Help write an essay on total solar eclipse observation, about 800 1000 words

At 9:35 a.m. on July 22, a total solar eclipse will be staged over the densely populated Yangtze River basin in China. This will be the longest visible total solar eclipse in China since 1814, with the largest number of observable people and the most spectacular scenery.

At 8:30 a.m. 10:30 a.m., we will observe the most spectacular total solar eclipse once in 500 years in Quzhou, and gradually the time comes to the total solar eclipse, I immediately took out my sunglasses and faced the sun, only to see a round of fiery red sun in the black back, and then like a tengu eating the moon, there are cracks on the sun that are bitten by teeth, 1 minute has passed, I am watching the sun disappear little by little, when the moon blocks the sun all, the sky is dark and I can't find any traces of the sun. Gradually, I saw a star-like thing and a black sun, only to see that the sun was like eating a fairy's Yaochi fairy dew and began to slowly recircle again, the sky was bright again, and the stars were gone, the world is really wonderful!

But I don't know why a solar eclipse happens, and I only blame me for not learning enough, so my father, a jack of all trades, immediately told me about .........It turns out that a solar eclipse is a solar eclipse after the moon blocks the sun, and the sun does not shine on the earth, so it forms a solar eclipse. We saw it all five times, but there were a lot of clouds, and the sun was in the clouds a lot of the time.

Principle of Solar Eclipse A total solar eclipse occurs because the Sun is close to a point where the Moon's orbit meets that of the Earth, and at the same time the Moon is at the closest point to that point. An annular solar eclipse occurs because the Sun is close to an intersection of the Moon's orbit and the Earth's orbit, and the Moon is at the farthest point from that point. Since the beginning of the food loss, it is the partial food stage.

As the moon continues to move eastward, the part of the sun's circle that is obscured by the moon gradually increases, and the intensity and heat of sunlight decrease significantly. When the eastern edge of the lunar surface is intangent to the eastern edge of the solar surface, it is called an eclipse. At this time, the entire circle of the sun is obscured, so the eclipse is the moment when the total solar eclipse begins.

The reason why a total solar eclipse occurs is because there is a magical symmetry. The Sun is 400 times the diameter of the Moon, and it is exactly 400 times the distance from the Earth. As a result, when the Moon is completely between the Earth and the Sun, the Sun's surface is completely obscured for those who are completely in the Moon's shadow.

The sun turned black, leaving only a golden halo, and the sky turned indigo. Birds may lose their orientation or fly back to their nests, while bats and other nocturnal animals may come out sleepy.

It's really a world full of wonders!

What sun has changed? How can it be? Indeed, on the morning of July 22, 2009, the sun really changed.

In the early morning, the sun shines brightly as usual. Suddenly, at 8:23, the sun seemed to be missing a small piece, and I was very surprised, and my mother told me that it was a total solar eclipse, that is, the phenomenon of the moon occupying the sun, which is what the old people call the tengu eclipse sun, oh! It turned out that the sun had just been bitten by a "tengu".

Slowly, the sun in the sky became smaller and smaller, and when the sun was about to be swallowed by the "tengu" completely, it seemed that the sun had turned into a big and bright diamond ring hanging high in the sky, and I really wanted to take it off and give it to my mother! The diamond ring is gone, and the sun has become a shining "Bailey Pearl" When I was still immersed in this beautiful transformation, the sun seemed to be swallowed up by the "tengu", and the day instantly turned into darkness, and I felt scared: if the sun is really eaten by the "tengu", if the sun never comes out, what should I do with every grass and tree on the earth, what should human beings do, and I should live in **?

Just when I was infinitely worried, the lovely sun showed a glimmer of light, and then his little head was also revealed, and I exclaimed excitedly: "The sun has changed, the sun has changed!" ”

I love the change, it's magical, it's beautiful, and it makes me look forward to its next time.

One summer vacation last year, at about 4:00 a.m., everyone came to the beach early, it was still dark, and the stars winked at me mischievously. We wore sunglasses and waited for the eclipse to arrive.

