#GaiaDR4 is coming! Mark your calendars: 𝐖𝐞𝐝𝐧𝐞𝐬𝐝𝐚𝐲, 𝟐 𝐃𝐞𝐜𝐞𝐦𝐛𝐞𝐫 𝟐𝟎𝟐𝟔. This release contains data from the first 5.5 years of the mission. The data volume will be 50x larger than DR3! www.cosmos.esa.int/web/gaia/dat...

🍎 To all macOS users: Gaia Sky can now be installed via brew! Learn more here: gaia.ari.uni-heidelberg.de/gaiasky/docs...

Loading datasets on-the-fly in #GaiaSky just got easier: We've added a new "Installed Datasets" tab to the load dialog, allowing you to quickly jump into your library without browsing folders. The classic file picker is still there for your custom .vot, .csv, and .fits files. Watch below! 🎬

Anyone know where I can find an open&free Orion service module 3D model? I looked at the NASA and ESA websites, but there's only a rough model for 3D printing. All models in sketchfab&co seem to be paid.

Here is an animation of the Artemis-II mission and the Lunar flyby. #Artemis #Artemis2 #NASA #ESA #GaiaSky @exploration.esa.int @esa.int

Release day: #GaiaSky 3.7.2 is out! 📢📢📢 This one comes with many new features and bug fixes, as usual. See the release notes here: gaiasky.space/news/2026/ga...

I liked this #ArtemisII picture of the Moon so much, that I tried to recreate it in #GaiaSky. Left is the real picture, right is Gaia Sky.

✅ #Artemis II update: 'Earthset', 6 April 2026, and 'totality', 7 April, seen from lunar orbit, the Moon eclipses the Sun, a view few humans have ever witnessed (pics: NASA) 🔗 www.nasa.gov/gallery/jour... @exploration.esa.int l

😮 Awesome views from Day 2 of #Artemis II this morning. @exploration.esa.int @esaearth.esa.int

You’re gonna want to turn the sound on for this one 🔊 Europe’s contribution to #Artemis is powerful, precise, and built for deep space. With the European Service Module powering Orion, Europe isn’t just watching history unfold. It’s creating it. Delivered by ESA, built by Europeans. L-12 🚀

🚀🌕 Artemis II Countdown läuft! Voraussichtlicher Start ist am 2. April 2026 um 00:24 Uhr MESZ. Erstmals seit fast 55 Jahren fliegen Menschen wieder Richtung Mond. Den Start könnt ihr via Livestream verfolgen: www.youtube.com/watch?v=JIua... (1/4)

Early this morning, at 00:35 CEST 2 April, NASA's SLS rocket lifted off from the Kennedy Space Center. At the heart of the Artemis II mission is ESA's European Service Module, which powers, propels and sustains the Orion spacecraft and its crew on their journey around the Moon and back to Earth.

A new Gaia Sky release is in the horizon. What are the new featrues? Here is a writeup detailing them. 👇 gaiasky.space/news/2026/3....

Been working on a dataset to add some detail to the rings of Saturn in the form of particles. I'm quite happy with the result, especially the performance. The video shows 1.5 million rock/dust particles. Transitions to/from the ring model are quite seamless. #GaiaSky #Saturn #SolarSystem #Astronomy

I've been plyaing around with the keyframes system in #GaiaSky and the OptFlowCam export method. After some bug-fixing, it produces very good results. It works best in a "points of interest" workflow. The following video is exported from only 25 keyframes.

Yet another video of the asteroid belt using Gaia DR3 data with the new shading. #GaiaSky #Gaia #GaiaDR3 #Space #Asteroids #AsteroidBelt #Astronomy

Do you have red-cyan anaglyph glasses? Try this video below for an amazing 3D effect on the asteroids in Gaia DR3.

Asteroids, other SSOs, and particle sets in general will get a much needed improvement in visual fidelity in #GaiaSky 3.7.2. We can now shade them (kind of) realistically while maintaining the high frame rate. In the video, we show the ~150.000 asteroids in Gaia DR3.

What will Earth look like when Artemis II goes to the Moon? Which "phase"? Monday night at 8:00 PM ET, I'm doing a live stream showing you a cool free app called Gaia Sky. I'll show you the possible ways the Earth and the Moon will appear. @gaiasky.bsky.social www.youtube.com/watch?v=9SgB...

Testing #GaiaSky VR with the Valve Index and an RTX 5080 (laptop). Performance is very, very good!

