Carl Edward Sagan was an American science communicator, author, astrobiologist, astrophysicist, cosmologist, planetary scientist, and astronomer. His well known scientific contribution is his research on extraterrestrial life.
Another of his contributions is the experimental demonstration of the production of amino through radiation with the help of primary chemicals. He was also involved in assembling the first physical messages to be bent into space.
They were called the Voyager Golden Record and the Pioneer Plaque, which are regarded as universal messages that could potentially be deciphered by extraterrestrial beings if they were to find them one day.
He was also one of the first to propose the now widely accepted theory that the high temperatures on the surface of the planet Venus is attributed to the Greenhouse effect that we are also facing on earth. He is also the author of the science fiction novel “Contact” adapted to a movie in 1997.
