About Carl Sagan
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an 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. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

The Cosmos extends, for all practical purposes, forever. After a brief and sedentary hiatus we are resuming our ancient nomadic way of life. Our remote descendants, safely arrayed on many worlds though through the Solar System and beyond, will be unified by their common heritage, by their regard for their home planet, and by knowledge that, whatever other life may be, the only humans in all the Universe come from Earth.
