Cosmos: A Personal Voyage

S01E12 Encyclopedia Galactica

Are there extraterrestrial beings? How might we establish contact with them? And what about unidentified flying objects? To explore these mysteries, we journey to Egypt to interpret ancient hieroglyphs, visit the largest radio telescope on the planet, and travel aboard the Spaceship of the Imagination to encounter other civilizations beyond our world. Dr. Sagan addresses intriguing queries like, "How long does a planetary civilization last?" and "Is it possible that we will connect with a network of civilizations within the Milky Way?"
