Did you know that the constellations are really inventions of the imaginations of people, scientists, farmers, poets and astronomers, for thousands of years?  The reason we name certain groups of stars is because it helps people identify them, and therefore they can use them to navigate or find their way. Every star has a name, a size and a brightness; but there are so many that it would be impossible to find them if we did not have a way to help us find them in the dark night sky.  On line you can find the lists of all the constellations, and interesting information about them.  Here are some good links to help you identify these star shaped in the heavens.  http://www.astro.uiuc.edu/~kaler/sow/  ON this site if you click on the name of the constellation or the star, the site will open an appellate to show you how that star or constellation looks in the night sky. http: http://www.astro.wisc.edu/~dolan/constellations/
