Neil deGrasse Tyson's series on the National Geographic Channel will not see the light of day pending results of a sexual misconduct investigation against him.

The network temporarily pulled "StarTalk With Neil deGrasse Tyson" from the air just three episodes into Season 5, which premiered Nov. 12, after several allegations surfaced. The show features the famed astrophysicist talking about science with a different special guest in each episode, including Anthony Bourdain on the season premiere.

"In order to allow the investigation to occur unimpeded we chose to hold new episodes of 'StarTalk' until it is complete," Nat Geo said in a statement obtained by Variety and The Hollywood Reporter. "We expect that to happen in the next few weeks, at which time we’ll make a final decision."

USA TODAY reached out to the network for comment.

New allegations against Tyson surfaced late November after two women accused him of inappropriate sexual behavior in a story posted on Patheos.com.

Ashley Watson, his former assistant on "Cosmos," says she quit her job after he made inappropriate sexual advances one night at his apartment after work, while Dr. Katelyn N. Allers, a Bucknell University professor, says she was "felt up" by Tyson at an American Astronomical Society convention in 2009.

In December, another woman came forward in a Buzzfeed News story that claims Tyson drunkenly propositioned her at a 2010 staff holiday party at the American Museum of Natural History in New York, where he serves as director of the Hayden Planetarium.

These three allegations followed Tchiya Amet, who alleged Tyson drugged and raped her while they were grad students in the astrophysics program at the University of Texas in the 1980s. She went public with her story in 2014.

Tyson addressed the allegations against him in a lengthy Facebook post in December, offering his own account of events regarding Watson, Allers and Amet. He ended his statement by welcoming an investigation into his actions.

"In any claim, evidence matters. Evidence always matters," he wrote in the post. "But what happens when it’s just one person’s word against another’s, and the stories don’t agree? That’s when people tend to pass judgment on who is more credible than whom. And that’s when an impartial investigation can best serve the truth – and would have my full cooperation to do so."
