as the maximum distance by the ratio of the Moon. Penumbral eclipse ends: Moon left the penumbra, the eclipse of the official end of the process.

Lunar eclipse has been promoting the development of human knowledge. Lunar fifteen, sixteen, run to the moon and sun relative to the direction. Then if the center of the Earth and the Moon approximately in the same line, the moon will enter Earth's umbra, and have total lunar eclipse. If only part of the moon into Earth's umbra, it creates a partial eclipse. When the Moon enters Earth's penumbra, they should be penumbra food, but because of its brightness decreased very little, difficult to detect, it is not known as the eclipse, the eclipse is only total lunar eclipse and a partial eclipse of two. Lunar eclipse took place in sight (full moon), but not every eclipse all hope, this and every new moon eclipse is not all there is the same reason. Eclipse eclipses and collectively. Principle by the eclipse can be seen, the emergence and eclipse day, the month meet the three movements is closely related to the rendezvous with the periodic motion, so naturally there should be periodic eclipses. Eclipse cycle is found in the ancient Babylonians, called "Saros cycle" ("Charo" is the meaning of repetition), for 18 years and 11 days more. Is 6585.32 days.

Earth in the direction away from the sun appears a shadow, called the shadow. Umbra and penumbra of the shadow is divided into two parts. Umbra is not subject to too much direct sunlight, but only by some direct sunlight penumbral light. Moon around the Earth is running sometimes into the shadow, which resulted in a lunar eclipse (see Figure I). When the moon entered the umbra are when the total lunar eclipse will occur; but if only a part into the umbra, then the partial lunar eclipse will occur. Umbra and the eclipse is total lunar eclipse lunar eclipse. In the total eclipse, the moon is not completely invisible, which is due to sunlight through the Earth's thin atmosphere by refraction into the umbra, projected onto the lunar surface, so to appear before January of red copper. Depending on the path of the moon through the umbra, and when the planet's atmospheric conditions, light intensity at different total eclipse will be different. Sometimes the moon will not enter the umbra into the penumbra only, which is called a penumbral eclipse. During the penumbral eclipse occurs, the moon will be slightly dimmer, but the limb will not be obscured by the Earth's shadow.
Ancient eclipse records of historical events is sometimes used to presumed age. Ancient Chinese superstition that the moon is also called Tengu eat.

Total lunar eclipse brightness rating
L = 0 dark (eclipse, the moon almost invisible) L = 1 black with gray or brown (difficult to distinguish detail) L = 2 dark red or rusty red (central dark umbra relatively bright, but peripheral) L = 3 brick red (with yellow light or the edge of the umbra) L = 4 bright orange-red (bright umbra, the edge with blue) Total lunar eclipse brightness rating 2 visible main crater on the sea and other details to be shaped with a small pair of binoculars (diameter 4 cm or less) before they can see 5cm to 15cm diameter 1 have only seen the details of the telescope 0 15cm or more telescopes have only seen the details of Both the data is very important in doing the official total lunar eclipse observing these two parameters need written report.
Eclipse of the principle. Lunar fifteen, sixteen, run to the moon and sun relative to the direction. Then if the center of the Earth and the Moon approximately in the same line, the moon will enter Earth's umbra, and have total lunar eclipse. If only some of the principles of the moon ball into the ground eclipse umbra, to produce a partial eclipse. When the Moon enters Earth's penumbra, they should be penumbra food, but because of its brightness decreased very little, difficult to detect, it is not known as the eclipse, the eclipse is only total lunar eclipse and a partial eclipse of two.

The earth, when the eclipse occurs when the direction of the sun and the moon will be 180 degrees, so the eclipse will occur in the "look" (ie, after the Lunar New Year 15). Note that, the eclipse can only occur at full moon, this time, the sun, Earth and moon form a straight line, the entire lunar surface is illuminated, so as long as the days of clear air Lang, guaranteed to see to see this spectacular scenes. However, not every full moon eclipse will occur because the Moon's orbit around the earth off the ecliptic of about 5 ° of the angle, only the moment when the full moon happens to be on the moon in its orbit through the ecliptic plane only when a total lunar eclipse.

