Renowned astrophysicist Neil deGrasse Tyson has responded to allegations of sexual misconduct levelled against him.
Tyson said he will cooperate fully with an "impartial investigation" into allegations made by two different women.
Patheos.com recently published accounts from two women who say that Tyson behaved in a sexually inappropriate manner towards them.
Tyson was host of "Cosmos: Possible Worlds" on Fox in 2014 and a new edition of the series was to air on National Geographic next year.
In a lengthy Facebook post, Tyson denied an accusation that he groped a woman and he denied that he made sexual advances towards a production assistant when he invited her to share wine and cheese at his home.
He apologized for making the production assistant feel uncomfortable.
Fox and National Geographic Networks have said they will conduct a thorough investigation.
