Gaia Sky is a 3D Universe desktop and VR application to bring Gaia data to the masses, open source, libre.
The compute shader that generates galaxies gets more and more features. We can now design pretty cool shapes interactively.

I've been playing around with compute shaders to generate procedural galaxies in #GaiaSky on the fly. Still needs work, but it looks promising for populating distant galaxies. In the video, I spawned a galaxy next to the milky way, trying to mimic its structure with a few simple parameters. (1/3)

We've been working on a new galaxy model for Gaia Sky. It is a compromise between 'looking good' and 'rendering fast'.

We have just published the GPS Satellite Network dataset for #GaiaSky, put together by @plateauastro.bsky.social. You can get it right now from the dataset manager.

📢📢📢 #GaiaSky 3.6.10 is now available for download!
This release brings a handful of minor improvements, and a lot of bug fixes. Additionally, it enables a new virtual texture dataset based on Sentinel-2 data.

I've been working with @plateauastro.bsky.social on a new virtual texture for #GaiaSky which features many urban areas down to a resolution of 10-20 m/px. It is based on Sentinel-2 data and the NASA blue marble imagery. Check out the video 🎞️👇

In the next version, Gaia Sky will pull localized object information from the @wikipedia.org API whenever available. This shortcoming in the internationalization of the app has been mended.

See video below, where the object summary depends on the current locale 👇

#GaiaSky will get a star streaks shader in the next release. This effect elongates stars in the direction of motion to create a sort of Star Trek travel effect. Of course, this can be turned off in the settings.

#GaiaSky 3.6.8 is clearly GPU-bound. This means that the graphics card is the limiting factor in performance.

The footage below is captured with the GTX 1070, which is now almost exactly 9 years old. But the software runs well also on integrated GPUs (laptops mostly), and APUs (Steam Deck).

📢 🚀 #GaiaSky 3.6.8 is out now! A big update packed with improvements:

- Complete UI refresh
- One-click "recommended datasets" for newcomers
- Star/particle rendering upgrades
- Major performance gains across the board
- Tons of fixes, polish, and under-the-hood refactors

📢📢 Today we make available a new Gaia DR3-based catalog: Gaia DR3 Best!

It is a small and compact catalog with only the very best stars in terms of parallax relative error. It contains 646K stars and weighs ~54 MB.

All the info: gaiasky.space/news/2025/ne...

Been doing some UI work in #GaiaSky to clean up the themes and make it possible to generate themes automagically from an accent color. Now we need to decide the default theme. Which one is your favourite? See poll below.

The 8th #Gaia DPAC Consortium meeting starts today. More than a 100 scientists and engineers from all over Europe gather in Cambridge to discuss the road ahead that leads to the 4th Gaia data release, #DR4.

Today, Gaia has been ejected from its Lissajous orbit around L2 into a heliocentric orbit. The spacecraft has ended its sky-scanning phase after more than 10 years, and has been switched off. We'll see it again close to Earth in 2039. Farewell, #Gaia!

There is a new API call in #GaiaSky, goToObjectSmooth(). It uses the transitions API to create a smooth trajectory to an object. Comparison video:

I have been re-working the way speed scaling works in #GaiaSky. The new method takes into account all objects surrounding the camera, additionally to the focus object, and produces smoother trips. No more sudden jumps out of the starting area!

📢 We have a new webiste at gaiasky.space!

Also, if you use the Flatpak, our Flathub app id has changed to space.gaiasky.GaiaSky to enable verification. If you install or update the old app ID, it should prompt you to upgrade to the new one.

We are experimenting with a new website for #GaiaSky that is easier to edit and maintain. Check it out!

Today, coinciding with the end of the sky-scanning phase of Gaia, we publish #GaiaSky 3.6.5. The most noteworthy addition is the introduction of the volume rendering infrastructure.

Nebulae also kind of work now in #GaiaSky VR, but I need to port every single shader manually (sigh). Current progress is 1/8, but they all follow the same structure, so the others should be straightforward...

The aurora now works on #GaiaSky VR as well. Now on to the volumetric nebulae...
