About this game

SpaceViewer isn't another animated star chart. It's a 3D universe built from real astronomical measurements captured by the ESA Gaia satellite — the most precise star map humanity has ever made, covering over 1.8 billion stars across our galaxy.

Fly freely from the Solar System, through the star fields of the Milky Way, out toward distant galaxies and deep-space objects — all rendered from actual observational data, not artistic guesswork.

KEY FEATURES

🚀 Free 3D Flight
Drag and pinch to soar through space. Seamlessly zoom from the Solar System to galactic star clusters to nearby galaxies, with smooth inertia-based camera movement and scale-aware detail.

⭐ Real Celestial Data
Tap any star or planet to see its true distance (light-years/parsecs), brightness, surface temperature and color, spectral type, and coordinates. Solar System bodies include mass, orbital period, and more.

🌌 Multiple Scales of Content
Solar System: the Sun, 8 planets, and major moons
Milky Way: Gaia-derived star data — the heart of the app
Deep Space: Andromeda and other major galaxies, nebulae, and deep-field objects

📴 Offline After Setup
Download the star dataset once, then explore anytime without an internet connection.

🌍 Built for Everyone
No astronomy background needed — an intuitive, beginner-friendly interface with multi-language support opens up real space science to a global audience.

WHY SpaceViewer
Most space apps use stylized or imagined visuals. SpaceViewer is grounded in genuine ESA Gaia Archive observations, so every star you see and every distance you read reflects real data — scientifically accurate, beautifully rendered, and endlessly explorable.

A free tier gets you the brightest stars, the full Solar System, and major galaxies. An optional premium upgrade unlocks a higher-resolution star dataset and removes ads.

Whether you're a curious stargazer, a student, a parent looking for an educational adventure, or a lifelong space fan — SpaceViewer lets you hold a piece of the real universe in your hands.


DATA SOURCES

Star catalog: ESA Gaia Archive (https://gea.esac.esa.int/archive/) — precise positions, distances, brightness, and motion for over 1.8 billion stars, measured by the European Space Agency's Gaia satellite.
Solar System ephemeris: NASA NAIF (https://naif.jpl.nasa.gov/pub/naif/) — orbital and positional data for the Sun, planets, and moons.
