Content abstract: how far is the star from us? Why does the sun shine? What's the matter with comets and meteors? Is the universe really expanding? Are there any aliens? The book "talking about the universe" contains 10 topics, covering a series of basic astronomical problems, such as the moon, the sun, eclipses and eclipses of the sun, the solar system, the starry sky, stars, the Milky way and extragalactic systems, the evolution of the universe, aliens and astronomical telescopes. This book deduces the original professional topics in a very popular language. Every reader of culture above junior high school can understand them with his or her heart. He or she is a good teacher and friend for every astronomy loving reader.
Talking about the universe
Qu Yuan, a scholar and poet of Chu state in the Warring States period, wrote the immortal chapter "asking for the sky", which represented the endless questions and exclamations that the ancestors had sent out in the face of the blue and deep starry sky. Astronomy is one of the oldest disciplines. In the 21st century, the research of astronomy and cosmology has made rapid progress and achieved fruitful results. These research results are the precious wealth of human knowledge. On the other hand, with the development of society and the improvement of public cultural quality, more and more people are interested in astronomy, which requires a bridge between modern astronomy knowledge and the public. Mr. Lin Yuanzhang's "talking about the universe" is a rare excellent work of astronomy popularization, which is also such a "Hongqiao".
Chang'e, China's lunar exploration project, has made remarkable achievements. If you want to know what the objectives of the lunar exploration project are, what it means to mankind, and the most basic knowledge and data about the moon, you can find the most detailed answers in this book.
The sun is the most closely related star body to the earth and human existence. Where does the energy of the sun come from? Is the solar energy mechanism really related to the hydrogen bomb, which is a powerful weapon? How many years can the sun burn? How will sunspots, flares and other activities on the sun affect our earth's environment? To these interesting questions, the book is in popular language for the readers.
Although the natural environment on the surface of Mars is very different from that of the earth, it is still the most similar object in the solar system. Although there are many reports that water ice has been confirmed on Mars, whether there is liquid water on the surface of Mars is still an open question. Whether there is even the lowest life on Mars is a bigger question. Now many countries, including China, are making ambitious Mars exploration plans, believing that there will be a great breakthrough in human Mars exploration in the near future. In this book, we have a very detailed introduction to the understanding of Mars.
Ancient Chinese astronomers left the most abundant records of astronomical observation, in which "guest stars" were frequently mentioned. How to explain "guest star" in modern astronomy? How did the "Tianguan guest star" observed in the Northern Song Dynasty relate to the famous "crab nebula" in the sky? If they are related, what is the basis? Supernovae are not "new" at all. They are a "Phoenix Nirvana" explosion when a star evolves into old age. What is the process?
Now when we hear the saying "Big Bang", I believe many people will not feel very strange. But how long has it been since scientists came to the conclusion that the universe was born in a big bang? In other words, what is the basis of the big bang? Many people may not be able to explain these problems clearly. The book "talking about the universe" introduces the work of famous cosmologist Hubble and others in detail, including the early research on Cepheid variable stars, the confirmation of extragalactic systems, the redshift of spectral lines, the problem of cosmic microwave background radiation, and explains the relationship between "cosmic expansion" and "Big Bang".
"Dark matter" and "dark energy" have become very fashionable scientific words. The problem of "dark matter" comes from the observation of the motion state of stars in galaxies, and the inference of "whether Newton's law of motion is universally applicable on the scale of the universe"; the problem of "dark energy" comes from the observation of the acceleration of thousands of galaxies away from the river. What is "dark matter"? What is "dark energy"? Why is there such a saying? What's the difference between them and ordinary matter and energy? How do scientists study them? This series of questions can be found in this book.
The universe is vast and magnificent. After reading "talking about the universe", readers will surely feel that there is more to be thought about, such as increasing knowledge, expanding horizons.
