STEVE EMBER: Some planetariums use film projections. More technologically advanced planetariums use digital systems controlled by computers. Digital technologies offer planetariums many choices. These theaters can show movies about space. Or, these planetariums can serve as classrooms where live interactive presentations take place. For example, astronomers can guide viewers on a trip around the universe using image databases with real information about the placement of stars and planets.
BARBARA KLEIN: The Smithsonian National Air and Space Museum in Washington, D.C. has both a digital system and a projector system made by the Carl Zeiss company.
This Zeiss Model VI was a gift to the museum from West Germany in honor of the United States’ two hundred year anniversary. Last week, we attended a live show called “The Stars Tonight.” Astronomer Bill Dedmond showed visitors the night sky as the season changes from summer to fall.
BILL DEDMOND: “See, that’s how night sky is supposed to look. You can see thousands of stars when you are away from the city light pollution. You can even see this bright band of light here all the way across the sky. What is that bright band of light?”
KIDS: “The Milky Way!”
BILL DEDMOND: “OK, Excellent!”
STEVE EMBER: Bill Dedmond talked about the groups of stars or constellations in the night sky. He pointed out an important constellation, the Big Dipper. If you can find this group of stars, you can easily find the North Star, or Polaris. Mr. Dedmond also gave viewers a tour of the planets.
