Simulated Sky

For centuries, the rich nocturnal environment of starry sky could be modelled only by analogue tools such as paper planispheres, atlases, globes and numerical tables. The immersive simulator twentieth century, optomechanical planetarium, provided new ways for representing teaching about sky, but high construction running costs meant that they have not become common. However, in recent decades, "desktop planetarium programs" on personal computers gained wide attention. Modern incarnations are immensely versatile tools, mostly targeted towards community amateur astronomers knowledge transfer transdisciplinary research. Cultural also value possibilities give simulating skies past times or other cultures. With this paper, we provide an extended presentation open-source project Stellarium, which last few years has been enriched with capabilities cultural astronomy research found similar, commercial alternatives.
