The series resumes the story of the "Lost City" and "New Order" episodes of SG-1, where a military team led by Colonel (now Brigadier General) Jack O'Neill, Dr. Daniel Jackson, Major (now Lt.

Colonel) Samantha Carter and the Jaffa Teal'c, use an ancient alien artifact called the Stargate to travel to different planets to explore and find new technology.

Stargate Atlantis' finale episode premiered in the United States on the Sci Fi Channel on January 9, 2009.
