The Canopus wormhole resides near the Korax nebula.
Galactica cannot immediately investigate the transmissions further. In the path to the wormhole's entrance is a planet inhabited by Cylons. The planet, home to the city of Tessida, is used as a military computer center (Battlestar Galactica: Cylon Apocalypse #1).
Following the Battle of Tessida, Adama deploys a gravitic warhead to collapse the wormhole after the Fleet traverses it, hoping that doing so brings them closer to the Thirteenth Colony while preventing the Cylons from doing likewise (Battlestar Galactica: Cylon Apocalypse #4).
