Download the installer and double-click on it. Follow the on-screen instructions. In Windows 8/10 SmartScreen may block the installation. If so, just click on More info and then on Run anyway.

AUR package

Use any tool capable of installing packages from AUR. The package name is gaiasky. For example, with trizen:

Additional Gaia DR2 catalogs

Here you can find larger catalogs for download, based on Gaia DR2 data. The 'criteria' column contains the two selection criteria used in the catalog, for bright (gmag <= 13) and faint (gmag > 13) stars in parallax relative error. The Default catalog already comes bundled with Gaia Sky.

Download the desired catalog and extract it in the gaiasky/data/octree/dr2/ folder (create if it does not exist). Then download the catalog descriptor json file and put it in gaiasky/data. Finally, go to the preferences window in Gaia Sky, choose the new catalog under the Data tab and restart.

These datasets will be available on April 25, around 12:00 CEST.

Data Criteria Number of stars Size Catalog descriptor
Default 20% / 0.5% 7.5 million (7574316) 768 MB catalog-dr2-default.json

Very large 90% / 90% 670 million aprox. ??? GB catalog-dr2-verylarge.json

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 download with 4K and 8K textures which must be extracted in $GAIASKY_INSTALL_DIR/data/tex.
