The observatory's daily diary is 300 words

Last Saturday, my good friend and I visited the Yunnan Observatory in Fenghuang Mountain, the eastern suburb of Kunming. As soon as we arrived at the Observatory, the narrator's uncle and aunt took us to the Science Museum to see the introduction of space knowledge. What about Mercury, Venus and Jupiter? Every object attracts us deeply and fascinates us. There is also a popular science exhibition on Chinese lunar exploration and space science in the popular science museum.

After reading the introduction of space knowledge, we used an astronomical telescope to see the sun. The children and I lined up one by one and took turns watching. It's my turn I am so excited. I slowly put my eyes close to the telescope and watched it carefully. I saw some sights that are usually invisible to the naked eye, such as sunspots, flares and corona around the sun.

After watching the sun, my uncle and aunt took us to visit the sundial. A sundial, also known as a sundial, is a device that uses the shadow cast by the sun to determine time. A sundial consists of a copper pointer and a stone disk. The copper pointer is called "dial pointer" and passes through the center of the disk vertically. The stone plate is called "noodles" and has scales on it. The moving shadow of the hand seems to be the pointer of a modern clock, while the surface of the hand is the surface of the clock to show the time. The sundial timing method is a great invention of human beings in the field of astronomical timing.

After watching the sundial, we went to the planetarium to watch the starry night video of the four seasons. The Big Dipper is the most striking star in the spring night sky. Its handle points to the east and protrudes from the handle of the Big Dipper. We see arcturus, the shepherd's bright star. Scorpio is the most striking constellation in the summer night sky. Located in the center of the blue sky, it is a remarkable symbol of the summer night sky. Cassiopeia is the most recognizable in the autumn night sky. It is the most striking constellation in the autumn night sky. Orion is the most striking constellation in the winter sky, along with Orion and companion clouds.

On the way back from the Observatory, I was excited for a long time, because I learned a lot of astronomical knowledge, which aroused my strong interest in space science and technology. In the future, I will work harder, learn scientific and cultural knowledge well, and strive to make my own contribution to our great motherland.
