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 (令人头晕眼花的) .

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.
