请认真阅读下面短文,并根据所读内容在文章后的空格内填入最恰当的单词. 每空格1个单词，不得用文章中的单词。
A scientist once said that studying the stars from the earth is something like looking up at the sky from the bottom of a swimming pool. Even on the clearest night the earth’s dense atmosphere will dim stars in the sky as it screens out (遮挡) 30 percent of their light. Air turbulence (湍流) causes stars to winkle. Through a telescope, the stars seem to jump around dizzily.
Because the moon has no atmosphere, astronomers are looking forward to setting up an observatory there. On the moon, there will be no clouds to obscure the view. The sky will appear dark at all times, so astronomers can work twenty-four hours a day. Because there is not air turbulence, the stars will steady through a telescope.
Because the moon is relatively near the earth, moon-based astronomers will see the stars in familiar patterns known on earth. They will not need new star maps of the sky. Stars seen from the moon will appear to move very slowly. Because the earth rotates (自转) on its axis once every twenty-four hours, earth-based astronomers see the stars hurry across the sky each night. The moon rotates on its axis only once a month. To astronomers on the moon, the stars will appear to stand almost still. Moon-based astronomers will have much more time to focus their telescopes and take time ---exposure photographs.
On the earth, man-made radio noises jam the airwaves and interfere with the reception of radio signals from certain stars. A radio telescope located on the far side of the moon will be permanently protected from such interference.
It won’t be easy to put telescopes on the moon. However, astronomers are certain the job can be done. They are convinced that the moon is an ideal place to set up an observatory.

Life on the Earth is wiped out every 27million years---and we have about 16 million years left until the next extinction, according to scientists.
Research into so-called ‘extinction events’ for our planet over the past 500 million years---twice as long as any previous studies ----has proved that they crop up with metronomic(有节奏的) regularity .
Scientists from the university of Kansas and the Smithsonian Institute in Washington DC are 99 percent confident that there are extinction every 27 million years.
In the 1980s scientists believed that Earth’s regular extinctions could be the result of a distant dark twin of the Sun, called Nemesis.
The theory was that Nemesis crashed through the Oort cloud every 27 million years and sent a shower of comets in our direction.
The Ocrt cloud is a vast belt of dust and ice that is believed to lie around one light year from the Sun and is the origin of many of the comets that pass through our solar system.
But now scientists claim that the regularity of the mass extinctions actually disproves the Nemesis theory because its orbit would have change over time as it interacted with other stars.
“Fossil data, which motivated the idea of Nemesis, now militate against(妨碍) it,” said the researchers.
The last extinctions event, 11 millions years ago, saw 10 percent of the Earth’s inhabitants (居民) wiped out.
This means there is around 16 million years until the next event takes place, although the graph shows that it occasionally the event takes place up to 10 million years early.
Asteroids(小行星) crashing into the Earth are commonly believed to be one of the main reasons behind mass extinctions like that suffered by the dinosaurs ---the Cretaceous-Tertiary (KT) extinction (白垩-第三纪灭绝事件).
The extinction wiped out more than half of all species on the planet clearing the way for mammals to become the dominant species(优势物种) on Earth.
The extinction was caused by a massive asteroid slamming into Earth at Chicxulub in Mexico.
The asteroid, which was around 15 kilometers wide, is believed to have hit Earth with a force one billion times more powerful than the atomic bomb at Hiroshima.
