$\begingroup$ When I looked at this question it had a zero rating, but to me it's the only answer that makes sense. When the question says "star system", I assume aliens can see their planets. Dust clouds are not dense enough to hide all nearby stars. We wouldn't have to wait for the far future, because stars can be "thrown out" of a galaxy just as planets can be expelled from a newly forming solar system. When the aliens invent telescopes to see their planetary neighbors one might look around the rest of the sky for fun and find a nearby galaxy. $\endgroup$
