And as a ten year old kind of living in rural Wisconsin I had never really met an astronomer. That’s not someone you routinely meet. Whenever people tell me, you know, you don’t really seem like an astronomer. The wonderful next thing to ask is, “How many astronomers do you know?” So my vision of what an astronomer was was this man on this television show, on public television, Carl Sagan. And the thing that Carl did better than anybody else I’d ever seen was this emotional connection to the science. He loved to tell stories. He would tell stories about the history but also it was from him that I learned where all of the atoms in my body come from. The fact that they were all formed in stars. And when Carl talks about that on the show I mean we sort of made a joke that there are these things called “Carl moments” where Carl sort of gazes dramatically off into space and the camera sort of close up, you know, close up on his face. And you can see him sort of emoting at how wonderful this is. And these days, you know, decades later those scenes seem a little bit silly and a little bit contrived. But as a child I was taken along for this incredible emotional journey. Carl was a real rock star. He had this charisma and people would just listen to what he was saying and they would love to follow along with his stories. And that became to me the image of what a scientist was, what an astronomer was, was somebody that could tell the stories of the universe. So I never ended up meeting Carl. I always wanted to. He unfortunately died very young, he died in his early 60s and I was a graduate student at the time. I always figured I would see him at some astronomy conference, I’d somehow, you know, wander past him at one of these scientific meetings and tell him how much that his show had meant to me. But I never got that chance. I never left though that idea, that what a scientist really does is tell stories. It’s about the narrative and it’s about the emotions. And Carl did that better than anyone I’ve ever seen.

If life exists elsewhere in the Universe, would we be able to communicate with it? In this clip from the 1977 CHRISTMAS LECTURES "The planets", Carl Sagan demonstrates how we could send a signal that would make sense to intelligent beings that have evolved independently from us.

What are scientists looking for when searching for alien life? A lot, it turns out: the search for extraterrestrials requires the help from astronomers, planetary scientists, chemists, computer scientists, and geneticists, just to name a few. But are we barking up the wrong carbon-based tree? Could alien life develop in ways we haven't dreamed of here on Earth?

This is a 30 segment from a 1983 Larry King Radio Show. I ask a question at 11 minutes and 30 seconds about one of Jupiter's Moons, Europa. Carl Sagan was an American astronomer, astrophysicist, cosmologist, author, science popularizer and science communicator in astronomy and natural sciences. His contributions were central to the discovery of the high surface temperatures of Venus. However, he is best known for his contributions to the scientific research of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages that were 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. He published more than 600 scientific papers and articles and was author, co-author or editor of more than 20 books. Sagan is known for many of his popular science books, such as The Dragons of Eden, Broca's Brain and Pale Blue Dot, and for the award-winning 1980 television series Cosmos: A Personal Voyage, which he narrated and co-wrote. The most widely watched series in the history of American public television, Cosmos has been seen by at least 500 million people across 60 different countries. The book Cosmos was published to accompany the series. He also wrote the science fiction novel Contact, the basis for a 1997 film of the same name. Sagan always advocated scientific skeptical inquiry and the scientific method, pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). He spent most of his career as a professor of astronomy at Cornell University where he directed the Laboratory for Planetary Studies. Sagan and his works received numerous awards and honors, including the NASA Distinguished Public Service Medal, the National Academy of Sciences Public Welfare Medal, the Pulitzer Prize for General Non-Fiction for his book The Dragons of Eden, and, regarding Cosmos: A Personal Voyage, two Emmy Awards, the Peabody Award and the Hugo Award. He married three times and had five children. After suffering from myelodysplasia, Sagan died of pneumonia at the age of 62 on December 20, 1996.

On Dec 7, 1995, on a JPL television program hosted by Richard Terrile, different commentators (including Carl Sagan) discuss Galileo during its orbit insertion at Jupiter.

On Dec 8, 1992, Carl Sagan discusses, on a JPL television program hosted by Richard Terrile, the second flyby of the Earth by the Galileo spacecraft. (Note: There are much higher quality videos of the Galileo movie of the Earth on youtube if you wish to see that.)

On June 6, 1990, in Washington, DC, Ed Stone and Carl Sagan discuss the findings of the Voyager Missions up to that point, including what later became the photo that made up the Pale Blue Dot.

