As a lifelong fan of astrophysics, and having contemplated the vastness of space quite a lot, I think it's entirely unlikely that that is a galaxy at the end of ESB. I understand that Star Wars rarely, if ever, obeys the laws of physics, so this is just for the sake of providing some insight and I think adywan is thinking along the same lines, so maybe this avoids him having to elaborate.

I've often felt that only the worst space fiction treats galaxies like countries or planets one can easily hop between. For all intents and purposes, this galaxy we live in IS the universe. Even after we achieve faster-than-light travel, we will likely never leave our galaxy. Even at 100 times the speed of light, it would take 1,000 years to cross the Milky Way. Talking about the distance between galaxies, even at 1 million times the speed of light, it would take 2 full year to get to the nearest galaxy.

It is simply unlikely, even with the most advanced technology one can dream of, even with wormholes, that lifeforms are capable of leaving their own galaxy.

Damn!!
