Carl Edward Sagan was born on the 9th of November 1934 in Brooklyn, USA. An American astronomer is one of the most prominent contributors to the simplification of astronomy, astrophysics and other natural sciences. He also played an important role in the creation of the US space agency NASA. He played a leading role in promoting the search for intelligent creatures outside the globe. He studied physics at the University of Chicago, and in 1960 received the title of Doctor of Astronomy and Astrophysics. He taught at Harvard University, in 1968 he moved to Cornell University, where he became a university professor in 1971. Sagan edited and presented the television program "The Universe", in which he explained astronomy, and the program was shown in many countries. He has been awarded the NASA Medal (twice), the Arster Medal, and the Pulitzer Prize. He wrote a novel Tawassul in 1985 and was represented in a movie in 1997. The most important thing that distinguishes Sagan is his major contributions to the simplification of space and astronomy sciences to the general public, and this may have led to the success of most of his books, most notably: 1- The Universe 2- Planet Earth A pale blue dot 3- Billions and Billions 4 - A world inhabited by demons 5 - Dragons of Eden Sagan believed that the universe contained one or more life outside the framework of planet Earth. This is based on the enormous size of the universe, and his idea simply says that the possibility of the conditions suitable for life in a place other than planet Earth is possible, as long as we are talking about a universe that includes countless numbers of galaxies, stars and planets. He also believed that prime numbers are cosmic numbers. Sagan passed away on December 20, 1996
