When he was nine years old, Neil deGrasse Tyson went on a trip that would change his life. While visiting the Hayden Planetarium at the Museum of Natural History in New York City, he discovered the world of astronomy and felt like the universe was calling to him. He answered that call by diving deep into astronomy courses. After graduating from the Bronx High School of Science, he went on to earn a doctorate in astrophysics and eventually found his way back to the Hayden Planetarium as a staff scientist and, later, as its director.
