By 1974, the controversy surrounding Velikovsky's work had permeated US society to the point where the American Association for the Advancement of Science felt obliged to address the situation, as they had previously done in relation to UFOs, and devoted a scientific session to Velikovsky, featuring ( among others ) Velikovsky himself and Professor Carl Sagan.

In his later years as a writer and scientist, Sagan would often draw on his childhood memories to illustrate scientific points, as he did in his book, Shadows of Forgotten Ancestors.

Sagan describes his parents ' influence on his later thinking:

Dr. Carl Sagan, using optimistic numbers, suggested as many as one million communicating civilizations in the Milky Way in 1966, though he later suggested that the actual number could be far smaller.

In 1960, Singer commented in an article in Astronautics on the hypothesis of Iosif Shklovsky ( later mentioned in a 1966 book by Carl Sagan and Shklovsky ) that the orbit of the Martian moon Phobos suggests that it is hollow, which implies it is of artificial origin.

The particles were never observed to rise above 6 km and when combined with scavenging by clouds gave the smoke a short residency time in the atmosphere and localized its effects ; Professor Carl Sagan of the Turco, Toon, Ackerman, Pollack, Sagan ( TTAPS ) study hypothesized in January 1991 that enough smoke from the fires " might get so high as to disrupt agriculture in much of South Asia ...." Sagan later conceded in his book The Demon-Haunted World that this prediction did not turn out to be correct: " it was pitch black at noon and temperatures dropped 4 °– 6 ° C over the Persian Gulf, but not much smoke reached stratospheric altitudes and Asia was spared.

Parts of Heaven and Hell were later used as the theme to the PBS television series Cosmos by Carl Sagan.

A few years later Abbott Ladolf of Sagan lists John of Nepomuk in the catalog of Sagan abbots, completed in 1398, as well as in the treatise " De longævo schismate ", lib.

Soviet astronomer Iosif Shklovskii wrote the pioneering book in the field Universe, Life, Intelligence ( 1962 ), which was expanded upon by American astronomer Carl Sagan as the best-selling Intelligent Life in the Universe ( 1966 ).

Planetary astronomer Carl Sagan wrote:

Carl Edward Sagan (; November 9, 1934 – December 20, 1996 ) was an American astronomer, astrophysicist, cosmologist, author, science popularizer, and science communicator in astronomy and natural sciences.

Carl Sagan was born in Brooklyn, New York ,.

His father, Sam Sagan, was an immigrant garment worker from Russia.

Both Sagan and his sister agree that their father was not especially religious, but that their mother " definitely believed in God, and was active in the temple ... and served only Kosher meat ".

From 1960 to 1962 Sagan was a Miller Fellow at the University of California, Berkeley.

From 1972 to 1981, Sagan was the Associate Director of the Center for Radio Physics and Space Research at Cornell.

Sagan was associated with the U. S. space program from its inception.

Sagan assembled the first physical message that was sent into space: a gold-anodized plaque, attached to the space probe Pioneer 10, launched in 1972.

Sagan taught a course on critical thinking at Cornell University until he died in 1996 from pneumonia, a few months after finding that he was in remission of myelodysplastic syndrome.

Isaac Asimov described Minsky as one of only two people he would admit were more intelligent than he was, the other being Carl Sagan.
