SpaceEngine

## About This Game
SpaceEngine is a 1:1 scale science-based Universe simulator, featuring
billions upon billions of galaxies, nebulae, stars, and planets, all shown at
their full real-world scale. Explore Earth and our neighboring worlds in the
Solar System, orbit a black hole in a galaxy billions of light-years away, or
visit anything in between seamlessly, with no transitions.

All of time and space are yours to explore - cruise between the stars at a
million times the speed of light, and accelerate time to watch the orbital
motions of a thousand worlds play out before your eyes. Every planet you
encounter in your journey will feature procedural 3D terrain with detailed
textures. Everything you see in the sky - stars and galaxies, planets and
moons, asteroids and comets, black holes and neutron stars, star clusters and
nebulae - are yours to explore at the press of a button.

Spacecraft with Newtonian physics and pilot-assist autopilot features (in
early development but fully usable) are yours to fly anywhere in the universe
in the Flight Simulator mode. SpaceEngine is also very friendly for creators
of mods and add-ons - create your own planets, star systems, even galaxies,
import your own spacecraft models, create custom GUI skins, and more, all
easily sharable with others.

With SpaceEngine, the possibilities are limitless.

SpaceEngine Planetarium capabilities:

* Astronomy
All types of celestial objects are represented: galaxies, nebulae, stars and
star clusters, planets and moons, comets and asteroids. Known celestial
objects are represented using data from catalogs: galaxies (NGC/IC), stars
(HIPPARCOS), star clusters, nebulae, and planets (Solar System and known
extrasolar planets). Regions of space not yet cataloged feature procedurally
generated objects: galaxies, stars, star clusters, nebulae, and planetary
systems.
* Controls
You are free to move around the universe - travel seamlessly between any
object and any distance, from surface to orbit to interstellar and
intergalactic space. Moving through space is as easy as "click and go", as
well as game-style free flight using the WASD keys or a gamepad. Also, time
travel is possible: you can accelerate, decelerate, or reverse the flow of
time, and jump to a specified date. Detailed interactive tutorials will
familiarize you with the controls.
* Graphics
Volumetric 3D models of galaxies and nebulae with interstellar dust clouds,
and 3D landscapes on planets and stars. For many Solar System bodies, actual
data from space probes is used, with huge, high-resolution texture packs
available as free DLC. For unmapped and procedural planets, the surface is
generated procedurally using your computer's GPU. Other features include
realistic atmospheric scattering, eclipse shadows, animated auroras and comet
tails, and physically-based light warping near black holes and neutron stars,
with animated accretion disks and jets.

* Physics
Realistic and physically-based generation of procedural objects (galaxies,
star systems, planets) and their physical properties (mass, radius,
temperature, atmospheric parameters, etc). The orbital motion of planets,
moons, and stars in multiple-star systems are accurately calculated and
displayed. Realistic space ship design concepts and physics: orbital motion,
atmospheric flight model, and Alcubierre warp drive physics.
* Virtual reality
SpaceEngine supports HTC Vive, Oculus Rift (via native library), and Windows
Mixed Reality (via Steam VR). Support of VR controllers is partial: you can
select objects with one controller and move around with the other one. Please
note that VR support is still a work in progress, and new users should become
familiar with the program in 2D before trying to use VR.
* Sound
Original background music tracks made by many authors, with context-sensitive
playback. Sound effects for planetary environments and space ships are in
development.
* Tools
Built-in tutorials will help you start using the Planetarium. Search for
celestial objects by name and search for the nearest star systems. Browse the
cosmos using a scalable Universe map and planetary system chart. Saving,
exporting, and importing of locations is supported, which can easily be shared
between users. The program keeps an automatic journal of objects you have
recently visited. Learn every detail about the objects you find using the
built-in "Wiki" info system, with additional hand-written descriptions of many
known objects. Display the orbital paths of celestial objects, labels and
markers, constellations, and other informational tools.
* Multi-language support
Currently SpaceEngine is available in English, German, French, Italian,
Spanish, Dutch, Finnish, Swedish, Croatian, Czech, Polish, Russian, and
Catalan languages. Many new localizations are under development. Only
localizations which are 100% complete are displayed on the Steam store page,
but you can enable others in-game.
* Modding
SpaceEngine supports creating and importing user add-ons: catalogs, models and
textures for deep space objects, planets, and space ships. Spacecraft models,
representing both real and fictional designs - including from popular sci-fi
franchises - are commonly imported and shared by the community, both here on
Steam and on the official SpaceEngine forum.
