How far are the stars from us?

After reading the book How Far Are the Stars from Us, I learned something, but I still don't understand a lot of knowledge in the book. I am very happy to be friends with this book. In the future, I will learn more about astronomy. Here are six short articles about how far the stars are from us for your reference!

How far are the stars from us?

Astronomy is a fascinating and fascinating subject. The author describes the process of creating "celestial ruler" by astronomers in past dynasties, and introduces the measurement and estimation of the distance from the moon to quasars near the apogee, which contains a lot of astronomical and historical knowledge. The work is fluent in writing and strong in story, which is a rare masterpiece of astronomical science.

How far are the stars from us? This book was written by Bian Yulin, a famous popular science expert. This is a book about astronomy. The "star" in How Far Are the Stars from Us does not simply refer to the stars we see, but to the constellations, the sun and the moon in the universe. The book says that there are millions of stars in the cluster of the Milky Way galaxy, and they form a team, just like the police are divided into several teams. Some stars are far away from us and some are close to us. The brighter the light of a star looks, the closer it is to us. The darker the light of a star looks, the farther away the star is from us, and the farthest galaxy is more than10 billion light years away.

This book is easy to understand. While introducing astronomical knowledge, we also attach great importance to the enlightenment of thinking. From ancient times to the present, stories of astronomical discoveries are interspersed from time to time, which not only show the course of scientific development, but also greatly stimulate readers' interest in reading.

This book is very well written and leads us to the door of mysterious astronomy. Astronomy is a mysterious subject that fascinates us. It studies tangible and intangible things, but it fascinates us with these tangible and intangible things. This book uses some modern things, which is in sharp contrast with previous daydreams. It shows the author's love for the sky and people's praise for the sky. Moreover, this book is beautiful in language and rich in content, so we can't put it down when we read it, and we can't bear to leave for a second.

If there is an opportunity, please read this book, explore this wonderful universe together, and walk into this wonderful astronomy together!

How far are the stars from us? Model essay ii of post-reading composition

Open the children's popular science book How Far Are the Stars from Us written by Bian Yulin, and you can read the beautiful poems of Guo Moruo, a great writer, which aroused my interest and attracted me to continue reading. The author talks about astronomical knowledge by literary means, such as the concepts of light years, parsec, constellations, bright stars and the Milky Way, and interesting knowledge about how to measure the distance between the moons and how to fly out of the solar system. The stories of astronomical celebrities in the book are particularly attractive. For example, Galileo, who invented the telescope, Heliocentrism and the geocentric struggle are all excited. Bruno was burned alive by the Vatican and Galileo was under house arrest. But people's temporary misunderstanding can never stop the truth. A generation of scientists paid a heavy price, including their lives, for upholding the truth.

Bruno insisted on the truth. In my opinion, people are inherently mortal, either lighter than a feather or heavier than Mount Tai. To die for the truth is the star in the sky, and people look up to it. Whenever I look at the twinkling stars at night, my tears are wet.

When I saw the chapter "The Real Discovery of the Milky Way", I knew that the German astronomer William Herschel in Britain was great! He made a reflective telescope with a diameter of1.22m and a length of12m, and discovered Uranus, Saturn and Uranus. 1783, he skillfully discovered that the sun has its own movement, and demonstrated that the sun moves in the direction of Hercules at a speed of 17.5 kilometers per second. He took Copernicus's Heliocentrism a big step forward. People will naturally come to the conclusion that the sun is not the center of the universe. Perhaps, the whole universe has no center at all!

Of course, there are some things in the book that I can't understand at present, such as geodesy, Kepler and his three laws. They used a lot of mathematical formulas, calculation methods and astrophysics knowledge. But it also made me understand that if you want to be an astronomer, you need a solid mathematical foundation and agile and rigorous thinking! In addition, it is important to be interested in astronomy. More importantly, we should have perseverance and try to observe the astronomical phenomena for years. It takes a lifetime of hard work to become an astronomer.

The universe! How far are you!

How far are the stars from us? Reading model essay III after reading.

At night, the stars twinkle overhead. Whenever I look up at the starry sky, there is always a question-how far are the stars from us?

How far are the stars from us describes how to measure the distance of some astronomical targets with trigonometry, Kepler's law, transit of venus, stars and aberration, and many interesting stories and pictures are inserted in the book. Make this book look lively and interesting, and let readers wander in the galaxy.

How far are the stars from us? It is like a "celestial ruler", measuring the distance from every variable star, galaxy and galaxy to us, so that we can truly appreciate the vastness of the universe. It has also brought our curiosity about space closer.

Various physical models, the "period-luminosity relationship" of variable stars, the "red shift" law of galaxies and so on. Let us see the diligence and efforts of astronomers, and even insist on the truth from generation to generation, which has laid a milestone for us to explore the starry sky.

From variable stars to supernovae, from democritus to Kant, vivid historical stories and the discovery of planets are the painstaking efforts of thousands of astronomers in Qian Qian. They not only let us see the complete galaxy, let us know more about astronomy, but also give us the motivation to explore galaxies.

