Carl Sagan, in full Carl Edward Sagan, (born November 9, 1934, Brooklyn, New York, U.S.—died December 20, 1996, Seattle, Washington), American astronomer and science writer. A popular and influential figure in the United States, he was controversial in scientific, political, and religious circles for his views on extraterrestrial intelligence, nuclear weapons, and religion. Sagan wrote the article “life” for the 1970 printing of the 14th edition of the Encyclopædia Britannica (1929–73).

Sagan attended the University of Chicago, where he earned a bachelor’s and a master’s degree in physics in 1955 and 1956, respectively, and a doctorate in astronomy and astrophysics in 1960. From 1960 to 1962 he was a fellow in astronomy at the University of California, Berkeley, and from 1962 to 1968 he worked at Harvard University and the Smithsonian Astrophysical Observatory. His early work focused on the physical conditions of the planets, especially the atmospheres of Venus and Jupiter. During that time he became interested in the possibility of lifebeyond Earth and the search for extraterrestrial intelligence (SETI), a controversial research field he did much to advance. For example, building on earlier work by American chemists Stanley Miller and Harold Urey, he demonstrated that amino acids and nucleic acids—the building blocks of life—could be produced by exposing a mixture of simple chemicals to ultraviolet radiation. Some scientists criticized Sagan’s work, arguing that it was unreasonable to use resources for SETI, a fantasy project that was almost certainly doomed to failure.

On November 21, 2014 I received a letter from Nobel Laureate Harry Kroto and it said:

and you will hear what far smarter people than I have to say on this matter. I agree with them.
