A telescope, called Gaia, is being designed by astronomers in Europe, and it couldn’t be more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids (小行星) and comets headed for Earth, Gaia will be looking at our entire galaxy (银河系).

Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia’s map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe (观察) about a billion stars and other objects in our galaxy. Each object will be observed about 70 times.

Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle (角度). These two telescopes act like Gaia’s “eyes”. The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views.

Gaia, which is to be sent into space, will be a powerful telescope. If you were to use it on Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair.

Gaia is one of more than a dozen telescopes being designed by scientists right now. The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe, with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes.

1.How many different angles can Gaia focus at each time?

“You will be in my heart forever. Without you, there are only emptiness and desert in my life...” This is a line from a heartfelt poem Feng Duan wrote to his fiancee Chen Lianfang in 1955.

Feng is now 94 and Chen 90, and they have been married for more than half a century. Feng, an academic at the Chinese Academy of Sciences, may not be a professional poet but for 64 years, Feng has written countless love poems to his wife. On every important anniversary or festival, Feng would send a poem to Chen. In 1978, when Chen’s cancer surgery succeeded, Feng created more than ten poems to celebrate his wife’s recovery. Chen used a red suitcase to store these love poems. The academic has also translated many English, French and German poems into classical Chinese.

The couple was introduced to each other by a common friend in 1953 and Feng sent two paper copies of poems to Chen as a gift.

“As long as I think of you, a beam of sunshine lights up my heart,” Feng wrote.

Chen recalled the first time Feng invited her to his dormitory to have a cup of tea and she thought the cup was made of frosted glass. As the two became closer, Chen often visited the academic’s dorm. She realized that the cup was the only one poor Feng owned. The opaque (不透明的) cup was not frosted glass but common glass stained with toothpaste.
