Gaia Sky is a libre and open-source astronomy visualisation desktop and VR program with versions for Windows, Linux and macOS. It is created and developed by Toni Sagristà Sellés in the framework of ESA's Gaia mission to create a billion-star multi-dimensional map of our Milky Way Galaxy, in the Gaia group of the Astronomisches Rechen-Institut (ZAH, Universität Heidelberg). Gaia Sky is a product of the outreach working group of the Gaia Data Processing and Analysis Consortium. The software is released under the Mozilla Public License.
The inner workings of Gaia Sky are described in detail in the paper Gaia Sky: Navigating the Gaia Catalog.[2]
Gaia Sky is used by ESA to aid in the video production of Gaia Data Releases.[3] A video made with Gaia Sky was also featured in the Astronomy Picture of the Day website.[4]
Data
The installer packages of Gaia Sky contain the program but no data at all. In order to use Gaia Sky, at least a download of the base data package, containing the Solar System with low-resolution textures, is necessary. Gaia Sky offers a built-in download manager which connects to the servers at the Astronomisches Rechen-Institut in Heidelberg to fetch the desired datasets. The downloading and deploying processes are seamless to the user.
Several datasets are available, offering higher resolution textures, different cuts of the Gaia DR2 catalog (up to 1.3 billion stars), other star catalogs such as the Hipparcos catalog, different galaxy maps (dust, HII regions, etc.), nebulae or extragalactic catalogs such as NBG[5] or Sloan Digital Sky Survey.
All datasets are specified in JSON files following a comprehensible and well documented format.[6]
