Release candidates repository – Release candidates are usually testing versions published before a release is made in order to help iron out bugs and problems. You can try them out and report bugs if you encounter them.
(September 10, 2019) Current version: 2.2.1
Gaia Sky 2.2.1 is the first official version to support VR!
Use the CLI argument
gaiasky -vr or use the
gaiaskyvr.exe executable (on Windows)
to run it. You need an HDM supporting OpenVR.

macOS installerDownload and run the DMG file. Then follow the installer instructions. Our package is not signed, so you may want to have a look at how to open apps from "unidentified developers".
TGZ installationUncompress the archive in POSIX systems using:
$ tar -zxvf gaiasky-[version].tar.gz
DEB packageRun the following in a terminal:
$ dpkg -i gaiasky-[version].deb
RPM packageRun the following in a terminal:

AUR packageUse any tool capable of installing packages from AUR. The package name is
gaiasky. For example, with
$ yay -S gaiasky
How to run...
- Gaia Sky
- Use the shortcut provided by your Operating System, or use the
$ gaiaskycommand from your favourite CLI.
- Gaia Sky VR
- Use the 'Gaia Sky VR' shortcut in the start menu or
$ gaiasky -vrfrom CLI.
Base data package
In order to run Gaia Sky you need to download the base data package, containing the essential data to run the software (planets, moons, etc.). Usually, the base data is selected and downloaded automatically at startup if it is not found. However, if you require a manual download, you can get it here:
Gaia DR2 catalogues (version 2.1.0+)
Latest update: 2019/02/18
Here you can find larger catalogues for download, based on Gaia DR2 data. The 'criteria' column contains, unless otherwise stated, the two selection criteria used in the catalogue, for bright (gmag <= 13) and faint (gmag > 13) stars in parallax relative error.
These catalogues can also be downloaded directly with the download manager from within Gaia Sky, or manually via these server pages.
Download the desired catalogue and extract it into your data folder (
[user.home]/.gaiasky/data in Windows and macOS,
~/.local/share/gaiasky/data in Linux). That's it, you are done!
|Data||Criteria||Number of stars||Size (compressed)|
|Very small||5% / 0.5%||5.1 million
|A very small dataset. Scanning underdensities are clearly visible due to the very strict bright star criterion (10%). Otherwise, a good dataset to explore without filling up your disk.|
|Small||10% / 0.5%||6.7 million
|A reasonably small dataset. Some scanning underdensities are present due to the strict bright star criterion (10%).|
|Default||20% / 0.5%||7.5 million
|This is a useful first catalogue to try out. The catalogue is a trade-off between number of stars and size. Contains bright stars with parallaxes up to 20% relative error, and faint stars with 0.5% relative error.|
|Bright||90% / 0%||7.7 million
|Contains only bright stars with parallax relative errors up to 90%. No faint stars (gmag > 13) are included.|
|Large||50% / 12.5%||97 million
|This is the default large dataset. Contains about a hundred million stars, with a 50% relative error for bright stars and 12.5% for faint stars.|
|Rather large||50% / 50%||400 million
|This is a rather large dataset. Contains four hundred million stars, up to 50% parallax relative error.|
|Very large||90% / 90%||601 million
|Lots of stars (601 million) in this dataset. Parallax criteria are very relaxed, at 90% relative error for both bright and faint stars.|
|Extra large||Bayesian distances||1.33 billion
|Catalogue with 1.33 billion stars (all 5-parameter sources in DR2) based on the bayesian distances paper by Bailer-Jones et al.. We are still working on getting a good artifact-free LOD structure with this catalogue, so bear in mind this is not the final product.|
|Catalogue with 92 million stars where the Re-normalised Unit Weight Error (RUWE) < 1.4. See this.|
Here you can find additional isosurface maps produced by Galaxy Map ready to use with Gaia Sky.
Just extract the packages in your data folder (
[user.home]/.gaiasky/data in Windows and macOS,
~/.local/share/gaiasky/data in Linux).

High resolution texture packs
The installation packages do not include high resolution textures to keep the file size at bay. However, we offer a high resolution
texture pack with 4K and 8K textures which must be extracted in
[user.home]/.gaiasky/data (Windows and macOS) and
