I did some experiments in after effects
with fractal noise and volumetric light effects
just to have an idea , look what can be exploited

Nacer, on the one hand, I see that the animation was created quickly and looks complicated. On the other hand, I can understand what mechanisms here were used without the use of 3D-technologies, only due to 2D-technologies. As far as I understand the ideology of After Effects - in the first place it is a 2D program, in which there are no serious possibilities for working with volumetric light. As imitation of 3D phenomena and processes is an excellent option and can be used for many tasks. However, I would like to get the most reliable image, with a real play of light and shadow on the volumes, taking into account the re-reflections, changing the lighting passing through the thickness of particles and so on. I still do not see an opportunity to achieve my goals with After Effects, because I do not have a goal to get a video, but I need a static and quite realistic picture.

Full HD
...
i can make it 4K or 8K as i want, of couse with AE in just few minutes.
The nebula is not as chaotic and complex as you pictured. It contains not only radiating components, but also absorbing, reflecting, and even re-re-re-reflecting (astronomers are now developing a technology that will allow to reconstruct the events that took place 10, 100, 1000... of years along the paths of light rays that are reflected in different parts of the nebula backward). The nebula can be seen as a landscape in 3D. There is no bottom or top, but there is a land, sky, trees and Sun. Many Suns! Look, what a beauty:
Carina nebula:
[attachimg=1]
NGC 6357:
[attachimg=2]
Orion nebula:
[attachimg=3]
After effects can not construct the nebula from its components, keep the dependencies between them when switching the seeds and rotate the camera 180 degrees and look from the back while preserving the entire structure. This is the territory of 3D-graphics.
But After Effects is faster and more artistic than TG can do animation of some processes, and also add some good effects. With this I will not argue. But in my opinion, it is better to consider it as an addition to TG, and not as an alternative.
