Explore the Cosmos with SpaceEngine: The Ultimate Universe Simulator

Embark on an unparalleled journey through the universe with SpaceEngine, a groundbreaking 1:1 scale science-based universe simulator. Explore billions of galaxies, breathtaking nebulae, radiant stars, and intricate planets, all rendered at their full, real-world scale. Seamlessly traverse from the familiar landscapes of Earth and our Solar System to the enigmatic depths surrounding a black hole billions of light-years away, experiencing a universe without loading screens or transitions.

With SpaceEngine, all of time and space are at your fingertips. Cruise effortlessly between stars at unimaginable speeds, witness the intricate dance of orbital mechanics unfold before your eyes as you manipulate time. Every planet you encounter boasts procedurally generated 3D terrain with stunning, detailed textures. From shimmering stars and distant galaxies to rocky asteroids, swirling comets, and mysterious neutron stars, the entire cosmos is yours to explore with the simple press of a button. Discover the magic of Astronomy in an immersive detail.

Pilot realistic spacecraft governed by Newtonian physics and augmented with pilot-assist autopilot features (currently in early development but already fully functional) in the Flight Simulator mode, offering you the freedom to navigate any corner of the universe. SpaceEngine also shines as a platform for modding and customized add-ons. Craft your own planets, design unique star systems, and even build entire galaxies. Import your own spacecraft models, create stunning user interface skins, and share your creations effortlessly with the thriving community. Share your love of space exploration and learn with others!

The possibilities within SpaceEngine are truly limitless, offering a unique blend of realistic simulation and boundless creativity.

SpaceEngine Planetarium Features:

Astronomy: All types of celestial objects are meticulously represented, including galaxies, nebulae, stars, star clusters, planets, moons, comets, and asteroids. Known celestial objects are faithfully recreated using data from a comprehensive array of catalogs, including NGC/IC for galaxies, HIPPARCOS for stars, and detailed planetary data for our Solar System and known extrasolar planets. Uncharted regions of space are brought to life with procedurally generated objects, ensuring a universe that is both realistic and endlessly explorable.

Controls: Navigate the universe with unparalleled freedom! Travel seamlessly between any object and any distance, from planetary surfaces to interstellar and intergalactic space. "Click and go" navigation makes exploration intuitive, while game-style free flight using WASD keys or a gamepad offers precise control. Manipulate time to accelerate, decelerate, or reverse its flow, and even jump to specific dates. Comprehensive interactive tutorials will guide you through the controls, ensuring a smooth learning curve.

Graphics: Immerse yourself in stunning visuals, featuring volumetric 3D models of galaxies and nebulae with interstellar dust clouds, alongside detailed 3D landscapes on planets and stars. Actual data from space probes provides incredibly realistic textures for many Solar System bodies, with massive, high-resolution texture packs available as free DLC. For uncharted and procedural planets, the surface is generated dynamically using your computer's GPU. Experience realistic atmospheric scattering, dynamic eclipse shadows, animated auroras and comet tails, and physically-based light warping near black holes and neutron stars, complete with animated accretion disks and jets.

Physics: Experience a universe governed by 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 is accurately calculated and displayed. Delve into realistic spacecraft design concepts and physics, encompassing orbital motion, atmospheric flight models, and even Alcubierre warp drive physics.

Virtual Reality: Immerse yourself fully in SpaceEngine with support for Oculus (via native library) and SteamVR (HTC Vive, Valve Index, WMR, and other headsets). VR controller support allows you to select objects and navigate the cosmos intuitively. Note that VR support is continually being developed, and new users are advised to familiarize themselves with the program in 2D before venturing into VR.

Sound: Enjoy an immersive audio experience with original background music tracks crafted by various artists, featuring context-sensitive playback. Sound effects for planetary environments and space ships are currently in development, promising an even more engaging experience.

Tools: Built-in tutorials will quickly get you started with the Planetarium. Search for celestial objects by name or locate the nearest star systems. Explore the cosmos using a scalable Universe map and planetary system chart. Save, export, and import locations to easily share them with other users. SpaceEngine automatically keeps a record of recently visited objects. Learn fascinating details about celestial objects using the built-in "Wiki" info system, featuring hand-written descriptions of many known objects. Display orbital paths, labels, markers, constellations, and other informational tools to enhance your exploration.

Multi-language Support: SpaceEngine is currently available in a wide range of languages, including English, German, French, Italian, Spanish, Dutch, Finnish, Swedish, Croatian, Czech, Polish, Ukrainian, Russian, Catalan, Chinese, Japanese, and Korean. New localizations are continuously being developed. Only fully completed localizations are displayed on the Steam store page, but you can enable others within the game.

Modding: Unleash your creativity with SpaceEngine's extensive modding support. Create and import user add-ons, including 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 frequently imported and shared by the community on the Steam Workshop.
