He was a distinguished astronomer, cosmologist, planetary scientist, astrobiologist, astrophysicist, and science writer, best known for his research work on extraterrestrial life. Carl Sagan was also the first person to invent physical messages that could be comprehensible to extraterrestrial intelligence.
In addition to that, Sagan devised and proved his theory on the production of amino acids, where he showed that with the help of radiation, basic chemicals could produce this element. Also, Carl Sagan was the first person to point out that Venus's high surface temperatures resulted from the greenhouse effect. Carl stated that the greenhouse effect might change the climate system of our planet and might turn it into an inhabitable place similar to Venus.
After graduating from high school, Carl Sagan went to the University of Chicago. Here, he completed his bachelor's degree and master's degree in physics and later earned his doctorate also. Subsequently, he joined Harvard University as an assistant professor and later transferred to Cornell University, where he spent the majority of his career. Sagan remained extremely prolific while teaching at Cornell. He published over 600 papers and worked on over 20 books both as an author and co-author. Some of his best books are 'Pale Blue Dot', 'Broca's Brian', and 'The Dragons Of Eden'. Apart from that, he is also the co-writer of 'Cosmos: A Personal Voyage', an award-winning television show from the '80s. Carl Sagan began his career as an assistant professor and went on to become one of the greatest astronomers of his time.
Let's explore the biography of this famous American astronomer and find out more about his childhood, education, best works, achievements, and net worth. So, sit tight and enjoy an informative and entertaining article on Carl Sagan.

Childhood And Education

Carl Sagan was born Carl Edward Sagan in Brooklyn, New York, in 1934, to Samuel Sagan and Rachel Molly Gruber. His father was an immigrant from Ukraine who worked as a theater usher in New York, and his mother Rachel Molly Sagan was a homemaker.
Carl belonged grew up with his sister Carol Sagan. From the remarks of his biographer, Keay Davidson, it is found that Carl's mother was also an ambitious woman. However, her prospects and her wish to achieve something in life remained dumped under the heavy burden of poverty, religious ethnicity, and social status as a woman.
Carl Sagan became interested in science at an early age. The astronomer once said that his visit to the New York World's Fair in 1939 (when he was just four years old) was the turning point of his life. At this fair, the four years old Sagan was dazzled by the technologies that he saw in various exhibitions. The following year, Sagan's mother got him a membership in a public library, where he visited regularly and read books about nature and stars.
Sagan's inquisitiveness towards science and nature was remarkably handled and nurtured by his parents, who used to buy him several reading materials and chemistry sets. Another influence came from science fiction writers like Edgar Rice Burroughs and H. G. Wells, whose writings made Carl Sagan more interested in space and extraterrestrial life.
Sagan's high-school education began at David A. Body Junior High School. Later, the family moved to Rahway, a semi-industrial town in New Jersey, and Carl enrolled at Rahway High School. In 1951, he graduated and went to the University of Chicago. During his undergraduate program, Carl Sagan worked under geneticist H. J. Muller and chemist Harold Urey.
Carl Sagan earned his B.A. degree in 1954, his B.S. (physics) in 1955, and his M.S. (physics) in 1956. Finally, he completed his doctoral thesis, 'Physical Studies Of Planets', in 1960 and submitted it to the Astronomy and Astrophysics Department.
