About Gaia Sky

Gaia Sky is an astronomy visualization platform for desktop and VR that runs on Linux, Windows 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 (ZAH, Universität Heidelberg). Explore the Solar System, the Milky Way, and even the most distant galaxies of our Universe with up-to-date, real scientific data.

Release info Update on Oct 22, 2026
Release notes This is a bug-fix release. It restores the occlusion of the procedurally generated galaxy channels by the volume dust, and fixes several issues that surfaced when creating galaxies from the UI and when inserting entities into the scene graph.

• Half-resolution channels are occluded by full-resolution occluders again.

• Runtime-created billboards bind their texture array correctly.

• Galaxies added via the UI get their parent populated correctly again.

• Fix the guard in the code that adds children to nodes, which made it function improperly. This prevents a crash with the NASA Exoplanet Archive dataset.

• Always run the volume depth pre-pass at full resolution, so that its depth occludes half-resolution content, and skip the full-to-half depth blit when the half-resolution pass is empty.
