Gaia Sky

02/08/2017 - Version 1.5.0 of Gaia Sky is now out!

Gaia Sky is a real-time, 3D, astronomy visualisation software that runs on Windows, Linux and macOS. It is developed in the framework of ESA's Gaia mission to chart about 1 billion stars of our Galaxy in the Gaia group of the Astronomisches Rechen-Institut (ZAHUniversität Heidelberg).


  • Free and open source - The application is free and open source and will stay this way. You can even contribute to the development or the translations.
  • From Gaia to the cosmos - Move freely through the cosmos and descend to the surface of any Planet or do a close-up inspection of Gaia. All movement and transitions are seamless!
  • Gaia - Observe Gaia in its orbit and discover its movement in the sky and its attitude.
  • 3D ready - With 5 stereoscopic modes: Anaglyphic (red-cyan), VR headset, 3DTV, cross-eye and parallel view.
  • Planetarium projection mode - Ready to produce videos for full dome systems.
  • Use your own data - Comes with TGAS, NBG and SDSS. Supports VOTable, FITS, CSV and all formats accepted by STIL.
  • Navigate the galaxy - Support for controllers and gamepads makes navigating the Galaxy a piece of cake.
  • Record and play your camera paths - Ready to record and play camera paths off-the-shelf.
  • Scriptable and extensible - Use Python to script and extend the capabilities of the Gaia Sky.
  • Internationalised - Translated so far to English, German, Spanish, French, Catalan and Slovenian.
