绘本简介

As a young boy growing up in New York City, Neil deGrasse Tyson was fascinated by the sky above. Tyson followed his interest in space to become an icon in the field of astrophysics. As the director of the Hayden Planetarium, Tyson became well known for his role in the debate surrounding Pluto's status as a dwarf planet. In the tradition of Carl Sagan, Tyson educates the public as the host of the History Channel's television series Cosmos: A Spacetime Odyssey. Tyson's love of science and learning serves as a stellar example for kids and adults alike.
