Understanding the Zodiac Constellations

      A NEW LIVE planetarium show will be presented on Thursday, March 21, at 6 PM at the Hollidaysburg Planetarium.  This family show (suggested minimum age 10-12 and up) will be presented in the traditional planetarium style using many of the new planetarium’s features!
      The stars, planets, and constellations of the current evening sky will be presented with the best of the winter sky zodiac constellations. Topics will include:
  Why are the zodiac constellations so special?
  How did we get the zodiac constellations?
  Why is Aries usually listed first when reading your horoscope?
  What is the third motion of the Earth (besides rotation and revolution)?
  Did we always have a North Star?
      With the new planetarium, we can travel back several thousand years and see where the constellations were at that time and how they have changed.  This is an original script presented by Fred Marschak.
Tickets are $4 for adults and $3 for students. Pay at the door.

      Also, on 3/21,visitors have a choice between the 6 PM live show, ‘Understanding the: Zodiac Constellations’ or the continuing fulldome movie, ‘Incoming’ at 7 PM.  Asteroids, Comets, and the Hard-Hitting Stories of Our Cosmic Origins  Narrated by George Takei.  Suggested minimum age is 8-10 and up.
Discover what impacts from above can teach us about the history of our planet, the solar system, and the universe!
      Asteroids and comets have collided with our planet throughout its history, changing the course of life on Earth and shaping the world we know today.
Incoming!, the original planetarium show from the California Academy of Sciences, explores the past, present, and future of our Solar System and the landmark discoveries scientists have made sending spacecraft to visit tiny worlds. Cutting-edge visualizations bring real-time data from current NASA missions to life while taking audiences on a ride through the dynamic story of our cosmic origins. Along the way, audiences discover what these impacts from above can teach us — and how scientific advances may allow us to find and track cosmic threats before they reach planet Earth.
      The show opens with a lizard's-eye view of the Arizona desert and the Barringer Meteor Crater. This scar on Earth's surface formed almost 50,000 years ago when an asteroid smashed into the landscape and vaporized on impact. Barringer is one of about 200 impact sites, including the one that gives clues about the demise of the dinosaurs — and how a far-traveling visitor from space transformed life on Earth
