The world’s largest radio telescope was finished on Sept. 25, 2017 in China.

FAST is a five-hundred-meter telescope. It is also called Tian-yan ("The Eye of Heaven"), with a dish the sire of 30 football grounds, deep in the mountains of southwest China's Guizhou Province. The giant dish is built on a howl-like valley.

The surrounding area has "radio silence" as there are no towns and cities within a 5-kilometer radius(半径范围) and only one county center within 25 kilometers.

FAST is made up of 4,450 panels(面板). The second largest radio telescope is in Russia. The bigger dish will be able to pick up weaker signals (信号).

The radio telescope is like an ear, listening to tell meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy(银河系) and explore the origins(起源)of the universe. "Any of its discoveries will lead to a Nobel Prize," said Joseph Taylor, a Noble Prize winner.

The FAST project began in 2011. And the telescope is expected to remain the global leader for the next 10 to 20 years.

You may have heard the saying, women are from Venus(金星) and men are from Mars (火星). It's a nice way of saying how men and women are quite different from each other in many ways.

These differences can be seen everywhere, even in how we communicate with friends. A recent study by the University of Oxford suggested that men and women keep relationships with friends far away in different ways.

Researchers questioned 30 students about their friendships just before they left for college. They followed up the questions nine months, and then 18 months later Robin Dunbar, who headed the research, told that how long friendships among women last depended on whether they made an effort to talk more to each other on the phone. Men, on the other hand, tended to (倾向于) do things differently. They went through months of not being with friends by planning meet-ups (见面) sometimes. This was the biggest difference between men and women.

Of course, gender (性别)isn't the only thing that influences how we stay in touch. The way we keep our friendships also depends on the preference(偏好) of each person, and it can take a while to find your own way of making your friendships work. One thing that is pretty clear though is that friends who make the effort to keep in touch, even if it's only through Wechat(微信)once a week, do tend to stay friends, no matter how far it is.
