Thank you for posting this, OP.
I certainly did not realize that our Milky Way galaxy was that "dynamic" still.

OP a question about that very interesting pic you've posted. From a victim suffering with 0 knowledge of astronomy.
Why does there seem to be a perimeter where the stars just stop and then beyond that perimeter there is only a blackness ?

I'll throw a guess out there - maybe there's something akin to a galactic "termination shock", like the solar syatem has, but on a larger scale.
