I just read on BBCool about a new free application for BlackBerry devices that allows you to view all the constellations, planets, and stars that you should be able to see from your current location. The software just has you punch in your location (via postal/zip code or lat/long) and it will show you a graphic image of the sky and the constellations that are visible. You can read more about Starry Night here or you can download the application for your BlackBerry from this location. The application is kind of clunky but I will definitely be trying it out tonight.
