If this is an artificial object, it looks mature. It took a while to make
it look like that. If they started expanding at the time they started
engineering it, they would have colonized our local galaxy pocket (it's
merely 600 megalightyears away), including this one. This a) would be
highly visible b) you wouldn't be here if they did that.
Since you can see it, Hoag's object is most likely natural.
