In the 12th episode of Cosmos, which aired on December 14, 1980, the program’s co-creator and host Carl Sagan introduced television viewers to astronomer Frank Drake’s eponymous equation. Using it, he calculated the potential number of advanced civilizations in the Milky Way that could contact us using the extraterrestrial equivalent of our modern radio-communications technology. Sagan’s estimate ranged from “a pitiful few” to millions.
“That's just a very specific and strong assumption,” says astronomer David Kipping of Columbia University. “I don't see any evidence that that's a safe bet to be making.”

Americans desperately wanted an explanation, even if that explanation was a bit out there or just a way of projecting politics. Then, in the 1990s, came along the Internet and the golden age of theory.

Eisenhower and extraterrestrials? Film explores urban legend
Written and directed by Christopher Munch, "The 11th Green" begins on slow simmer and eventually arrives at an emotional boil as it floats back and forth through time to explore a curious proposition: that former President Dwight D. Eisenhower was not only interested in but also had contact with extraterrestrials.
