add the skill to your arsenal.

It’s always within one degree of true north. So use the Big Dipper and Cassiopeia are your guides. Look at the Dipper’s ladle and pretend you’re

pouring soup from it. The flow of that space soup will point straight to the North Star..

The Constellation of stars

A constellation is an internationally defined area of the celestial sphere. These areas are grouped around patterns that represent the

shapes that give the name to the constellations. When astronomers say an object is "in" a given constellation, they

mean it is within the boundaries of one of these defined areas of sky.
