Total lunar eclipse is a kind of lunar eclipse. When the moon, the earth and the sun are completely in a straight line, the moon itself does not shine, and the moon reflects the light of the sun. When the whole moon completely enters the umbra of the earth, the earth blocks the sunlight, and the moon will no longer reflect the sunlight, resulting in a total lunar eclipse. During the eclipse, the direction difference between the earth's sun and the moon is 180. Because the orbits of the sun and the moon in the sky (called ecliptic and ecliptic respectively) are not on the same plane, their intersection angle is about 5, so only when the sun and the moon are located near the intersection of ecliptic and ecliptic respectively, they can form a straight line and produce an eclipse. When the earth is sandwiched between the moon and the sun, a total lunar eclipse will occur. The moon itself does not shine, but reflects the light from the sun. The news reported that the best total lunar eclipse in China 10 was staged in 201year and1February. By then, as long as the weather is fine, almost all areas in China can enjoy the charming sight of a "red moon" hanging high in the night sky. It's a long way to go, Xiu Yuan. At this time, it is a total lunar eclipse. Meeting you has been my dream for many years, and it will come true tonight. Although it was very cold in winter, I decided to go out and watch the total lunar eclipse. The process of an eclipse can be divided into five stages: first loss, eating, eating, giving birth to light and last contact. First loss: The moon has just touched the umbra of the earth, marking the beginning of the eclipse. An example of a total lunar eclipse

Eclipse: The western edge of the moon is inscribed with the western edge of the Earth's umbra, and the moon just enters the Earth's umbra. Eclipse: The center of the moon is closest to the center of the Earth's umbra. Luminescence: the eastern edge of the moon is inscribed with the eastern edge of the umbra of the earth, and the total solar eclipse phase ends at this time. Final contact: the western edge of the moon is tangent to the eastern edge of the umbra of the earth. At this time, the whole eclipse was over. The extent to which the moon is eaten is called a "total eclipse".

It is equal to the ratio of the farthest distance from the edge of the moon wheel to the umbra of the earth and the meridian of the moon during the eclipse.

The stars have long been hidden, and the protagonist tonight is the moon. Slowly, 19: 33, I saw a hole in the moon, and this gap was slowly expanding when people could not just understand the Central Plains. The magical drama of the total lunar eclipse has quietly ended.

The shadow is getting bigger and bigger. By moonlight, I found that it was the projection of our earth that obscured the brilliance of the moon. The round moon has gone from missing a hole to covering less than half, from more than half a circle to a semicircle. Now the circle is still shrinking, the shadow is constantly expanding, and the earth will "meet" with the moon. This pair of "friends", this pair of "brothers" and this pair of "mother and daughter" are "snuggling" together, but their rare "encounter" has attracted the obsession of many hot-blooded teenagers. How I want to fly to distant space and hug you two to form an unprecedented magical and gorgeous picture of the total lunar eclipse. Oh, total lunar eclipse, how excited I am at this time.

The shadow has covered most of the moon, and the light of the moon is constantly gathering, and the night is more dense. You see, the great power of the universe, like a bright moon, has turned into a crescent moon, hanging in the sky, like a moon boat, carrying me and my friends to the vast universe and looking forward to the future dreams of mankind. The pointer of history will never stop, and human exploration will never stop. Humans want to immigrate to Mars and the moon, transform Venus and Mercury, conquer the entire solar system, and March into the depths of the universe ... When they suddenly look up, they find this crescent moon elegant and exquisite, much like a moving arch eyebrows and a smiling mouth, telling the beauty of the sky. Oh, total lunar eclipse, I love you, and I am more obsessed with the greatness and wonder of the universe.

The new moon is getting smaller and smaller, and the big moon has become a "lens". The "lens" is shrinking and the shadow is approaching step by step. Finally, there was only a glimmer of light left, and it was getting darker and darker. The once-in-a-lifetime total lunar eclipse finally belongs to us. The shadow erased the last ray of light of the moon, and the sky was dark everywhere, except around the moon, which still retained a little luster. The shadow and the moon are integrated. Oh, it is this mysterious veil that makes the vast universe leap with the brilliance of science. Total lunar eclipse, so mysterious, so charming. Tonight, we are together, you are above and I am below. Our strong curiosity and yearning for each other make us soul mates.

Oh, total lunar eclipse, I sincerely greet you.
