You've heard of binary star systems, right? It's where there are two stars close to each other, and they both orbit around a common center of mass. Sure, you saw binary stars in the original movie, where Luke Skywalker was on the desert planet Tatooine. Oh wait, that's Star Wars and this is Star Trek. I'm kidding, I know the difference. But binary stars are real.

So … what about an octonary system, one with eight stars, all gravitationally interacting with each other? That's what we get in Star Trek: Picard. In this case it’s actually an artificially created system set up by an alien race long ago as a warning sign for future civilizations—uh, long story. We'll know more after watching the season finale, which comes out today.
