i lost a lot of respect for sagen years ago...i saw him as a sell-out....
i always found this interesting....

Dr. John Mack was a professor of psychiatry at Harvard Medical School and a leading authority on the transformative and spiritual aspects of alien encounters. Here is Carl Sagan's "explanation" why people see UFOs quoted from hi book 'The Demon Haunted World': "It appears that all human behavior and experience is well attended by illusory and hallucinatory phenomena. While the relationship of these phenomena to mental illness has been well documented, their role in everyday life has perhaps not been considered enough. Greater understanding of illusions and hallucinations among normal people may provide explanations for experiences otherwise relegated to the uncanny, "extrasensory," or supernatural."
this video cuts out too quickly, in the longer version mack turns around and says "he's just an astronomer for god's sake" or something like that....
Image of the Day: Carl Sagan's Childhood Drawing of His Vision of Outer Space [/size]
Carl Sagan’s passion for exploring worlds beyond our own began as a child growing up in Brooklyn, when a the age of five he began frequenting the New York Public Library to browse books that could give him a better understanding of the stars. He later reflected on the what he discovered: “There was a magnificence to it, a grandeur, a scale which has never left me. Never ever left me.” Sagan’s fixation continued and as a pre-teen he sketched his vision for the future of interstellar space exploration, currently housed in the The Library of Congress. The drawing featured newspaper headlines he predicted would happen in the future. Our favorite: "Epsilon Altair seen fit for human habitation."
Sagan pursued hispassion into adulthood writing later: "All my life, I've wondered about life beyond the earth. On those countless other planets that we think circle other suns, is there also life? Might the beings of other worlds resemble us, or would they be astonishingly different? What would they be made of? In the vast Milky Way galaxy, how common is what we call life? The nature of life on earth and the quest for life elsewhere are the two sides of the same question: the search for who we are."
This is news to my ears. All I ever heard that man say was .. "I believe there is life out there but I do not believe they are coming here." I have him saying this several times from different TV Docs.
Materials From Carl Sagan's College Courses Now Available Online
Are you ready for Astronomy 170 with Professor Sagan?

I'm looking at the very first problem astronomer and science popularizer Carl Sagan assigned to one of his Harvard University classes in 1965. I'm already stumped. Can you do it? Sagan asked his students to derive the equation for the theoretical resolving power of a telescope—that is, the math describing the ability of a telescope to distinguish between two objects. You can see the entire problem set online, thanks to the U.S. Library of Congress, which recently digitized and posted course materials from this and one other class Sagan taught, at Cornell University.
You can find links to all of the materials, including lecture notes and problem sets, in a blog post Special Curator Trevor Owens wrote about the newly digitized material. Sagan may have been best known for his popular science books and TV show, Cosmos, but he also taught college classes for three decades. "He was a mentor and an educator to a range of scientists and non-scientists alike," Owens writes.
Perhaps I would do better in the 1986 Cornell course Owens and his colleagues posted materials for. It's a class about thinking critically about science. In it, Sagan seems to have tried to teach his young charges to think not just about science, but about many things in their everyday lives. In his typed notes-to-self about the class, he recorded discussion prompts about everything from advertising ("What are the messages in cigarette commercials and advertisements?") to statistics ("'Law of averages.' He's 'due' for a hit.") to geopolitical relations ("Each person chooses a historical confrontation between two opposing ideologies which has the fervor of the current confrontation between the United States and the Soviet Union. What lessons may we draw for our own time?").
Seems like there's a lot we may still learn, for our own time, from Professor Sagan.
The next Carl Sagan has already been found: Neil deGrasse Tyson
More than three decades after the debut of “Cosmos: A Personal Voyage,” Carl Sagan’s stunning and iconic exploration of the universe as revealed by science, COSMOS: A SPACETIME ODYSSEY sets off on a new voyage for the stars. Seth MacFarlane (FAMILY GUY, AMERICAN DAD) and Sagan’s original creative collaborators – writer/executive producer Ann Druyan and astronomer Steven Soter – have teamed to conceive a 13-part docu-series that will serve as a successor to the Emmy and Peabody Award-winning original series.
Hosted by renowned astrophysicist Neil deGrasse Tyson, the series will explore how we discovered the laws of nature and found our coordinates in space and time.
Voice of Carl Sagan Stars in Short Film on Humanity's Potential in Space

Humans Explore: We Are Capable of Greatness
The voice of the late Carl Sagan echoes through a new video produced by Space City Films.
The new video, entitled "Humans Explore: We Are Capable of Greatness," is sharply focused on the recent NASA test of the Orion capsule, which launched on a successful unmanned test flight on Dec. 5.
According to Marc Havican of Space City Films: "I wanted to share the kickoff film with you before we release it for Christmas. This first installment is a tribute to Orion and EFT-1, and to the impact that human space exploration has had on humanity."
As noted by the company, "Humans Explore" will be a series of short films and live experiences that they are producing in-house and will be distributing through a dedicated website and various digital outlets.
Hear Carl Sagan discuss aliens and the Bible in new Blank on Blank

