My poor mushy brain cannot comprehend stars moving like giant comets, in fact some of these have sub 20 year orbits by the looks of it which i doubt too many comets have (as short period comets have short periods of life). I doubt we will ever exhaust the skies of things to discover and thats without even setting our foot there.