How far are the stars from us? We are introduced to the dimming period of some variable stars, the concepts of magnitude and absolute magnitude, the relationship between star spectrum and magnitude, the feasibility and limitation of spectral trial and error method, globular clusters ... which make you marvel at the ingenious methods of scientists.

The stars are far away from us. We can see and touch them, but we won't stop exploring.

Cover the aftertaste, through the ages, people look up at the sky, starry, concerned about Tianhe, dark, charming autumn night. How many people revel in this picturesque scenery.

How far are the stars from us?

At night, the stars twinkle in the sky ... How far are the stars from us?

I found the answer in how far the stars are from us. ...

The book says that there are millions of stars in the cluster of the Milky Way galaxy, and they form a team, just like the police are divided into several teams. Some stars are far away from us and some are close to us. The brighter the star's light looks, the closer it is to us, the darker the star's light looks and the farther it is from us. The farthest galaxy is more than10 billion light years away. The moon, the first stop for human beings to fly out of the earth and step into space, is the only planet where human beings have left footprints outside the earth so far. The moon seems to be an immortal "sky lamp".

Explain how far the stars are from us by various scientific methods, and analyze the distances of various planets from us. And the numbers in this book are also very rigorous. Let me understand that science needs rigor. Starting from "How far is the sun from us", this chapter fully tells us that our theory is based on step-by-step practice. From Where is the Bright Moon, I found that technology is advancing step by step. It takes less and less time to triangulate our distance from the moon to the radar and then to the laser, and the error is getting smaller and smaller, until now it is 2 to 3 centimeters. This successfully shows that science can really change the world and solve more mysteries.

Astronomy is a mysterious and fascinating subject. What it wants to study is tangible and intangible, but it fascinates us with these tangible and intangible things ...

How far are the stars from us?

Writing has always been my favorite thing, but I have never really published it. It never occurred to me to turn my delicate words into type. And this unexpected thing happened suddenly.

Last year1the end of October1the beginning of October, Teacher Wang Jian came to me and told me that it was rare to have the opportunity to write a reading guide on How Far Are the Stars from Us. Of course, I was filled with joy and nodded immediately without thinking. When I bought this book and read its introduction in the textbook, I began to retreat: This is a book about astronomy, can I understand it? How to write a guide? Without writing, I don't know how to write, let alone understand. How can I write a guide? ..... In the inner struggle, I crustily skin of head and began to read. At first, it was slow and painful, because the knowledge involved in astronomy, physics, mathematics and so on was very professional and I had never touched it myself. It took a month to read a book. Although I have a general understanding of the contents of this book, I still feel that there are many professional knowledge in the fog. However, I still have to write a reading guide, so I started reading for the second time. This kind of reading not only speeds up the reading, but also quickly sorts out the contents of each chapter and section, especially after reading the whole book, looking back at the contents of each chapter, I feel that I have a general impression in my mind and I am proficient in reading ideas and methods. However, I still have no idea about how to write an introduction. But it's time for the question again. I also made some suggestions on the topic of Teacher Wang. After Mr. Wang's comments, I found out how "dull" I was, and I didn't want to do it myself, let alone be a student! Teacher Wang showed me personally, and I realized that the original question could be so clever and interesting, which could really guide students to read famous books. So I started reading again, read it carefully, looked up information online if I didn't understand it, and took notes where I felt it. I really saw it this time, only to find that astronomy is very profound. Although this book is only a small part of it, it is very interesting, lamenting the magic and remoteness of space, and it is also very rewarding and has learned a lot of astronomical knowledge. Of course, I also wrote a few words myself, imitating Mr. Wang's question, which felt good. With the deepening of reading and the proficiency of writing skills, I am doing it confidently. It was at this time that I realized a problem: the original astronomical things were so wonderful that I liked them very much; It turns out that popular science works are not as boring and difficult as I thought, and I like them very much. So, if you don't try many things yourself, how can you know whether you like them or not? In this way, I had the idea of starting to read some popular science works. In addition, reading and life are the same. In life, I can also try something I have never done before, isn't it nice to add a touch of bright color to the plain and smooth life? No matter what color!

It is not easy to write a reading guide for famous books. Experienced a series of work such as repeated reading, consulting materials and thinking. Basically, except for class, I sit in front of the computer every day, and sometimes I can only do one question and answer for half a day. However, it is in this process of constant exploration and repeated revision that I feel that my work is very busy and full, and I live a practical life every day. Finally, the specified task was completed within the specified time, but it was not over. The birth of a work needs a period of "labor pains". Some time ago, editor-in-chief Li Yongmao asked me to modify it! However, when I look at the pages of decent words on the computer screen, my inner sense of fulfillment and accomplishment arises spontaneously.

Although the book has not been printed yet, although it is only a teaching aid, I feel the feeling of being an author. I hope there will be such an opportunity in the future, because this job not only brings me knowledge, trains my ability to write questions, but also stimulates my interest in reading popular science.