Carl Sagan, the iconic scientist behind the original Cosmos TV show, may be gone now, but he left behind voluminous archives of writings and interviews. One such interview was recently sampled for the latest episode of PBS’ Blank on Blank series. Taken from a 1985 interview Sagan did with renowned journalist Studs Terkel, it touches mainly on the possibility of extraterrestrial life, and the differences between science and religion.
“You take those together - lots of places, lots of organic matter, lots of time, and it seems very hard to believe that our poultry little planet is the only one that’s inhabited,” Sagan told Terkel, noting that Earth is located far off in the “boondocks” of the Milky Way galaxy.
Terkel mentioned similarities between science and religion. Sagan acknowledged that both disciplines were after the same thing (“the question of our origins”) but was unsparing in pointing out the scientific flaws of the Bible.
“The natural world around us shows that the Earth, for example, is about 4.6 billion years old, nothing like 6,000 years old. So a literal reading of the Bible is simply mistaken. It’s just wrong,” Sagan said. “As a work of science, it’s flawed. It’s the science of the Babylonians in the sixth century B.C., and we’ve learned something since then.”
Watch the episode, complete with illustrations of Sagan’s aliens and planets, below.
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.

The headline "NASA Scientists Have Covered Up Flat Earth Evidence for 500 Years" really isn't fooling anyone (hopefully). But some bunk stories aren't quite as easy to spot. When fake news, Twitter bots, and conspiracy theories seem legit, how can you know for sure? Leave it everyone's favorite astrophysicist, Carl Sagan, to have a nine-step process perfect for the occasion.
Baloney on Blast
Junk websites know lots of ways to trick you into sharing their false information, which is why being an informed media consumer is more important now than ever — anyone can post almost anything online, after all. That's saying a lot since Carl Sagan thought to address the problem more than 20 years ago. In his book "The Demon-Haunted World: Science as a Candle in the Dark," Sagan offers a method anyone can use to detect what he refers to as "baloney." The 1995 advice — which the L.A. Times called "a spirited defense of science" and "a manifesto for clear thought" — still holds up today.
The Skeptic's Guide to Fake News
Though rampant fake news is hopefully not here to stay, at least Sagan's recipe for critical thinking is. Whenever you come across a questionable claim, parse it out the Sagan way. He lays it out in nine steps in a chapter entitled "The Fine Art of Baloney Detection": www.inf.fu-berlin.de/lehre/pmo/eng/Sagan-Baloney.pdf
1. Wherever possible, there must be independent confirmation of the "facts."
2. Encourage substantive debate on the evidence by knowledgeable proponents of all points of view.
3. Arguments from authority carry little weight — "authorities" have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts.
4. Spin more than one hypothesis. If there's something to be explained, think of all the different ways in which it could be explained. Then think of tests by which you might systematically disprove each of the alternatives. What survives, the hypothesis that resists disproof in this Darwinian selection among "multiple working hypotheses," has a much better chance of being the right answer than if you had simply run with the first idea that caught your fancy.
5. Try not to get overly attached to a hypothesis just because it's yours. It's only a way station in the pursuit of knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives. See if you can find reasons for rejecting it. If you don't, others will.
6. Quantify. If whatever it is you're explaining has some measure, some numerical quantity attached to it, you'll be much better able to discriminate among competing hypotheses. What is vague and qualitative is open to many explanations. Of course there are truths to be sought in the many qualitative issues we are obliged to confront, but finding them is more challenging.
7. If there's a chain of argument, every link in the chain must work (including the premise) — not just most of them.
8. Occam's Razor. This convenient rule-of-thumb urges us, when faced with two hypotheses that explain the data equally well, to choose the simpler.
9. Always ask whether the hypothesis can be, at least in principle, falsified. Propositions that are untestable, unfalsifiable are not worth much. Consider the grand idea that our universe and everything in it is just an elementary particle — an electron, say — in a much bigger cosmos. But if we can never acquire information from outside our universe, is not the idea incapable of disproof? You must be able to check assertions out. Inveterate skeptics must be given the chance to follow your reasoning, to duplicate your experiments and see if they get the same result.
I liked him too but when it comes to the abduction phenomena I think he and other's should've just stuck to astronomy instead of trying to explain something they don't understand or know about themselves.....
i love this video...Dr. John Mack talking about Carl Sagan...
this video cuts out too quickly, in the longer version mack turns around and says "he's just an astronomer for god's sake" or something like that....
Yech..I hate moving and yet I swear I won't resign a lease on this apartment again. I hate the place. I figure scientists for the most part can't accept alien abduction or even encounters. For one thing, it's not happening to them...so that lets that out and for another I figure they think other civilizations would be too civilized to be abducting earthlings. I'd have thought so too...apparently not. You're right...better a nose in a telescope than postulating theories that just aren't anywhere near fact. Course..there IS that whole 'proof' thing we're lacking You would think...all that time with telescopes they would SEE something...but I suppose they're not supposed to. Luck with the move Cliff..I pity you
