In Star Wars
In Episode IV: A New Hope, the Death Star served as a space station of the evil Galactic Empire. It was a spherical structure that resembled a moon, and functioned like one. It had the ability to control its gravity and inertia, allowing it orbit any planet at will, or remain stationary. It also held a large cannon located at a "crater"-like intrusion that could easily destroy planets. It was eventually destroyed by Luke Skywalker when the Rebel army attacked.

The Death Star would eventually be rebuilt in Episode VI: Return of the Jedi. During the events of the story, it was still under construction. However, to prevent the Rebel Army from interfering again, the second Death Star was protected by an impenetrable shield on the nearby forest moon of Endor. This version retains a fully functional crater-like cannon, even while being under construction. Even with all of these new defense systems, the Rebels were still able to destroy it.

Trivia

 * Sometimes, the Death Star can be also called the "Pig Station" in some text on the boxes of merchandise.
 * The first 20 levels have been updated in the Facebook game of Angry Birds Star Wars on February 25, 2013, and the other levels came on April 2, 2013.
