This is really interesting! (least to me)
I divided the original 2D-Veil image to the layers by the content.
(parts of nebula, stars by size and the background)
Each layer was then projected to the 3D-surface.
The main principle is about the same as in Stereo Pair images.
In this tecnique the data is really in 3D-format though.
I think this video tels a lot about nature of this object as a 3D bubble, leftovers from
massive explosion, Supernova.
NOTE. This is not a accurate model, it's more like an educated guess about appearance.
The original 2D-image, with imaging details, can be found here:

3d-stero pair image is here:

and
Stero pair animation! of exploding star is here:

There is couple of hick-ups in the video, since I'm very new with any animation techniques, yet.
Video compression kils the movie here. Original
HD-quality movie has stunning details and about zilion and half more stars.
