If you are fascinated by the night sky, this free application will allow you to explore the stars, planets and constellations from the comfort of your computer.
1. Go to stellarium.org and download the open-source software, available for Windows, Macintosh or Linux operating systems. You'll also want to download the PDF user's guide. Once the program is installed, open it and set your location.
2. To set location, press the F6 button. Click on map or search to see if your town is listed. The most accurate way to find your location is to insert your exact longitude and latitude. Find it by typing your address into stevemorse.org/jcal/latlon.php.
3. There are many cool things you can do with stellarium: watching the light change in real time as the sun rises, viewing constellations and nebulas with one click and removing the atmosphere if you want to watch the stars move during the day.
