More than a hundred adults and kids gather for the Star Party on a cold evening, chattering excitedly as they stand in the dark on a Virginia hillside. The odd thing is, no one has turned on a flashlight, and no streetlights or house lights wink(闪烁) on around them. These people have traveled to the countryside more than an hour from Washington, D. C., to get away from the glow of city lights.  That's because they are attending a star party. Star parties are gatherings where professional and amateur astronomers set up their telescopes and invite people to come learn about the night sky. Getting away from light pollution, or artificial skylight from buildings for example,  helps stargazers (看星星的人) see objects in the sky much better. At this star party, Sean O'Brien of the National Air and Space Museum’s Einstein Planetarium starts off by asking the crowd to simply look up and take in all they can see. He points out plenty of things that can be seen without special equipment. Stars, satellites, and even the Andromeda galaxy(仙女座) can be found if you know where to look. After that, several dozen astronomers offer close-up views. Each has focused their telescope on a different part of the sky. As kids take a look, the owner gives a mini-lesson. O’Brien says you can have your own star party at home and learn a lot just by paying attention to what's happening up above. 'Watch the sky as the seasons pass, and you will see that it changes,' he says. 'Or start with the moon. Notice when and where you are seeing it—maybe even in the early morning while you wait for the school bus. ' 小题1:What was it special about the Star Party ? A．It was organized by the local authority.
