Downloads
(July 30, 2019) Current version: 2.2.0
Here is a writeup on the new 2.2.0 release.
Gaia Sky 2.1.0+ can automatically download the base data and data packages.
If the program crashes, just delete your [user.home]/.gaiasky
folder in Windows and macOS, and ~/.local/share/gaiasky and
~/.config/gaiasky in Linux.

Installation instructions
Windows installer
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 onMore info and then on Run anyway.
macOS installer
Download and run the DMG file. Then follow the installer instructions.TGZ installation
Uncompress the archive in POSIX systems using:
$ tar -zxvf gaiasky-[version].tar.gz
DEB package
Run the following in a terminal:
$ dpkg -i gaiasky-[version].deb
RPM package
Run the following in a terminal:
$ rpm -ivh --nodigest gaiasky-[version].rpm
AUR package
Use any tool capable of installing packages from AUR. The package name isgaiasky. For example, with yay:
$ yay -S gaiasky
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 5131513 |
522 MB | |
| 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 6767469 |
689 MB | |
| A reasonably small dataset. Some scanning underdensities are present due to the strict bright star criterion (10%). | ||||
| Default | 20% / 0.5% | 7.5 million 7573285 |
771 MB | |
| 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 7741020 |
788 MB | |
| Contains only bright stars with parallax relative errors up to 90%. No faint stars (gmag > 13) are included. | ||||
| Large | 50% / 12.5% | 97 million 96946779 |
9,1 GB | |
| 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 400491674 |
37 GB | |
| This is a rather large dataset. Contains four hundred million stars, up to 50% parallax relative error. | ||||
| Very large | 90% / 90% | 601 million 601336710 |
47 GB | |
| 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 1331910533 |
56 GB | |
| 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. | ||||
| RUWE | RUWE | 92 million 92082185 |
8.6 GB | |
| Catalogue with 92 million stars where the Re-normalised Unit Weight Error (RUWE) < 1.4. See this. | ||||
Isosurface maps
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).
| File | Description | Size |
|---|---|---|
| Very ionizing | Very ionizing hot stars | 15 MB |
| Some ionizing | Some ionizing hot stars | 16 MB |
| Non-ionizing | Non-ionizing hot stars | 18 MB |
| Non-medium-ionizing | Non-medium-ionizing hot stars | 33 MB |
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 ~/.local/share/gaiasky/data (Linux).
- Hi-res texture pack - Version 1.5.0
- Hi-res texture pack - Versions 2.0.0 and 2.0.1
- Hi-res texture pack - Versions 2.0.2 and 2.0.3
- Hi-res texture pack - Version 2.1.0+
