Abstract
Carl Sagan explores the universe in this monumental cosmic journey. A fascinating blend of science, education, and entertainment that covers everything from the cells which build life to the Big Bang that started it all. The cosmos is all that is, ever was, or ever will be... we are, all of us, made of star-stuff.
Cosmos tells the fascinating story of how nearly fifteen billion years of cosmis evolution transformed matter and life into consciousness, of how science and civilisation grew up together and of the forces and individuals who helped shape modern science.
Astronomer Dr Carl Sagan is host and narrator of this amazing 13 hour series, now digitally remaster, restored and enhanced. With topics including the origins of life, the search for extra-terrestrial life, the "greenhouse effect", the lives of stars, interstellar travel and the effects of attaining the speed of light, this is a fascinating insight into humanity and the universe.

Description
Episode 7: The Backbone of Night
Carl Sagan teaches students in a classroom in his childhood home in Brooklyn, New York, which leads into a history of the different mythologies about stars and the gradual revelation of their true nature. In ancient Greece, some philosophers (Aristarchus of Samos, Thales of Miletus, Anaximander, Theodorus of Samos, Empedocles, Democritus) freely pursue scientific knowledge, while others (Plato, Aristotle, and the Pythagoreans) advocate slavery and epistemic secrecy. During the episode, Sagan correctly gives the students the prediction that astronomers will confirm the existence of exoplanets within their lifetime.
Episode 8: Journeys in Space and Time
Ideas about time and space are explored in the changes that constellations undergo over time, the redshift and blueshift measured in interstellar objects, time dilation in Albert Einstein's theory of relativity, the designs of both Leonardo da Vinci and spacecraft that could travel near light speed, time travel and its hypothetical effects on human history, the origins of the Solar System, the history of life, and the immensity of space. In Cosmos Update, the idea of faster-than-light travel by wormholes (researched by Kip Thorne and shown in Sagan's novel Contact) is discussed.
Episode 9: The Lives of Stars
The simple act of making an apple pie is extrapolated into the atoms and subatomic particles (electrons, protons, and neutrons) necessary. Many of the ingredients necessary are formed of chemical elements formed in the life and deaths of stars (such as our own Sun), resulting in massive red giants and supernovae or collapsing into white dwarfs, neutron stars, pulsars, and even black holes. These produce all sorts of phenomena, such as radioactivity, cosmic rays, and even the curving of spacetime by gravity. Cosmos Update mentions the supernova SN 1987A and neutrino astronomy.
