Our reporter asked people what they were doing on July 20th, 1969 when man first walked on the moon. Here is what they said:

Kate Jones, waitress I remember that day very well. I was fifteen years old. It was a hot and humid day, and I was with my family in the mountains. We were having a picnic. We didn’t see the moon landing when it happened, but we were thinking about it. We saw it later on the TV news.

John Bates, postman I was eighteen years old. It was a very exciting day. I was watching TV at home when the astronaut walked on the moon. His name was Neil Armstrong. I remember he could jump really high because people aren’t so heavy on the moon. When he returned, he became a national hero in America, and famous all over the world.

Paul Robinson, doctor I was twelve. I remember the day, but I don’t remember what I was doing. I remember I wanted to go to the moon, too. My dream was to become an astronaut and fly in a rocket. I wanted to see the earth from the moon. The astronauts on the moon said that the earth looked very beautiful from there.

Linda Brown, clerk I was working that day. I was twenty then. I didn’t see the man land on the moon because I was busy. Of course I knew about it. I read about it in the newspaper the next day. I thought it was amazing. Maybe one day people will travel to the moon for vacations!

Mark Green, teacher I was only seven years old then. My parents talked about it, and I learned about it later in school, but I don’t remember the day. I was too young to remember. Maybe I was having fun in the playground with my friends when it happened.

China’s Shenzhou-13 crew members Zhai Zhigang, Wang Yaping and Ye Guangfu livestreamed the first science lecture from the country’s space station on Thursday, December 9th, 2021, which amazed many students on the earth.

All crew members greeted students, teachers and other participants when the lecture started. They showed viewers how they lived and worked inside the space station, which currently consists of a core module(核心舱), a spacecraft and two robotic cargo(货物) spaceships.

The astronauts displayed their exercise equipment and a specially designed space suit, and conducted demonstrations(演示) on physical phenomena(现象) in microgravity, such as “disappearing buoyancy(浮力)” and a “water ball”. Ye, who is on his first spaceflight, showed how he rotated his body in the weightless environment. The astronauts also answered questions from students during the lecture.

Tens of millions of primary and middle school students across China watched the televised event hosted by the China Manned Space Agency, the Ministry of Education and other government departments.

It was the first lecture of the Tiangong Class, China’s first extraterrestrial(外星的) lecture series to popularize space science.

More lectures will be held based on the country’s manned spaceflights and will also be presented by Chinese astronauts, the manned space agency said. Such activities are intended to spread knowledge about manned spaceflights and spark enthusiasm for science among young people.

Shi Yi, deputy head of teaching and a physics teacher at the Beijing No. 101 Middle School, said the space lecture was an eye-opening experience that would ignite students’ interest in science.

Wang Yihan, a fifth-grade student, said, “The astronauts’ experiments really interested and surprised me. I have great interest in spaceflight and would like to take part in our country’s space exploration program in the future.” Vincent Wong Wai-shing, deputy principal of Hong Kong’s Pui Kiu College, said after watching the lecture that the event gave Hong Kong students an opportunity to communicate with the astronauts while stimulating their interest in space and science. “It also helped to enhance(增强)their sense of national identity as they saw the rapid development of our country’s space technology,” he said.

“Twinkle Twinkle Little Star” is a popular song for children. But have you ever wondered why the stars twinkle? I’m afraid many adults don’t understand this question, let’s unlock the mystery of the stars!

When we look up to the sky on a clear, dark night, our eyes can see about 6,000 stars in the sky. Some stars look like they are always twinkling and winkling. They are very beautiful. In fact, most of the stars are shining with a steady (稳定的) light. Not all stars twinkle. The stars that twinkle are generally stars. In addition to the Sun, the nearest star to the Earth, the neighboring star (比邻星), is also more than 4 light years away from Earth. Because the distance is too far, the stars we see are only a small point. Also, from the distant star travels a long way through the atmosphere (大气) down to us on Earth. At the same time, air is moving in the atmosphere of Earth. The movement of air causes the starlight to get slightly bent. To our eyes, this makes the star to twinkle. You will notice that stars closer to the horizon appear to twinkle more than other stars. This is because there is more atmosphere between you and a star near the horizon. However, there is no atmosphere in space to make the stars seem to twinkle. That’s why the Hubble telescope (哈勃望远镜), which is in space, can take such clear pictures of other galaxies (星系).

Go out tonight and take a look at the stars twinkling in the sky!
