Space Engine is a free space simulator planetarium, with which you can explore the Universe in three dimensions, starting with your home planet and ending with the most distant galaxies. The studied part of the Universe is represented by real astronomical data, while procedural generation is used for unexplored areas. Millions of galaxies, trillions of stars, innumerable planets - everything is available for research. On every planet, moon or asteroid, you can land and observe alien landscapes and celestial phenomena. You can also fly interstellar ships and atmospheric shuttles.
All major types of space objects are represented: galaxies, nebulae, stars and star clusters, planets and moons, comets and asteroids.
Known objects are represented by catalogs: galaxies (NGC / IC), stars (HIPPARCOS), star clusters, nebulae, planets (Solar System and exoplanets).
In unexplored areas, procedural generation of objects occurs: galaxies, stars, clusters, nebulae, planetary systems.
Movement of the observer is not limited. The transition between any bodies, any scale occurs continuously. Flight control as in games (WASD), there are modes of movement with inertia.
Autopilot type "chose and fly": just click on the object with the mouse and press "G" to automatically fly to him.
Automatic binding of the observer to a moving object and automatic selection of the optimal flight speed.
Search for objects by name, search for stars in a given radius, a scalable map of the Universe, a map of the planetary system, preservation of locations, an autopilot log.
Built-in encyclopedia with descriptions of many well-known objects and the possibility of expansion by the user. Ability to give names and make descriptions for all objects, including procedural ones.
The movements of the planets in orbits are calculated in real time, acceleration, deceleration and inversion of the passage of time are possible.
Displays the orbits of the planets, the vectors of speed and rotation, labels, grid, pointer of the selected object, the current speed vector.
3D volumetric models of galaxies and nebulae with interstellar dust.
3D relief of the surface of the planets: for many bodies of the Solar System - real data on the results of research by space probes, for procedural ones - generation of procedural relief on the GPU.
Accurate Earth Atmosphere Model (Eric Bruneton), adapted for other planets.
Light effects: crowns, solar eclipses, shadows from rings, lighting of planetary bodies with each other.
Spaceships with the ability to control (alpha).
Original background music with context switching tracks.
Localization in many languages with the ability to add new ones.
Possibility of addition by users: models, textures, catalogs.
