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.

There’s plenty of housework to be done here on Earth, and our commitment to it must be steadfast. But we’re the kind of species that needs a frontier — for fundamental biological reasons. Every time humanity stretches itself and turns a new corner, it receives a jolt of productive vitality that can carry it for centuries.
Hay un geocentrismo práctico en nuestra vida diaria. Todavía hablamos del Sol que sale y se pone, en lugar de hablar de una Tierra que gira. Todavía pensamos en un universo organizado para nuestro beneficio y poblado tan sólo por nosotros. La exploración del espacio, en este sentido, nos hará ser un poco más humildes.

The old man made himself look hard at the Raven and saw that it was not a great bird from the sky but the work of men like himself. This first encounter turned out to be peaceful.
