Carl Edward Sagan was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science populariser and science communicator. He is best known for his contributions to the scientific research of extraterrestrial life.
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.
 |
| The Voyager Golden Record - Contains 115 images including a calibration image along with a variety of natural sounds including noises made by thunder, waves etc and animals. It also features musicals selections from different countries and era's and spoken greetings in 59 different languages. |
 |
| The Pioneer Plaque - a pair of gold-anodised aluminium plaques which were placed onboard the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft featuring a pictorial message incase either spacecraft was intercepted by extraterrestrial life. The plaque included a hyperfine transition of neutral hydrogen, figures of a man and woman, relative position of the sun to the centre of the galaxy and 14 pulsars, the solar system and a silhouette of the spacecraft. |
He is the author/editor of more than 20 books including:
. The Dragons of Eden
. Broca's Brain
. Pale blue Dot
. Cosmos
. Contact
I love space, I love the idea that there's so much more than this little life on this little planet. I think thats what attracted me to Sagan the most really, just a chance to explore and delve deeper into space and astrology and hopefully learn some interesting things along the way.
