Questions are raised about the search for intelligent life beyond the Earth, with UFOs and other close encounters refuted in favor of communications through SETI and radio telescope such as the Arecibo Observatory. The probability of technically advanced civilizations existing elsewhere in the Milky Way is interpreted using the Drake equation and a future hypothetical Encyclopedia Galactica is discussed as a repository of information about other worlds in the galaxy. The Cosmos Update notes that there have been fewer sightings of UFOs and more stories of abductions, while mentioning the META scanning the skies for signals.

Science is more than a body of knowledge; it’s a way of thinking, a way if skeptically interrogating the universe.  If we do not ask skeptical questions, then we’re up for grabs.
Greatly missed… what a scientist !!
i love Carl Sagan, its a shame he died in the same year popular hand held cameras seem to have come common place. would say without a doubt upon my research into his shows and mindset that he would have a different outlook on life in the cosmos if he were to be alive today.