The person next to us enthusiastically explained: "This is because the earth revolves around the sun and the moon revolves around the earth, so there is a natural phenomenon such as a solar eclipse." Suddenly, I heard a child shouting

Look, everyone! The eclipse is coming! "We raised our heads to look at the sky, and there was really a golden, dim light floating on the surface of the sea, and after a while, the light became brighter, like a huge scythe across the sea.

At 4:25, the sun gradually became semicircular, and the sun father was finally willing to show "half of his face". The colorful light makes people who don't wear sunglasses feel uncomfortable.

At 5:00, the sun showed more than half of it, like a wooden boat, and the dazzling light made people unable to open their eyes. The sun rose, but as if it had been bitten off by something, a horn was missing, and gradually, a dark shadow visibly obscured it.

We found that the black shadow was getting bigger and bigger, and the sun was getting smaller and smaller, becoming a "crescent moon," and before long, the black shadow covered the entire sun, leaving only an intermittent halo in the sky, but after a while, the halo slowly connected itself, like the King Kong circle of Taishang Laojun. I looked at my watch, and it was exactly 10:05, the same time as the trailer.

The solar eclipse is so beautiful, today is finally not in vain! ”

I don't know, think for yourself, I can't help it.

One day during my summer vacation last year, I saw a once-in-a-century astronomical spectacle – a total solar eclipse.

The total solar eclipse occurred on the morning of July 22, 2009, and a few days before the total solar eclipse, my dad told me something about astronomy. Observing a total solar eclipse requires a type of glasses – solar goggles – because these glasses protect our glasses. 8：

At about 22 minutes, the eclipse began, and I watched for a while with my sunscope on my goggles, and suddenly a small gap appeared in the sun. At this time, the sun is like a child taking a small bite of a mooncake. About half an hour or so I put on my goggles and looked at the sun again, and the sun was already half missing, and after a while, the sun was completely obscured by the moon, and the sky was like dawn.

When the sun showed a little, it was so dazzling, like a diamond ring shining its beautiful light, and after about half an hour, the sun gradually returned to its original appearance, and its sun was still so bright, still shining on the earth.

After this total solar eclipse, I learned a lot about astronomy.

The miraculous total solar eclipse quietly lifted her veil with cheers from all corners, she is so beautiful, and her appearance has written a new chapter in the land of China for 5,000 years!

I learned about the process of a total solar eclipse from the book, that is, the process of a total solar eclipse can include the following five periods: the first loss, the eclipse, the eclipse, the light, and the round.

I feel very fortunate to be able to see this once-in-a-century fantastic total solar eclipse, but perhaps because the weather is not beautiful, this morning's weather is like a masked girl, surrounded by clouds. I kept praying, hoping that the clouds could disperse and the long-awaited sun appeared, I silently counted the time, and suddenly the sky was clear, maybe the sun was moved by me, look at what it was, ah, it was a total solar eclipse, he came like a beautiful fairy, it was more than 9 o'clock, the sun's light was gradually blocked by the moon, like a big red apple was slowly bitten off. There is a sense of mystery about me, who has never seen a total solar eclipse. When the sun was about to be completely blocked by the moon, the sky turned dark, and I felt that it was a beautiful and spectacular watercolor painting that nature had given us humans.

And at the eastern edge of the sun, an arc of diamond-like light will suddenly appear, like the eye-catching sparkle on a diamond ring, which is the diamond ring, and at the same time, it will instantly form a string of glowing bright spots, like a string of brilliant pearls hanging high in the dark sky, this phenomenon is called pearl eclipse. Slowly, the sun returned to its original state.

Although the total solar eclipse is only once for us, but for the whole China, and even the whole world, it is a rare wonderful spectacle, I believe, the spectacle of the total solar eclipse once again proves that the universe is so big, there are no wonders, maybe the total solar eclipse is just a small beginning, and more unexpected wonderful landscapes will appear again in the universe!
