As the iconic Captain Kirk in the revered “Star Trek” franchise, William Shatner’s character traveled to alien planets, encountered ancient civilizations, and traveled in advanced aerospace vessels, but now Shatner has set his phasers to take aim at real-life unexplained cases of other worlds, and extraterrestrials starting with a two-hour cross-over episode of “Ancient Aliens.”

Shatner, host the History Chanel’s “The UnXplained,”for the first-time ever will join a roundtable discussion on the Feb. 12 episode of “Ancient Aliens” with ancient astronaut theory experts Giorgio Tsoukalos Erich von Däniken, David Childress, William Henry, Linda Moulton Howe and others.
