Stellarium is a powerful program for Windows created to help you explore planets and constellations in a three-dimensional environment. The software solution serves as an open-source planetarium and provides detailed information about celestial objects, simulates solar and lunar eclipses, as well as displays the Milky Way.

Explore space

After launching the application, you are greeted with a full-screen overview of the sky. With just one click, you can learn more about selected objects. It is possible to view type, magnitude, galactic longitude and latitude, as well as parallax, distance and angle.

In contrast to Cartes du Ciel, all objects may be viewed by using a telescope. What is more, you have the ability to customize it in terms of name, focal lengths and diameter. You can also pick a location on the map and specify either geographical coordinates or country and jump to it.

Discover past constellations

Another advantage of using this utility is the possibility to travel back in time and see the positions of constellations and other details. In order to access this feature, you need to set the date and time in the dedicated dialogs, and the program will automatically generate appropriate projections.
