WinStars is a planetarium running on computers, tablets and mobiles. It is a 3D simulator that accurately represents celestial objects at a given time. It also allows you to travel in our galaxy and its close neighbourhood. A thread dedicated to scientific news allows you to follow and display in the software the results of research currently conducted in astrophysics. New functions will be progressively added in order to convert the software into a pedagogical tool dedicated to the discovery of our Universe.
