How is the diary about visiting the science and technology museum written?

Today, I had an astronomy class at the Science and Technology Museum. I am very interested in astronomy because it contains many unexpected things.

After the teacher's careful explanation, I understand that astronomy is very important to each of us, because it is related to the future life and death of our human beings, animals and plants. The teacher also introduced us to the Big Dipper and the North Star, which are all knowledge that we can't learn in Chinese math class.

What interests me most is the twelve constellations, each of which has its own legend. What shocked me most was the design of each constellation. Looking at these designs, we can associate them with the rich imagination of ancient people. This article comes from data management download.

Later, the teacher led us to know more about the sun, and let me know that the sun was born 5 billion years ago. It is scientifically speculated that the sun will disappear after 5 billion years, when our beautiful earth will be swallowed up. In other words, we humans can live on the earth for 5 billion years, which is not what I hope, because I believe that with our human intelligence, it can be overcome. If we can't overcome it, we hope that mankind will find another earth in 5 billion years.

Let's never face the disaster, and there will never be the threat of earthquake and tsunami.

Today, I gained a lot in the Science and Technology Museum. I also realized that it is not easy for scientists, and some even risked their lives to explore in the vast universe and find our future home. So I will cherish today's time to study hard, make contributions to mankind in the future, and let future people live a better life.
