Google Earth

Google earth is a cool program that works like an interactive map. You can use it to look up any zip code and it will "fly" there. You can look up your own town and even your own street with ease. It uses satellite imagery to look at places and I like how I don' have to use Google maps, because it is a standalone program. There is another cool feature call sky mode with which you can look at constellations, stars, and galaxies. I would advise to check out this free program from Google and the partnership of the Space Telescope Science Institute.