Sagan's ability to convey his ideas allowed many people to understand the cosmos better—simultaneously emphasizing the value and worthiness of the human race, and the relative insignificance of the Earth in comparison to the Universe. More Carl Sagan: https://www.amazon.com/gp/search?ie=UTF8&tag=tra0c7-20&linkCode=ur2&linkId=9af4feeb12deb35a1542815d27b8b212&camp=1789&creative=9325&index=books&keywords=carl%20sagan He delivered the 1977 series of Royal Institution Christmas Lectures in London. He hosted and, with Ann Druyan, co-wrote and co-produced the highly popular thirteen-part Public Broadcasting Service (PBS) television series Cosmos: A Personal Voyage modeled on Jacob Bronowski's The Ascent of Man. Cosmos covered a wide range of scientific subjects including the origin of life and a perspective of our place in the Universe. The series was first broadcast by the PBS in 1980, winning an Emmy and a Peabody Award. It has been broadcast in more than 60 countries and seen by over 500 million people, making it the most widely watched PBS program in history. In addition, Time magazine ran a cover story about Sagan soon after the show broadcast, referring to him as "creator, chief writer and host-narrator of the new public television series Cosmos, [and] takes the controls of his fantasy spaceship". Sagan was a proponent of the search for extraterrestrial life. He urged the scientific community to listen with radio telescopes for signals from potential intelligent extraterrestrial life-forms. Sagan was so persuasive that by 1982 he was able to get a petition advocating SETI published in the journal Science and signed by 70 scientists including seven Nobel Prize winners. This was a tremendous increase in the respectability of this controversial field. Sagan also helped Frank Drake write the Arecibo message, a radio message beamed into space from the Arecibo radio telescope on November 16, 1974, aimed at informing potential extraterrestrials about Earth. Sagan was chief technology officer of the professional planetary research journal Icarus for twelve years. He co-founded The Planetary Society, the largest space-interest group in the world, with over 100,000 members in more than 149 countries, and was a member of the SETI Institute Board of Trustees. Sagan served as Chairman of the Division for Planetary Science of the American Astronomical Society, as President of the Planetology Section of the American Geophysical Union, and as Chairman of the Astronomy Section of the American Association for the Advancement of Science (AAAS). At the height of the Cold War, Sagan became involved in public awareness efforts for the effects of nuclear war when a mathematical climate model suggested that a substantial nuclear exchange could upset the delicate balance of life on Earth. He was one of five authors -- the "S" -- of the "TTAPS" report, as the research paper came to be known. He eventually co-authored the scientific paper hypothesizing a global nuclear winter following nuclear war. He also co-authored the book A Path Where No Man Thought: Nuclear Winter and the End of the Arms Race, a comprehensive examination of the phenomenon of nuclear winter. Sagan also wrote books to popularize science, such as Cosmos, which reflected and expanded upon some of the themes of A Personal Voyage and became the best-selling science book ever published in English; The Dragons of Eden: Speculations on the Evolution of Human Intelligence, which won a Pulitzer Prize; and Broca's Brain: Reflections on the Romance of Science. Sagan also wrote the best-selling science fiction novel Contact in 1985, based on a film treatment he wrote with his wife in 1979, but he did not live to see the book's 1997 motion picture adaptation, which starred Jodie Foster and won the 1998 Hugo Award for Best Dramatic Presentation. http://en.wikipedia.org/wiki/Carl_sagan

1977 Carl Sagan Christmas Lectures 2, about the outer solar system and life. In his second Christmas Lecture, Carl Sagan travels beyond Earth to explore the possibility of life in outer space. To find the answer, he looks back to the early stages of the development of our atmosphere. The hydrogen from this atmosphere has since escaped to space from Earth, but not from bigger planets like Jupiter. When the hydrogen-rich gases of the early Earth are mixed together and supplied with energy, the essential molecular building blocks of the proteins and nucleic acids are formed. As Sagan suggests, although this process no longer occurs on Earth, such organic chemistry should be occurring in the outer solar system on Jupiter, and Titan, Saturn's largest moon. The NASA twin spacecraft Voyager 1 and 2, launched a few months prior to these Lectures in 1977, were sent to space to explore this hypothesis.

In this classic interview from 1989, Dr. Carl Sagan, possibly the greatest populariser of fundamental science in modern history, has a conversation with CNN founder and environmental philanthropist Ted Turner. Ted Turner, like many others, acknowledged Carl Sagan's message about the importance of scientific reason about difficult matters such as environmental destruction and the threat of nuclear war early on and is responsible, in part, in drawing attention to the issue of environmental destruction to the masses. Turner undoubtedly monopolised the cable television sector making CNN one of the most powerful forms of mass media on earth. Fully aware that his financial gain was the direct result of the high technology of the time, Turner had responsibility to interview one of the leading scientists in the public sphere back then. Carl Sagan realised that part of the problem of nuclear war and global warming was the lack of understanding that the damage they can cause are both non-mutually exclusive to the countries that are responsible and the countries which are not responsible. In other words, greenhouse gases and radioactive smoke and dust do not recognise borders between countries, CO2 and radiation do not carry passports. Carl Sagan's work in the consequences of nuclear winter, which he derived mainly by Mie Scattering calculations of dust molecules in Martian dust storms, predicted to happen under certain conditions following a nuclear war was a key part in the development of the theory of Nuclear Winter which is one of the leading arguments against the perceived stability in the policy of Mutually Assured Destruction (M.A.D). Other scenarios, such as atmospheric irradiation, which would permanently destroy the Ozonosphere, and long term radioactive fallout are probably more likely, and more disastrous, scenarios making Carl's predictions somewhat optimistic. Moreover, human made climate change induced by CO2 and Methane emissions by intense industrial society has been predicted, using computer modelling at MIT and Caltech and others, showing a runaway global warming effect if Arctic and Antarctic permafrost is melted which would release huge amounts of trapped methane into the atmosphere warming the earth by perhaps 5 degrees or more at the equator, up to 12 degrees at the poles which would cause sea and ocean levels everywhere to rise as well as shifting of ocean and air currents causing unpredictable and much more energetic weather formations. Continuous Ozone depletion and water acidification and contamination are also serious issues as is the issue of fresh water shortage, which will tally the consequences of climate change to everyday human life. Carl Sagan shows us that our technological progress, unregulated, gives humanity the power to do utter devastation to the environment and to the human species itself. logically regulated however, Carl has taught us that the proper use of technology and the proper action to scientific knowledge can also do great good to the soften the impact of a technical civilization on the environment and towards helping the human community on a global scale. We should start taking Carl Sagan's and many others' example of thinking of the border divides between countries as imaginary to avoid global catastrophe by the threats of warfare by weapons of mass destruction and by global warming and environmental destruction. The silver lining of such actions would be, as Carl Sagan observes, the driving force that unites the human species to become a planetary civilization. Other Issues such as global poverty and the importance of science and mathematics education, fundamental science research and exploration are discussed and some more esoteric topics are discussed as well such as life on other planets, the philosophical implications of future technologies, the existence/non-existence of God(s) and the possible future of the human species.
