Dear viewers, a total solar eclipse will occur nine twenty six AM tomorrow, wednesday, the twenty second of july. Today was an amazing day. There was a total solar eclipse in wun. I woke up early because I couldn't wait to see IT. My friends and I went down to the yancy river to find a good place to watch IT. We took cameras, chairs, food and drink and special glasses so we could look at IT. Lots of people gathered there to watch too. Slowly, the moon moved in front of the sun. IT looked like someone bit a hole in the sun. IT got darker and darker as the moon slowly covered the sun. At nine twenty six A. M, the moon completely covered the sun. The sky went dark. The crowd gasped and cheered. The light of the sun made a ring of light around the moon. I took this photograph. Then the total eclipse lasted for over five minutes. Then IT passed, and the sky started to get brighter again. I was really inspired by the eclipse this morning. In the afternoon, I spent hours reading about astronomer's eclipses and how the planets move in our solar system. The universe is simply amazing. I also watch some videos with famous chinese astronauts. I wanna become an astronaut or astronomer someday, too. The sky is the limit.

Seeing the wall go through the mountains like a dragon was really amazing. Many tourists from around the world were there, admiring this ancient marvel. Climbing the steps, I felt proud of our Chinese culture. It was amazing to think how people built it thousands of years ago. I felt excited and a bit tired, but the sense of accomplishment was huge. This visit taught me about the history and wisdom of our ancestors. It inspired me to learn more about Chinese heritage. The Great Wall is a symbol of our nation’s strength and resilience, and I will never forget it.

The sky is the limit. 日冕是指太阳大气层中最外层的一层，是太阳圆盘周围呈现出的一层耀眼的白色或粉色光晕。它在太阳表面下面约2万公里的地方开始形成，直到延伸到数百万公里的太空中。虽然他在太阳上看起来很模糊，但在太阳时和日全食时可以清晰的观察到，日冕是太阳大气中最外层的部分，温度非常高，通常在1到200万度之间，远高于太阳表面温度的5800度。这是因为日冕受到太阳磁场的强烈影响，而太阳的磁场经常发生变化。这种变化导致磁场线发生扭曲，释放出大量能量，加热了日冕。日冕不仅温度高，还充满了太阳风。这是由于日冕的气体从太阳表面向外喷射而成的。这些气体包含电子、质子和其他离子，它们可以在太阳风中传播到太阳系的其他行星和卫星。太阳风对地球的磁层和电离层产生很大的影响，这对通信和导航等技术都有很大的影响。日冕也是太阳耀斑的重要来源之一，当太阳的磁场发生剧烈变化时会释放出大量的能量，形成耀斑。影响到太阳系中的其他行星和卫星。总之日冕是太阳大气中最外层的一，温度非常高，充满了太阳风和能量，对太阳系中的其他行星和卫星都有很大的影响。它是太阳的一个重要组成部分，也是太阳活动和耀斑等现象的重要来源之一。 A solar eclipse happens when the moon comes between the earth and the sun. Because the moon is in front of the sun, IT hides a part or all of the sun. Even though the sun is four hundred times wider than the moon, it's also four hundred times farther away. Because of that, the sun and moon look like they are the same size to us. In a total solar eclipse, the moon completely covers the sun. If you're in the right place, you won't see the sun at all. Although an eclipse can last a few hours, totality usually doesn't last more than three minutes. We interrupt this video for an important safety announcement. Looking directly at the sun can hurt your eyes. This is true even during an eclipse. Luckily, there are a few ways to watch in a clip safely. The easiest way is to wear special eclipse watching glasses. These glasses are much, much darker than your usual sunglasses. Another way to watch the eclipse is to use a pinhole viewer first, make a hole in a piece of cardboard, hold the cardboard up to the sun, let the sunlight shine through the hole, and land on a second piece of cardboard. You can see the sun there. Once the moon completely covers the sun, IT will be too dark to see anything through the eclipse glasses. This stage of a total solar eclipse is called totality. It's safe to look at the sun during totality, but remember, if you're using eclipse glasses rather than a pinhole viewer, put your glasses back on before any sunlight appears. Again, any sunlight reaching your eyes, even for a few seconds, can hurt your eyes badly. During a total solar eclipse, animals and plants sometimes behave differently. Birds may stop singing, crickets may stop carping, and flowers may start to close up. Every year or two, a total solar eclipse takes place somewhere on earth, but it's rare to see one from the same place. Do you know when your country last experiences the total solar eclipse? 中国的那些英雄宇航员们，你还记得他们吗？本期视频带您特别盘点2003至2024历届英雄航天员，特此致敬中国英雄，致敬中国航天。一、中国首飞太空第一人，神舟五号航天英雄杨利伟。2、中国太空漫步第一人，神舟七号、神舟13号航天英雄翟志刚。3、神舟六号、神舟15号英雄航天员费俊龙。4、神舟六号、神舟十号、神舟12号英雄航天员聂海胜。5、神舟七号、神舟12号英雄航天员刘伯明。6、神舟七号、神舟九号、神舟11号、神舟16号英雄航天员景海鹏。7、神舟九号英雄航天员刘旺。8、神舟九号、神舟14号英雄航天员刘洋。九神舟十号英雄航天员张晓光。十神舟十号、神舟13号英雄航天员王亚平。十一神舟11号、神舟14号英雄航天员陈东。十二神神舟12号、神舟17号英雄航天员汤洪波。十三神舟13号、神舟十8号英雄航天员叶光富。十四神舟十4号英雄航天员蔡旭哲。十五神舟15号英雄航天员邓清明十六神舟15号英雄航天员张璐十七神舟16号英雄航天员朱杨柱十八神舟16号英雄航天员桂海潮、十九神舟17号航天员唐胜杰二十神舟17号航天员江新林二十一神舟18号航天员李聪二十二神舟18号航天员李广苏作为一名航天爱好者，收藏多年新签的航天首封，有感兴趣的朋友小红书。 地球绕太阳运行，而月亮绕地球运行。当月亮在绕地球运行的过程中移动到太阳和地球之间时，它会遮挡阳光，从而在地球的部分地区投下阴影，这称为日食或太阳时。换句话说，当月亮在太阳和地球之间成直线通过时，就会发生日食，民间称此现象为天狗食日。日食有四个类型，第一种也是最壮观的类型是日全食。日全食发生在月球完全遮挡太阳时，只有当你站在本影阴影内时才能看到日全食。该路径称为全时代随着月球移动而在地球表面掠过，处于半影阴影中的人们只能看到部分日食。第二种是日环食。日环食发生在月球直接经过太阳前面时，但月球看起来太小而无法完全遮挡太阳。这是因为月球的轨道是椭圆形的，有时它离地球更近，有时更远。第三种类型是日偏食。当月亮只遮挡一部分太阳，并在地球上投下半影时，就会观测到这种类型的日食。由于它只遮挡太阳的一部分，因此这种现象称为偏食。最后一种是混合日食，这是所有日食中最罕见的当月亮在太阳和地球之间的位置如此微妙的平衡时，地球的曲率会发挥作用，我们称之为混合时。在该类型的日食期间，地球的部分地区会看到环食，而其他部分则会看到全食，因此这种类型的日食也被称为混合全食。日全食看似更罕见，因为全食阶段仅持续数分钟。此外，尽管地球平均每18个月发生一次日全食，但每次全食只能在地球表面不到0.5%的范围内可见。
