Stellarium – Open Source Planetarium For Your Computer

If you are a sticky person and have boundless interest about space, then Stellarium is the perfect thing for you. A stellarium is a three-dimensional map of the stars, typically centered on Earth. Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like you see with the naked eye, binoculars or a telescope. The Stellarium team has announced the release of Stellarium version 0.11.3.

When someone clicks on a star, planet, or satellite, he/she get information on its distance from Earth and magnitude. It’s even better looking at the sky without using binoculars or telescope. It’s being used in planetarium projectors. You just need to set the coordinates. With Stellarium you can make the illusion more realistic adding atmosphere effects and views including the ground. Moreover, you can point to a star using the computer mouse and the program will show the information about that star like name, distance, magnitude and position in the sky.

Using the mouse wheel people can zoom in and take closer look at the stars. Since the program simulates its movement in real time when a person moves, so are the stars. On the other side, Stellarium lets people show or hide the constellations, its names and art, add or subtract atmosphere, trace the Azimuthal and Ecuatorial Grid, add or subtract the view of the ground and cardinal points, view or hide Nebulas, search and go to a selected object, go to red mode (night). In fact, people can even move freely around the entire sky using the mouse, and then pick a star that interests them to find out more information about it.
