I know. I myself don't want to believe in it.

Unlikely, but unable to be ruled out.

However, it isn't the black hole that bothers me.
It is that at that size, it has to be decaying.
Even black holes leak, or so the theories go, and this one has gone billions of years with nothing to eat.
What happens when it loses enough mass to go from a singularity to a neutron star?
Could that expansion be fast enough to blow off chunks of still expanding matter?
What about the shockwave?

Since development of the new version is already starting, I guess it's already time to make my own suggestions about what I would like to see in the next release(s). Here are five of them.

1. Not sure if you are interested in adding a few new nebulae, or if these fit to your standards, but I could suggest the following addons by jll, that apparently were only published on this forum. They are as following:
- Barnard's Loop: viewtopic.php?p=76259#p76259
- M27 (Dumbbell Nebula): viewtopic.php?p=64797#p64797
- M1 (Crab Nebula): viewtopic.php?p=64953#p64953
- MyCn18 (Hourglass Nebula): viewtopic.php?p=51909#p51909
Also, this addon by Edasich contains some real nebulae: http://celestiamotherlode.net/catalog/show_addon_details.php?addon_id=1495

2. Perhaps you should add LukeCEL's jsdc.stc (viewtopic.php?p=141568#p141568) and cross index files (viewtopic.php?p=142221#p142221)

3. Texture maps for comets imaged by spacecraft. Some of them are available through the 3D Asteroid Catalogue.

4. I suggest including a shape model for 2008 TC3 (https://astro.troja.mff.cuni.cz/projects/asteroids3D/web.php?page=db_tumblers) and updating the models of Thebe and Kleopatra with the ones at the asteroid catalogue.

5. Lastly but not least, update the location files, especially for asteroids. I know this might take time and be not so easy.

Feel free to consider my suggestions as you want, but before everything, thanks in advance for your attention! :hi:

Hi pedro_jg, thanks for providing the links to the nebulae! I thought I had found all the nebulae add-ons on the Internet, but I guess I hadn't.

Out of the ones by jll, I think Barnard's Loop is the best-looking. Sure, it doesn't look right when viewed from the side, but the hazy look is well-depicted. However, I think all of them need to be realigned. When I visited them in Celestia, they weren't oriented the right way.

It might be possible to recreate MyCn 18 out of overlapping sprites.

Best,
Luke

Don't forget the Carina Nebula, The Veil Nebula/Cygnus Loop, the Tarantula Nebula, the Running Chicken Nebula, some additional planetary nebulae, and HH objects

Additional galaxies could be considered, however, we must also suggest making more accurate galaxy models, since some of them don't do their respective galaxies justice.

I appeal to everyone. I am certainly pleased that you want to see more interesting objects in Origin, but please restrain your appetites this time. The tenth release is assigned concrete global and very important tasks that require urgent execution. Maybe I’ll do some of the above, but I can’t promise.

It's alright. You can do the rest in the 11th release, or if ever Celestia Origin will eventually be released for Celestia 1.7.0 and made compatible with it.

The problem is that we don't have suitable addons for those objects, as far as I know.

Okay, not the least problem with that :wink:. I perfectly understand that you have your own priorities. I wish that all goes well with the development, though :smile:!

This is not related to the topic but today is the anniversary of Sputnik 1's launch. So, Happy Sputnik Day everyone! :smile:

Sorry, but this request is rejected. It turned out that these topo do not coincide with the current 3D-models (it is the result of differences between data from Voyagers and Cassini). Already added maps of Janus and Epimetheus will be deleted. :sad:

ah. no problem, yeah they were from voyager data, I don't know how accurate they are with Cassini, i know that proteus is probably completely misaligned.

Now we need a way to highlight moons in a grouping.

Since the new moons are part of three different groupings, it would be nice to be able to show those.

Or mark things things that are prograde vs retrograde, just for fun.