Many people have seen a lunar eclipse, a partial eclipse and total lunar eclipse lunar eclipse two. Total eclipse phenomenon is very beautiful. Had a bright moon hanging in heaven slowly become blocked by a smaller shadow, and finally disappeared completely in the dark sky. Just when you do this lament, you will find that the moon had just disappeared Youyi see another ordinary copper red look in front of you, make you marvel. So if you know why a lunar eclipse and total lunar eclipse occurs when the moon did it come in red? Watch over the people know that a lunar eclipse, a lunar eclipse will occur in the full moon, the Lunar fifteen or sixteen. The reason is easy to understand, because only the full moon, the Earth was at the moon and the sun. However, and not every full moon lunar eclipse occurs when the phenomenon, which is why? It turned out that the moon's orbit around the earth around the sun and the Earth's orbit is not in the same plane, but there is an approximately 20 degree angle or so, so when the Earth is between the sun and the moon, this is often not in the same three a straight line, when the Earth's shadow will not fall on the moon. Only when all three happened to be in the same straight line only when a lunar eclipse. So, total eclipse because the moon turns red, what is it? It turned out that the Earth's atmosphere caused by the refraction of sunlight. Total lunar eclipse when the shot came from both sides of the Earth's atmospheric refraction of sunlight by the Earth into the Earth's shadow. Refraction of monochromatic light of various colors formed, only red light is easy to reach the lunar surface by the earth's atmosphere, the other colors of light have been blocked and absorbed.

yueshi Eclipse lunar eclipse Moon enters Earth's shadow darkens the moon's surface phenomenon. Earth in the direction away from the sun there is a shadow. Umbra and penumbra of the shadow is divided into two parts. Umbra has not been a direct shot to the sun light, part of the penumbra by the direct solar radiation to the light. Moon around the Earth is running sometimes into the shadow, this lunar eclipse (eclipse causes of Figure 1). Moon have entered the umbra, the total lunar eclipse occurs; only part of entering the umbra, a partial eclipse occurs. Umbra and the eclipse is total lunar eclipse lunar eclipse. Sometimes the moon does not enter the umbra into the penumbra only, this is called a penumbral eclipse (Figure 2 Three eclipse). Eclipse of the moon into the shadow of the phenomenon, so the eclipse can only occur in the "look" that occurred after the Lunar New Year on the 16th. As with the ecliptic and white, about 5 ° 9 □ inclination, so not every Full Moon eclipse occurs, and only the yellow and white when the moon to run near the intersection only when the eclipse can occur. If one consider the umbra eclipse can occur up to 3 times per year, at least you did not even once. The probability of occurrence of 2 times per year maximum for two-thirds. Such as the penumbral eclipse is also taken into account, may occur up to 5 times per year, occurred at least 2 times, but still in each of the umbral eclipse 2 times the maximum probability of about 60%; followed by a penumbral eclipse occurred in 4 or 3 or penumbral eclipse umbra and penumbral eclipse of the 1, the probability of each of these three is about 8%. According to 1500 BC ~ AD 2500 occurred among the 9,729 and the eclipse will occur in the statistics, the average per century penumbral eclipse occurs 89.0 times, 83.8 times eclipse, total eclipse of 70.4 times, a total of an average of 243.2 times per century . Eclipse in the face of the moon can see the eclipse half the globe, so a specific location for about half of the eclipse can be seen above. The size of the eclipse with the eclipse degree to represent. Is equal to eclipse eclipse, the moon eclipse, as the diameter of the part when the moon entered the umbra, as the diameter ratio. Lunar eclipse time as appropriate and cut inside the umbra, eclipse equal to 1. Eclipse umbra further time as the moon, eclipse, said with greater than 1. Total eclipse of the eclipse is greater than or equal to 1. Partial eclipse points are less than 1. Penumbral lunar eclipse with the eclipse into the penumbral part of the diameter of the moon expressed as the ratio of the diameter. Penumbral eclipse the eclipse is greater than 0.7, the human eye can perceive. As with the solar eclipse, lunar eclipse is also cyclical, the solar eclipse of Saros cycle also applies to eclipse. The so-called Saros cycle is 223 synodic months, that is 6,585.3 days, together 18 years and 11 days (this time a leap year if the five and 18 years and 10 days). For example, 17 July 1981 lunar eclipse, 18 years and 11 days later, on July 28, 1999 lunar eclipse also occurred. 223 the number of synodic months is not the day, there are a few more than 0.3 days, not just equal to the intersection of 19 years, and 0.5 days of poor, so, after a Saros cycle, the eclipse time about 7 to 8 hours later. The position of the moon relative to the intersection and not the same when the last eclipse, eclipse there will be changes. Yin Ruins in Anyang oracle bones unearthed in the eclipse to have been recorded about BC's thirteenth and fourteenth century. "Yizhoushu" recorded in a lunar eclipse, according to research BC January 29, 1137 eclipse. "Book of Songs Xiaoya" records a lunar eclipse, look at the Zhou You Wang in September six years, that in 776 BC on August 21. There are also many ancient historical eclipse records.
