@mcnees Then again, I once read an estimate that, given what (we think) we know about the presence of dust in the interstellar medium, the Voyagers would be substantially destroyed through dust ablation in something like 1 billion years (roughly 4 galactic rotations).

@mcnees I always wondered about the tendency of stars to drift apart as we all orbit the Milky Way. Would the map still be all that valid after, say, one galactic rotation after launch?

Congratulations to the Arkaroola Wilderness Sanctuary on being named the first International Dark Sky Sanctuary in South #Australia! 🇦🇺
