1. Seeing Stars

   • When you look up into the sky and then again later the same night You should see many of the recognisable patterns as before, but they have moved to a different position in the sky.
     • From this simple observations it is easy to conclude that the sky is a crystal-clear sphere dotted with tiny lights we call stars.
       • This "celestial sphere" seems to rotate above our heads, carrying with it the fixed patterns or constellation of gleaming stars.
         • Constellations:: groups of stars that were given a particular name because of the shape the stars seem to form in the sky when viewed from earth.
