An overview of Google Earth

Michael "Doc" Callahan kicks off our 10-part series on Google Earth with an overview of the desktop world navigator. Google Earth has continually improved since it first came out; you can study the geography of the Earth, look look into the seas and gaze upon the stars above your head. You can look at things from space or from as closeup as "street view." This 10-part series will give you a peek at just some of the things Google Earth can do.
