Thanks neufer

One thing I've always wondered is how the stars in these dense clusters keep from combining and creating one gigantic star, since they are so close to each other. It se...

Ok, now I see your diagram and it all makes perfect sense. Because of the distances involved, an M96 oberver will see the background galaxy at virtually the same size we do, observing from the Milky Way. Thanks.

Your question doesn't make any sense to me, so maybe I didn't explain myself clearly. I'll try again. Thanks for your patience: M96 is 38M light-years from us, yet we cannot go out and see it in the night sky. The background galaxy that lies beyond M96 in today's APOD pic is supposedly 150M miles fr...
