The failure of "Star Trek: Nemesis" in 2002 not only ended the "Star Trek: The Next Generation" series of movies, but also stopped the progress of the saga that explored the real world of the late 24th century for many years. Star Trek: Nemesis took place in 2379, and the next major update came in 2009's Star Trek movie directed by J.J. Abrams reveals that a supernova destroyed Romulus in 2387.

The Romulan Supernova Changed Star Trek After Nemesis

Literally, the most cataclysmic event to occur after Star Trek: Nemesis was the Romulan supernova in 2387, which formed throughout the 2380s. Supernova was invented by J.J. Abrams' Star Trek 2009 was the reason Ambassador Spock (Leonard Nimoy) and Nero (Eric Bana) traveled to the 23rd century, and it was this plot device that made Abrams Ramsay's alternate Kelvin timeline setup for his film. The Star Trek franchise didn't touch on the Romulan supernova, or its offshoots, until Season 1 of Star Trek: Picard wove it into the backstory and made it an integral part of Jean-Luc Picard's present day.
Romulan supernova changed the face of the Milky Way. The Romulan Star Empire was reduced to a shell, its people displaced throughout the Beta Quadrant. Admiral Picard withdrew from Starfleet after the United Planetary Federation abandoned its mission to save the Romulans following the Martian raid in 2285. However, by the 32nd century of Star Trek: Discovery, Romulans and Kvatmirat had resettled Vulcan, and the shared planet was renamed Ni'Var. After the Martian attack, The Federation also banned compositing and droids from 2385-2399 until the end of Star Trek: Picard season 1 changed that ruling.
What Else Happened In Star Trek's Post-Nemesis Timeline

The second half of Star Trek: The Prodigy Season 1, which takes place in 2384, shows the Federation and the Romulans signing a peace treaty related to Admiral Picard's rescue mission. Additionally, Captain Chakotay (Robert Beltran) initiated the USS Protostar's mission to return to the Delta Quadrant in 2383, but the ship got stuck in a time anomaly and appeared over Solum 50 years later in the 2430s. Chakotay was captured by Vau'Nakat, but he managed to send the Protostar back to the 24th century in an effort to keep the ship and the weapon Vau'Nakat installed on it called the Living Construct away from Starfleet.
The post-Star Trek: Nemesis timeline is now the present of Star Trek: Lower Decks and Star Trek: The Prodigy, with Romulan Supernova and the backstory of Star Trek: Picard Season 1 taking place. It's an exciting time for Star Trek, one that continues what Star Trek: The Next Generation began while also setting the stage for Star Trek: Picard Season 2 in the 25th century. Season 3 of Star Trek: Picard will continue the post-Star Trek timeline and reunite the cast of Star Trek: The Next Generation for the first time since Star Trek: Nemesis Offers the worthy ending that the last TNG movie denied them.
