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.
sshussain270•4d ago
This is very cool! Is this tracking real time locations?
guillaumec•4d ago
Yes mostly. The comets and satellites data is updated twice a day.
sshussain270•4d ago
Nice! You could add satellites too!
RoTor_Ex•3d ago
Gee... That's fucking insane! I like it!

Btw, how many hours do you have in a day to build a non-commercial beta like this in just a year?! :D

I found several issues: 1. Selecting Voyagers and swam back in time: • The Sun was leaving a strange trace of light while moving backward through space; • When voyagers reached the Earth in 1977, they ricocheted from it and flew back into space; • When I changed the selected target during the time simulation, it stopped and lost its simulation speed 2. I can't move my cursor with arrows or Cmd | Option + <> combinations in the "Ask AI" input field

And a few thoughts from me: • You missed the favicon =) • Behavior, when you first should click on the object and then click "center" to fly to it, is a bit counterintuitive and confusing. I personally expected scroll target changes automatically when I clicked to a different object • What do you think about adding the same scale across the whole Universe (esp. in the local stars group) that the Local Group has with vertical lines from the plane of the ecliptic? • Should you add a few more DSO objects like TON 618 in the "Featured" catalog?

It’d be interesting to hear how you see this evolving and what the original idea was. Are you trying to compete with other universe exploration apps, or build it more like a browser-based atlas of the Universe?

guillaumec•3d ago
Thanks a lot for the feedbacks! I spent quite a lot of time on this yes, though I was already quite familiar with 3d rendering and astronomical computation so it wasn't that hard. In fact the most difficult part was probably to learn WebGPU that I never used before.

For the issues:

1. Yes there are some bugs currently with the temporal anti aliasing. I was a bit aggressive on the effect because without it the Milky Way doesn't look good. I'll try to fix that (ideally it should adjust to the the velocity field).

2. All the time controls is still pretty much untested, I'll see if I can fix that.

3. I'd like to add more scale hints, but it's hard without cluttering the view. I'll see what I can do.

4. Yes at the moment there is only one black hole (sgr A*), I'll add more as soon as I can.

As for how this will evolve, I am not sure yet. I have a basic mobile version prototype working on iOS, so I thought this could turn into a mobile app at some point. No plan for an actual heavy PC app at the moment.

I had to login just to upvote

I thought it was limited to the solar system until I accidentally kept zooming out, and got my mind blown a couple of times. And again when I saw the black hole.

This is ridiculously well made

guillaumec•3d ago
Thanks a lot, really appreciate!

Very awesome. FYI Voyager(1,2) should be oriented with the big antenna dish pointed towards Earth.
jermaustin1•14m ago
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.
