The Sci Fi Channel has given a fifth-season renewal to Stargate: Atlantis, according to Variety, commissioning 20 new episodes.

"Atlantis truly came out from under the shadow of its sister series this year and proved that it's a hit in its own right," said Sci Fi's Mark Stern, exec veep of original programming. The show's predecessor, Stargate SG-1, ran for 10 seasons on Sci Fi before completing its run last year.

Stern said Sci Fi is in "a good place" when it comes to scripted original series, anticipating lots of buzz for the final 22-episode season of Battlestar Galactica, now in production.
