Stellarium – virtual planetarium on the computer

Stellarium is a free program for observing the sky, it is a computer virtual planetarium for astronomy lovers. Stellarium displays the sky in 3D, as it is visible to the naked eye, binoculars or a telescope from a specific point on Earth or from the planets of the solar system.

In the modern world, especially for residents of large cities, it is not always possible to see the starry sky that is not covered by buildings or the surrounding landscape. The Stellarium program will replace an amateur telescope for observing space objects from a computer screen.

Watching the starry sky in Stellarium

When you first start the Stellarium program, the PC screen displays a glade corresponding to the season, with a starry sky in real time. If it is daytime, then you will not see stars here, but only the solar disk in the sky. However, in the application, you can speed up time or look at the sky as it was, for example, last night.

By default, the Stellarium window opens with a view of the starry sky at the current time, displayed from one rural locality in France – the homeland of the author of the program.

You need to choose your location. You can do this in the following way:

  1. Move the mouse cursor to the lower left edge of the program window.
  2. A triangular-shaped control panel will open with various Stellarium settings.
  3. Click on the top “Location Window” icon (alternatively, press the “F6” key), and then select your option.

The control panel contains buttons for controlling the program functions, from here you can enter the application settings.

Select the type of program, the order of astronomical calculations, eyepieces and other functions.

The necessary actions in Stellarium are quickly performed using the keyboard keys. Hot key combinations are listed in the Help window, which is called up by pressing the F1 key.

In order not to search for the necessary stars, planets or constellations in outer space for a long time, use the built-in search services. Calling the window for searching for celestial bodies is carried out using the “F3” key. Enter the name of the object or its location, search the list.

To display objects from the Messier catalog, you must use the Latin alphabet. For example, to look at the Andromeda Galaxy (Andromeda Nebula), you need to enter the name of the object in English “M 31” into the search box.

The upper left part of the screen displays detailed information about the selected object: absolute magnitude, distance to the Earth, spectral class, and more.

Stellarium has the ability to enable the display of constellations in the starry sky in different views. For example, show images in a similar way, or display only constellation lines.

Approach or removal of space objects in the Stellarium program window is carried out using the mouse wheel.

If you select a planet of the solar system for observation, and then zoom in, the celestial object will begin to move in the program window in real time, and quickly disappear from view. To keep track of the selected object, press the space bar.
