While in New York, my mom visited the Hayden Planetarium of the American Museum of Natural History. The Director of the Hayden Planetarium is, of course, astrophysicist Neil deGrasse Tyson. He presented Cosmos: A Spacetime Odyssey on television. He is one of my heroes! She bought a copy of The Pluto Files that was signed by Neil deGrasse Tyson himself!
