Neil deGrasse Tyson

As a kid, Neil Tyson first glimpsed the magic of the Universe in the Hayden Planetarium at the American Museum of Natural History, and was hooked. Today, he is the Director of the Hayden Planetarium. He continues to research galaxies, works with a team to create new space shows, but most of all, loves explaining how the Universe works.
