This stems from Carl. Sagan's remarkable dual identity-he is both a Pulitzer Prize-winning writer and a true scientist. The following is an excerpt from his life:
"Carl Sagan (1934-1996), director of the Planetary Research Center at Cornell University, professor of the David Duncan Society for Astronomy and Space Science, California Institute of Technology Jet Propulsion Laboratory An outstanding scientist. He is also one of the founders and presidents of a world-wide space research organization and the American Planetary Research Society. Dr. Carl Sagan is not only an outstanding astronomer who has made many important contributions, He is also an outstanding science master. His excellent science work "The Flying Dragon of Eden" won the American Pulitzer Prize, which is the highest award of the National Academy of Sciences for his achievements in the field of public understanding of science. He is also the Professor of Astronomy and Space Science and the Director of the Planetary Research Laboratory of the "David Duncan" Chair at Cornell University.
Sagan is an active supporter of space exploration, and he is very helpful to most unmanned exploration projects to explore the solar system. Contributions. Including the first detailed photos of Mars, the "Sailor 9" spacecraft that proved it to be a desolate and barren planet; the "Viking" orbiter that searches for life on the surface of Mars (its mission was not successful), and Landing devices; Pioneer and Voyager probes that first revealed the mysteries of the outer planets of the sun and their satellites; and the Galileo spacecraft that is returning extremely clear images of Jupiter and Jupiter's satellites.
Sagan's work has changed our understanding of where the earth is in the universe. He inferred that due to the strong greenhouse effect, the surface of Venus is actually terribly hot—people once thought that it might be a place with a pleasant climate. He also pointed out that a large number of complex carbon-based chemical components in the universe may be the primitive forms of other life. Sagan also collected evidence for the existence of organic molecules similar to life groups in Titan’s atmosphere. This work was excellently confirmed by the Voyager probe in the 1980s.
Throughout Sagan's career, he has always endorsed the importance of searching for signs of extraterrestrial life. At Cornell University, he pioneered a new field of "outer space biology"-this is the study of possible extraterrestrial biochemistry and life forms. He once designed a metal plate containing greeting messages from the people of the earth, and this metal plate is flying into interstellar space with the "Pioneer" 10 spacecraft (there are two more complex recording records being accompanied by two "travelers" Flight to other stars). Sagan worked with various collaborators (including Paul Horowitz of Harvard University) to support a plan to use radio telescopes to "listen" to extraterrestrial signals, which may originate from an extraterrestrial intelligent civilization. "
This is the wonderful life story behind the subtitle "to carl" that appears in the bottom right corner of the starry sky at the end of the film. It is not only his story that makes us awe at this scientist who died of bone marrow cancer in 1996. Wonderful scientific interpretation, the most important thing is the strong desire, curiosity and courage of people who are full of the whole story to explore the truth, like an inextinguishable torch, making people willing to pay no matter what the price, even if it is an unknown destiny, is the most Precious feelings, even life. In the
last topic, it has been 10 years in a blink of an eye. I have forgotten that Judy Foster has the most beautiful pair of green eyes.
