Oh you remember when you were young and you had that little telescope where you spend hours and hours at night looking at the sky? Well, now you don't need to do that anymore. You can get all these information online at Sky-Map. They have created an extremely detailed skymap with tons of information about the stars and other space bodies. Furthermore, anyone can comment or even edit the information on their system, making it very interactive. Check out their "Getting Started" guide if you are a bit confused about the site.
