Astronomer Dr. Carl Sagan is host and narrator of this 13-hour
series that originally aired on Public Broadcasting Stations
in the United States.
Dr. Sagan describes the universe in a way that appeals to
a mass audience, by using Earth as a reference point, by speaking
in terms intelligible to non-scientific people, by relating
the exploration of space to that of the Earth by pioneers
of old, and by citing such Earth legends as the Library of
Alexandria as metaphors for space-related future events.
Among Dr. Sagan's favorite topics are the origins of life,
the search for life on Mars, the infernal composition of the
atmosphere of Venus and a warning about a similar effect taking
place on Earth due to global pollution and the "greenhouse
effect", the lives of stars, interstellar travel and
the effects of attaining the speed of light, the danger of
mankind technologically self-destructing, and the search,
using radio technology, for intelligent life in deep space.
