Celestia Worldbuilding Project

Greetings to all Celestians!

This project has been revealed to us before but it was deemed not capable of being fulfilled because of a lot of problems that members have encountered. So, we have deliberated on the future of the project, until we have settled on it. So now, allow me to unveil to you: The new Celestia Worldbuilding Project!

This new version of the project will not anymore be based on an entirely fictional galaxy in a void universe but rather, on a real object: The Triangulum Galaxy, or Messier 33, the third-largest galaxy in the Local Group, and while it does not have a lot of stars, it is rich in nebulae, particularly H II regions, and as such, creativity for objects other than stars and planets is welcome as well.

The website for the project can be found here: https://sites.google.com/view/celestiaworldbuildingproject/home
Credits to fyr02 for making the website.
There is now a wiki as well, which can be found here: https://celwp.miraheze.org/wiki/Main_Page

And to kick off this new project, allow me to "cut the ribbon" by making and show the very first addon to be made for this project. Presenting to you: The Triangulum Galaxy Central Black Hole!

The fixes are already mentioned in my addon topic. But for easier access, let me repost it here as well:

Fixes: Fixed the Inclination and ArgOfPericenter of the Black Hole and its component disks. It should now be on the same plane as the Triangulum Galaxy itself. I also reduced the ridiculously fast orbital periods of the disk(Far too ridiculous for even the fastest spinning black holes, that is), especially those farther away from it. They should now be slower. I also reduced the AbsMag of the black hole. It was an artifact that came over when I made a copy of my 3C 273 addon and remade it into the M33 addon you see today

Credits to SevenSpheres, pedro_jg, LukeCEL anf fyr02 for helping me point out those problems with the addon. Again, if there are more problems, feel free to let me know

With all the strife caused by the CelWP both here and on Discord (and I apologize for being a major part of those arguments), I'm really more interested in seeing the stellar distributions for galaxies and the NGC 604 sprite model that will be coming...

Anyway, on to the worldbuilding!

(Also, the black hole isn't black in Lafuente's screenshots due to this bug in Celestia 1.7.0 that I would really like to see fixed.)

Well, as much as we both hate it, arguments are a fact of life. They may happen again but the best we can do is learn the lessons and forgive and forget afterwards. This will also ensure that the bond will be stronger than ever. So yes, let us enjoy the worldbuilding

CelWP Release 1
March 28th 2020

3 systems were added with a total of 3 planets.

[SevenSpheres]

Here's my sort-of contribution to the CelWP: the real high-mass X-ray binary system M33 X-7. Download here: M33 X-7.zip (I've also added that link to the first post of my addons thread). If you have Luke's Triangulum Galaxy stc file, make sure it's loaded before this addon (for instance, I have all Luke's extragalactic stars in a folder called "Extragalactic stars", which is loaded before "M33 X-7").

Maybe some sophonts who live nearby can explore this system.

Added after 1 hour 52 minutes:
For some reason, Lafuente_Astronomy has just deleted the first four posts of this thread with absolutely no prior discussion, so the beginning of CelWP is no longer documented and the original addon files are no longer available. These posts should not have been deleted as they were not spam. This may warrant the removal of Lafuente's Moderator role. Eh, whatever

Added after 1 minute 23 seconds:
Here are the two old addon packs made by me: CELcollab Base Pack.zip; CELcollab - Oculus.zip

News for those who don't know, I'm now a part of this project! My CelWP designation will be "PK," and I'm currently working on my first star system!

Hello, I have two questions about these addons.

1. Are the releases cumulative? That is, the last one also contains all the previous ones? Or do you have to download each one and install them all?

2. On the other hand. Is it compatible with the Celestia Origin package?
Can they be installed, copying the addon folder to the extras folder simply or do you have to make an adjustment in a file so that everything works correctly?

Thank you

[Gurren Lagann]

1. Due to weak bandwidth still existing, the releases arent cumulative. You still have to download the releases one by one (unless i compile everything into a single file).

2. I'm not a common CO user, but its probs compatible with it.

Yes, since all the systems in CelWP are entirely fictional, they're all compatible with Celestia Origin. They can be installed by just putting the addon folder in extras. The one exception is my M33 X-7 addon, which is a real system and needs to be loaded after CO's folder "stars_outside_the_milky_way".

For anyone who doesn't know - I have also joined the project! I have begun work on the Verai System, a binary star consisting of a B-type star and an late K-type star.

Verai A, the B-type star

I've also been contributing to release 6 and now release 7. I will be making:

A stellar association (coupled with a supernova remnant)
A small quasar
Some things in the magellanic stream
And a quadruple star system, among other things

some screenshots:

[Trolligi 112477]

I am deliberately concealing most of the stuff I've made. Should I reveal more?

Added after 10 minutes 11 seconds:
I'll reveal a little more.

A star system very similar to HM Cancri.

A purple supernova remnant nebula which is the location of the stellar association I mentioned earlier.

The neutron star remnant of the progenitor of that nebula.

Remastered the disk (It's not smaller)
