Neil deGrasse Tyson is an astrophysicist and science communicator. He is also an author. Have you ever heard of him?
Yes I have, he also put out a book and has a TV show. Have you seen it?
I have not, but will check them out. He's also the Frederick P Rose Director of the Hayden Planetarium in New York.
Oh wow, I didn't know that. What is the Frederick P Rose Director?
Frederick P Rose was was an American real estate developer and philanthropist. The center is named for him.
That's interesting, I didn't know that. Have you ever been to a Planetarium?
I haven't, but spent some time with an astronomer once. Tyson actually became interested in astronomy after visiting the Hayden Planetarium, where he is now Director.
It's funny how he came full circle. I've always wanted to visit a planetarium. 
Me too. Having visited one as a child, Tyson then joined that very Planetarium as a staff scientist. Amazing stuff!
