It’s been 26 long years since Star Trek: The Next Generation graced the small screen. But beginning Jan. 23, a new series centered around that show’s captain, Jean-Luc Picard (Patrick Stewart), will “boldly go” to the network’s streaming service, CBS All Access. Star Trek: Picard is about our titular captain’s life many years after his last fateful mission for Starfleet.

But how does Picard fit into the larger Star Trek timeline? The CBS series is set where no Trek has gone before, well past the events of TV’s Star Trek: Voyager and the last film of the Picard era, Star Trek: Nemesis. Many fan favorite characters are expected to return, including Commander William T. Riker (Jonathan Frakes) and Seven-of-Nine (Jeri Ryan).

For Trek nerds out there, this means Picard takes place in the “prime” timeline, which is where each of the television series and the original films live. In 2009, J.J. Abrams rebooted the series with the film Star Trek, creating a new timeline for the already confusing Trek universe. In the film, a bad guy travels back in time and destroys the USS Kelvin, killing Captain Kirk’s father, George Kirk, in the process. All three of J.J. Abrams’ movies take place in this alternate timeline called the “Kelvin Timeline,” after the annihilated ship.

To familiarize yourself with the Trek universe, here are the two timelines:
