Stellarium: A Stellar Application
Stellarium is a fantastic, free, open-source sky show program. The graphics are outstanding, the data on sky objects amazing, and there are some awesome surprises.
There are many sky show applications. I hesitate to use the term “planetarium” only because that may scare away people who think it’ll be too technical or nerdy. It is, in fact, a fun and beautiful program. How the program looks depends on the time of day you first run the program.
That’s one of the first surprises. Stellarium doesn’t just present a screen full of black salted with white dots. The first graphic shows how the sky might look from my location (Farmington Hills, MI) at about 8:30 p.m. on March 31, 2007. The sky glows a lush orange from the twilight in the south. Check out how the orange becomes more prominent as you look to the west. In the application, you can do a 360 and see how the stars become more visible as they’re further from the twilight.
The program is highly customizable. You can turn “atmosphere” on or off. The next picture shows the previous scene with the atmosphere off. Now you can appreciate the full glory of the sky.
