  1. Happy Heavenly Birthday. Great picture of Carl. November 9, 1934 — December 20, 1996 was the famous American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to and calculated using the greenhouse effect. A genius who we will never forget.🎂🍾🍹🎈🎆R.I.P.🌹🌹🌹🌹

  2. One of the most important men in the last century , such an inspiration to astronomers and scientists, opened my mind I could listen to him always wish he was my school teacher might have done better 🙂
