The world’s largest radio telescope was finished in China.
FAST is a five-hundred-metre telescope. It is also called Tian-yan (“The Eye of Heaven”), with a dish the size of 30 football grounds, deep in the mountains of south-west China’s Guizhou Province. The giant dish is built on a bowl-like valley.
The surrounding area has “radio silence” as there are no towns and cities within a 5-kilometre radius(半径范围）and only one county centre within 25 kilometres.
FAST is made up of 4,450 panels(面板). The second largest radio telescope is in Russia. The bigger dish will e able to pick up weaker signals.
The radio telescope is like an ear, listening to 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 of the universe. “Any of its discoveries will lead to a Nobel Prize,” said Joseph Taylor, a Nobel Prize winner.
The telescope is expected to remain the global leader for the next 10 to 20 years.

DNA is in every cell ( 细 胞 ) of our bodies except for our red blood cells. It stores the information your body needs to make you who you are. Your DNA is 99.5% the same as everyone else on the planet. The 0.5% that we don't share with everyone else is the bit that makes you different.
DNA is the mysterious code ( 神秘密码 ) of life. It not only decides your gender ( 性别 ) and appearance, but also tells you about your family history, as well as your relations with people in other parts of the world.
Last fall, 20 students at Coretta Scott King Young Women's Leadership Academy in Atlanta learned more about who they are through a DNA test.
During their life sciences class, the girls took samples ( 样本) from their cheeks and sent them to Living DNA, a UK—based DNA testing company. From the test results, they learned about their ancestry ( 祖先 ) and made real-world connections to their races.
Lizbeth Islas, 12, learned about her family's Central American roots ( 根，根源 ) from her mother, who is Guatemalan ( 危地马拉人 ). She expected to share DNA with 54% of Native American people, but she was surprised to ?nd that she also shared DNA with people living in Africa and Europe.
Elianed Guzman, 13, knew little about her family except that they were from Mexico. She was surprised to learn that she also shared DNA with people in China and Japan.
The girls gathered in small groups to wait for their results. Their reactions reached from confusion to surprise. The 13-year-old Amariah Caudle said she learned that "the color of your skin can't decide where you are from."
Diahan Southard, a manager from Living DNA, helped them understand the test results. "Does it change how you see yourself?" Southard asked.
"Now I know I have family from everywhere," said Jahtmya Phillips, 13. "Does it change how you see the girls around the table?" Southard asked. "We are all sisters," said Anike Akanni-Jenkins, 13.
Laura Pena, the school's class designer, said she hopes to add DNA testing to the school's ninth grade curriculum ( 课程 ) in the future. "This is not a lesson they will forget anytime soon," she said.
