Like others have mentioned, it’s the original Battlestar Galactica. As a product of the late 1970’s its production was steeped in the aesthetics of the era. It sits in this pocket of time between Star Wars IV and V, and featured episodic sci-fi when mainstream television that was dominated by variety shows (e.g. Sonny and Cher, He-Haw). Serious, campy, scmhaltzy, fun, sometimes great, sometimes awful, and apparently too expensive to avoid cancellation, it stands on its own two feet as its own phenomenon while inviting endless comparisons to classic Trek.
It also spawned this Italo-disco track by Giorgio Moroder himself (not on the show, but more of a fan work of sorts): www.youtube.com/watch?v=51bjtPN_VqU
