Neil deGrasse Tyson will be back on the National Geographic Channel now that the network has completed an investigation into accusations that the celebrity astrophysicist engaged in sexual misconduct.

“StarTalk” will return to the air with the remaining 13 episodes in April on National Geographic, and both Fox and National Geographic are committed to finding an air date for “Cosmos.” There will be no further comment.

Nat Geo and Fox chose to investigate the allegations and held off airing episodes of “Cosmos” and “Star Talk” until the investigation was complete. 21st Century Fox is the parent company of the Fox network and has a majority stake in the National Geographic Channel.
