Maybe it’s just a coincidence, but a new series that was just greenlighted and another series that just received a second-season order both have strong connections to the original “Star Trek” TV series.

History announced the orders for both shows this week. The new nonfiction series “The UnXplained” (working title), which was just greenlighted, is hosted and executive produced by William Shatner — Captain Kirk of the original “Star Trek.” Meanwhile, “In Search Of” — a series closely associated with “Star Trek’s” Spock, Leonard Nimoy — received an order for a second season.

Nimoy, who died in 2015, was one of the hosts of the original “In Search Of…” when it aired as a syndicated program back in the late ’70s and early ’80s. History’s new version of the series is hosted and executive produced by Zachary Quinto.

“Both ‘The UnXplained’ and ‘In Search Of’ strive to solve some of the world’s most intriguing mysteries, and it’s this truth seeking that resonates most with our viewers,” said Eli Lehrer, executive VP and head of programming for History. “These shows will offer credible answers to questions about mysterious phenomena, while others will remain unexplained. Who else better to transport audiences through this journey than William and Zachary, whose passion, curiosity and perseverance to present every side of these enigmas beam on screen.”
