Battlestar Galactica, or BSG, is a franchise of science fiction films and television series, the first of which was produced in 1978. A series of book adaptations, original novels, comic books and video games have also been based on the concept. A reimagined miniseries aired in 2003, with a regular television series starting in 2004. All of the Battlestar Galactica productions share the same premise: In a distant part of the universe, a civilization of humans live on planets known as the Twelve Colonies. In the past, the Colonies have been at war with a cybernetic race known as the Cylons. With the help (knowing or unknowing) of a human named Baltar, the Cylons launch a sudden sneak attack on the Colonies, laying waste to the planets and devastating their populations. A few thousand of the human survivors flee into space aboard any spacecraft they can reach. Of all the Colonial Fleet, the Battlestar Galactica appears to be the only military ship that survived the attack.
