What are Constellations?

Discipline: 

Away from city lights on a clear, moonless night, the naked eye can see 2000-3000 stars. As you look at the stars, your mind may group them into different shapes of patterns. People of nearly every culture throughout history have looked at the stars and given names to shapes they saw and invented stories to go with them. The pattern that the Greeks named Orion, the hunter, was seen by the ancient Chinese who called it a supreme warrior named Shen. The Chemehuevi Native Americans of the California desert saw the same group of stars as a line of three sure-footed mountain sheep.
