In the huge universe, there is the Galaxy and many other galaxies. In the Galaxy, there is the Solar System and lots of other stars. In the Solar System, there is the sun, the earth and seven other planets. As we know, the eight planets go around their star- the sun. In our ...

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 ...
根据第二段"However, there is no atmosphere in space to make the stars seem to twinkle. That's why the Hubble telescope, which is in space, can take such clear pictures of other galaxies"(然而,太空中没有大气层去使星星看起来在闪烁。这就是为什么在太空中的哈勃望远镜可以拍摄到其他星系如此清晰...
“This is long enough for other planets to have intelligent life,” say Shostak and Barnett. The second reason is size, the universe is huge. “Tools like the Hubble Telescope (哈勃望远镜) have shown that there are at least 100 billion galaxies,” says Shostak. “And our galaxy, the ...

Tools such as the Hubble Telescope(哈勃望远镜)"have shown that there are at least 100 billion galaxies " says Shostak. And our galaxy the Milky Way has at least 100 billion stars. Some planets that circle these stars might be similar to Earth."Until recently it was hard to look for ...
A. 100 billion galaxies:1000亿个星系;B. 100 billion stars:1000亿颗星;C. about 12 billion years大约120亿年;D. the huge universe:巨大的宇宙。根据第2段第3和4句Scientists believe the universe is about 12 billion years old. “This is long enough for other planets to have intelligent life.”...
