Astrophysicist Neil deGrasse Tyson will return to the air on two TV shows that had been put on hold for a sexual misconduct investigation. The National Geographic Channel said in a statement Friday that Tyson’s StarTalk will return to the air in April with the 13 episodes that remain in the season. The statement says Tyson’s other show, Cosmos, will return on National Geographic TV and Fox at a date to be determined. Late last November, National Geographic Networks and Fox said they would examine reports that Tyson behaved in a sexually inappropriate manner toward two women. Friday’s statement did not address the complaints or investigation. Tyson hasn’t yet issued a statement on the news, however, in December he had denied the allegations and welcomed the investigation.
