THE BRONX - Students at Harry S. Truman High School can now view the universe in a whole new way, thanks to the school's newly renovated planetarium. Asteroid showers and shooting stars wowed the students at the dome's unveiling today. The celestial experience has gotten a major upgrade because the new system uses a high-powered digital projector. Students say it's like seeing space in 3-D. Bronx Borough Presiednt Adolfo Carrion and some Truman alums were on hand for the planetarium's inaugural viewing today.
