Cosmos Episode 12: Encyclopedia Galactica Part 1 of 7

Are there alien intelligences? How could we communicate with them? What about UFOs? The answers to these questions take us to Egypt to decode ancient hieroglyphics, to the largest radio telescope on Earth and, in the Spaceship of the Imagination, to visit other civilizations in space.

Dr. Sagan answers questions such as: "What is the life span of a planetary civilization?" and "Will we one day hook up with a network of civilizations in the Milky Way galaxy?"

Thank you for posting this. Carl Sagan was awesome and he is very missed.

If aliens came to Earth they would say "FUCK WMG"

Go away fool.

I just thought of something. All forms of creatures on Earth have a sense of compassion for one another. Even the most "alien" of creatures, down in the depths of the ocean show amazing care for their children. One can only assume that "they" too show great care and companionship with one another. Otherwise, they never would've made it so far :) Who knows, maybe an "Interracial" couple, millions of years from now will be a "Inter-galactic" couple. :)

An interracial couple in 1961, especially a black man with a white woman? They're lucky it was New Hampshire and not Mississippi or Alabama.

An inter-racial couple in 1961 seem less likely then Alien vistors

@biohazardcel

it takes alot of writing to make one of these episodes, mountains of research. He did have a life :D

[biohazardcel]

why couldn't this series be 100 episodes... :(

Having a long standing fascinations with UFOs, I know all about the Betty and Barney Hill case. I think it was the first ever modern documented alien abduction case, and I strongly believe it's real!

I saw this particular episode when I was a kid, and I remember that I was scared to death by the abduction sequence! I think I slept under my bed sheets that night.

Carl Sagan is going to go into history as one of the greatest people to ever live. If by the slightest chance that our civilization does not destroy itself, Carl will always be remembered as someone who reminded human beings to work together. We do after all only occupy the smallest amount of space on this "pale blue dot". :)
