He’s referring to the fact that you can see the Milky Way from the surface of the Ark, which alerts the player to the fact that they have managed to travel outside the galaxy. (Here’s a picture of what it looks like in the skybox:

That’s pretty cool. I never noticed it before. Thanks for the info and the pic…
