A good way to learn more about the consellations is to use Google Sky for Google Earth, web-based Google Sky, or Stellarium, which are all free, to look at the constellations. You can turn on and off the constellations and zoom around the sky to find as many as you want. If you would like to learn more about a particular constellation, search for it in Wikipedia where you can learn about the stars in it, its history and mythology.
With Google Sky for Google Earth you can click on each of the stars in a constellation to get more information about each one including the history of its name, its surface temperature, type of star, and distance from Earth. Although the stars in a constellation appear close to each other in the sky from Earth, they are not necessarily close to each other in the universe and are often very different types of stars and other objects.
Stellarium gives information about each object in a constellation including the name, type, magnitude, location and distance. It also has a constellation art button you can turn on and off to help you visualize the characters the Greeks imagined in the sky.