Working with a contributor on the Simplified Chinese translation of #GaiaSky. This requires some re-engineering in the UI system, but we're getting there.

I just got a new laptop for our VR demonstrations with an RTX 5080 16GB. With base #GaiaSky and default datasets, it's getting over 700 FPS. Let's see how it does with VR😅

#GaiaSky 3.7.1 is now available! 📢📢📢 This release comes with many new features and bug fixes. Check it out 👇 gaiasky.space/news/2026/ga...

📖 We have updated the #GaiaSky documentation with a new theme and we've done a little bit of restructuring. It should flow better and look cleaner now. Give it a try! gaiasky.space

Today is testing day, so it's time to dust off the Valve Index and see how much VR on Linux has improved since the last time I tried (it was underwhelming). With the Steam Frame on the horizon, I'm kind of excited to see the progress. #GaiaSky #GaiaSkyVR #VR #valvesoftware #ValveIndex

#GaiaSky will get an interactive UI accent color in the next version, dropping the static UI themes system. 👀

The provisional release notes for Gaia Sky 3.7.1 (to be released very soon) are kind of massive: gist.github.com/langurmonkey... #GaiaSky #releasenotes

🚀 Gaia Sky server is BACK! After a few months of downtime, our main server is once again accessible from the outside. You can now access installers, datasets, and documentation. Thank you for your patience during the downtime. More info: gaiasky.space/news/2026/se... #GaiaSky #Astronomy #SciComm

🚀 To all Gaia Sky users: Having trouble accessing the servers? Here's a workaround to get Gaia Sky running with the base data package during the current downtime. Check out the full guide: gaiasky.space/news/2025/wo... #GaiaSky #ServerDowntime #Astronomy #SpaceVisualization #TechTips

I just saw this on HackerNews and it is so cool and impressive. Gaia Sky uses SDFs for some nebulae, but this work brings the technique to a whole new level. Well done!

I just released my video about the engine (and game) I've been working on. The engine is based on dynamic SDFs, and the video describes how it works and what it makes possible. Link in the reply! This is my first YouTube video and it took forever - please repost!

🚨 Our server remains completely blocked from external access due to the university IT department's ongoing network restrictions. This situation is extremely disappointing for our team and community.

Here are some interesting screenshots of our usage and download statistics. Note the sharp decline at the time where the server downtime starts. #GaiaSky #stats #serverdowntime

Service update: Our server is still down due to uni-wide security measures. Hoping for a fix soon... I was planning a pre-Christmas release, but that's off the table for now. Full details: gaiasky.space/news/2025/se...

I made Andomeda with the new procedural galaxy generator in #GaiaSky 🌠

Even though macOS does not support OpenGL 4.3, the new procedural galaxy generation in #GaiaSky will also work on these systems via a fallback option to CPU processing. It is (just a bit) slower than the GPU version, but it works.

🚧 Our server hosting Gaia Sky builds, datasets, and documentation is currently inaccessible due to precautionary measures by the university's IT team. We apologize for the inconvenience and will provide updates as soon as we have more info. www.urz.uni-heidelberg.de/en/precautio....

I've been working on the procedural generation of galaxies in #GaiaSky for a while now. The system is already able to generate different morphologies, but I'm still tuning it. Below is an example of 3 random galaxies for every Hubble sequence morphology. Full resolution: i.postimg.cc/h4sNWVFH/hub...

The compute shader that generates galaxies gets more and more features. We can now design pretty cool shapes interactively.

The new Steam Frame looks very promising for demos. If the graphics chip in the headset is powerful enough, it could run #GaiaSkyVR without the need of a PC. It already runs well on the Steam Deck, so there is hope. We'll need to wait for the specs to come out. @steampowered.com #SteamFrame

New feature for #GaiaSky VR: Demo Mode. It simplifies the control scheme for first-time VR users, perfect for public demos. Read more: gaiasky.space/news/2025/vr...

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'.

#GaiaSky 3.7.0 is out! If you are on macOS Tahoe, you need to update, as this fixes a bug that prevents the app from starting. But there is much more to this release! Many new features and QoL improvements: gaiasky.space/news/2025/ga...

There's only ~30 satellites needed to make GPS work around the world. I wanted to show this to students, and I'm super pumped how this turned out! Working with @gaiasky.bsky.social, we grab the orbital data of each satellite and show them circling around Earth They look like electrons in an atom

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.
