Taking a queue from the amazing Starry Night software package, Google introduced Google Sky today. Google Sky is part of the latest edition of Google Earth and allows you to see stars, planets, constellation diagrams, satellites, and all sorts of other astronomy-related information right on your computer screen. Best of all, it's free! While not as graphically appealling or as robust as Starry Night, it's a great first crack at it by Google. This is a wonderful resource for introducing people to astronomy and for teachers to use. I'm sure that Google will continue to expand on it and make it an even more impressive resource.
