His interest in science began in his childhood and was nurtured with the support of his family. After graduating from Rahway High School in 1951, he pursued studies in physics, astronomy, and astrophysics at the University of Chicago. In 1960, he completed his doctoral dissertation on "Jovian Atmospheres."

Scientific Contributions and Research

Sagan gained significant recognition in the scientific community for his research on planetary atmospheres. He contributed to NASA’s Mariner, Viking, Voyager, and Galileo missions. He was one of the scientists who identified that the high temperatures on Venus were caused by the greenhouse effect. Additionally, he conducted studies on the possibility of life on Mars and the chemical processes occurring on Titan, Saturn’s moon.

He played a leading role in the preparation of the Voyager Golden Records, which carried sounds, images, and music from humanity into space. He also supported the search for extraterrestrial life and was actively involved in the SETI (Search for Extraterrestrial Intelligence) project.

Scientific Publications and Contributions to Popular Science

To bring science to a wider audience, Sagan authored numerous books and produced documentaries. His 1980 television series Cosmos: A Personal Voyage significantly contributed to the popularization of science. His science fiction novel Contact was adapted into a film in 1997, reaching a broad audience.

Some of his most notable books include:
