Neil DeGrasse Tyson, an astrophysicist and series host, takes viewers on what can literally be called a cosmic journey, as science probes the meaning, and existence, of the universe. The four two-hour programs are titled "Earth Is Born," "How Life Began," "Where Are the Aliens?" and "Back to the Beginning."
