Text, MYTH versus REALITY 

Myth side 

Text, All galaxies are the same. 

Reality side 

Text, The shapes of galaxies vary -- some are spiral, some are elliptical, and some have no definite shape. Galaxies also differ in color, composition, orientation, age, size, the number of stars within them, and distance from Earth.
