What makes you think no-one had been to Coalsack? Lots of people go there - the guy who went to the opposite side of the galaxy went via Coalsack a long time ago. You don't see many screenshots of it, but it's a common destination from what I've seen when explorers get chatting!In one of my threads, I've described my journey to Coalsack Nebula - a thing that is relatively close to Sol, yet no one has gone there. Maybe because it's not one of those colorful, shiny nebulas, on the contrary - it's name says it allI don't know, but if you look around and check forums, I'm sure you'll find places, even so obvious as the Coalsack Nebula, where no one has gone yet.
