Stargate Atlantis: Season 2, Episode 9

2 - 9: Aurora

When Atlantis's deep-space sensors detect the Aurora, an ancient Atlantian warship, at the edge of the galaxy, Sheppard's team wastes no time hitching a ride to it aboard the Daedalus. Upon their arrival, they encounter a Wraith scout ship. They destroy the scout before it can cause trouble — or so they hope.
