Stargate SG-1 is the first television series created after the movie Stargate. The main subject of the movie is the discovery of an ancient artifact in Egypt, near the great pyramids. The device proves to be ancient and functional, being able to create a wormhole and work like an instantaneous transporter between Earth and numerous alien planets across the galaxy, inhabited or not.
SG-1 has ten seasons of more than twenty episodes each, made from 1997 to 2007. The story begins with a retired colonel from the United States Airforce by the name of Jack O'Neill, who receives the proposal to return to his job and continue his missions through the gate. SG-1 is actually the name of a team composed from Major Samantha Carter (scientist), Doctor Daniel Jackson (archeologist) and Teal’c.
Teal’c is an alien, a former Jaffa (warriors who serve a parasite race that consider themselves as gods), who rebelled and took the side of humans. The whole series is about the war between humans and the parasite race, the Goa’uld. The race is in fact one of snakes that use human bodies as hosts. Humans make some good allies, such as the Asgard and the Tok' ra in the fight against their enemies. The Goa’uld seeks to rule and conquer the galaxy and they enslave humans that inhabit various planets in the process. Names like Ra, Anubis, Baal, Apophis are common in the series, as the Goa’uld gods are actually the gods in the Egyptian mythology.
The human team leader is Colonel Jack O'Neill and the person in Charge with the Stargate program is General Hammond. The location where the device is maintained in a functioning state is a secret base inside the Cheyenne Mountain and the operations are classified.
Stargate SG-1 is one of the best science-fiction television series ever made and had an enormous popularity. It was followed by the Atlantis and Universe series, both with fresh actors.
