Biografia e Jornada do Autor
Carl Sagan was born in Brooklyn in 1934 and grew up in a working-class Jewish family that encouraged curiosity, reading, and faith in public education. Childhood visits to the 1939 New York World’s Fair and early encounters with astronomy helped shape his sense that science could enlarge ordinary life. He studied at the University of Chicago, earning degrees in physics, astronomy, and astrophysics, and developed the broad intellectual style that later defined his public voice. After research and teaching posts at Harvard and elsewhere, he joined Cornell University, where he became a professor and one of the most recognizable scientific figures of the twentieth century.
