Fox, National Geographic, the Museum of Natural History, and the producers of Cosmos announced investigations, which Tyson said that he welcomed. The National Geographic Channel announced on January 3, 2019, that they were putting further episodes of StarTalk on hiatus so as "to allow the investigation to occur unimpeded". The premiere of Cosmos: Possible Worlds, initially scheduled for March 3, 2019, was also delayed while the investigation continued. On March 15, 2019, both National Geographic and Fox announced, "The investigation is complete, and we are moving forward with both StarTalk and Cosmos," and that: "There will be no further comment." The networks affirmed that both StarTalk and Cosmos would resume, but that no date had been set. In July, the American Museum of Natural History said that Neil deGrasse Tyson would keep his job as director of the Hayden Planetarium.
