Galaxium can't run in this browser Galaxium uses WebGPU, a recent browser technology that isn't available or enabled here. It works in up-to-date versions of Chrome, Edge, Safari (macOS 26+) and Firefox, on a computer with hardware graphics.

In the meantime, you can explore the night sky at stellarium-web.org — it runs in any browser.

You borked it.

I think your comment could be more helpful--"You borked it" doesn't describe the problem or what you're expecting to be different.

Wow! I'm utterly speechless. I love space "browsers" - I lose myself in them, just clicking through all the entities. Also TIL that there are satellite galaxies, and I've never noticed those on other toys/tools like this. I always though Andromeda was the closest galaxy, but it is FAR away compared to `Sgr dSph` which is within 50kly from the center of the Milky Way.

Same here! I can't believe I never knew of the existence of satellite galaxies until now.

Super cool project! These kinds of viewers seem to pop up every few days, but this one is the best one so far. For feedback, I found it a bit odd that when selecting Sombrero Galaxy for example it zooms to the black hole M104 at the center of it, and actually viewing the entire galaxy then requires several mouse wheel spins :) Otherwise, great stuff.

Hello, I am the creator and maintainer of Stellarium Mobile. I have been working in my free time for about a year on this new project Galaxium, that is more about traveling in the universe rather than looking at the sky from Earth. It is still experimental, and at the moment I am not sure what it will become. Feedback is welcome.

It feels like an improved version of Celestia on the web, which I've wanted for a long time. The rendering is awesome! I like the motion blur on the stars, but it increases the brightness of each star. It would look more consistent if the brightness of a star was constant regardless of motion. I guess the brightness increase makes things look cooler when you're warping through space but it's distracting when orbiting…

Hi there, I see you mention Celestia. I’ve never used it myself but have looked at screenshots and read about it.

I built a WebGL viewer for our local solar system only[0]. If you happen to have the time to give any feedback I would sincerely appreciate it - you seem very knowledgeable about this.

EDIT: With apologies to OP, I don’t want to hijack your post.

I’m currently traveling without a laptop and can’t view your site on mobile - I would love to check it out and share my thoughts and trade experiences about building these space viewers once I have a laptop again in a couple days.
