What is pulling on it to make it Asymmetric like that

Likely something that passed nearby and had gravitational pull millions of years ago. It could also be pull from the nearby dwarf galaxies, the Small Magellanic Cloud and the Large Magellanic Cloud.

Wow, thank you. It caught my eye right away and made me wonder what could be twisting it that way. Seems to be equal pull in opposing directions but not in the middle. That is pretty wild how it can be throughout the horizontal plane of all the bars and all bodies in the bars together like that evenly.

I wonder if it is a stationary pull and as the bars rotate by they bend as they go by those spots and then back to flat plane? That would add another whole axis of travel up and back down as it goes by the opposing spots wouldn’t it? An added wave action.

And since it is affecting the outer diameter that wave action would also be moving us up and down aside from just a horizontal rotation plane... Of course it is slow but still an added movement though a Galactic year cycle.

Thank you!

Guess I should have said Spiral Arms not Bars... :)
