Just watched The Farthest, a fantastic in depth account of NASA's Voyager mission. Superb documentary, loved every second of it... not just for the incredible story of the Voyagers that will in all likelihood outlive humanity (and may well be the last record of our existence), but also because of the wonderful directing and music. Just amazing. Thanks, @Bluewolf.
It also made me think that some intelligent inhabitants of a far away galaxy finding the Golden Record and learning about us some millions years into the future would make a great plot for a scifi movie or novel. Maybe I should start working on it
