Black hole

A super-massive black hole that stars rotated around was located in the center of the galaxy. It was called the Galactic Centre.

By 40 BBY, it was possible to take pictures of a black hole from a point just shy of its event horizon. Obi-Wan's friend Jape sent Obi-Wan such images.

The Akkadese Maelstrom sub-region around the Kessel sector contained a number of black holes, the most dangerous being The Maw. A cell of the criminal organization Crimson Dawn known as Beckett's gang, along with his partner Lando Calrissian and his female droid L3-37, fell in that black hole and were about to be sucked in, until they used the coaxium as a power source for the Millennium Falcon to escape the hole's gravity.

Shortly after the formation of the Galactic Empire, Lieutenant Commander Orson Krennic, accompanied by Mas Amedda and several others, traveled to a binary black hole formation known as the Hero Twins, where they tested a prototype version of the superlaser that would eventually be installed on the Empire's planet-destroying battle station, the Death Star, by firing it at the deceased stars.

The Executor-class Star Dreadnought Arbitrator, while attempting to escape a New Republic fleet, accidentally input erroneous hyperspace coordinates into its navicomputer, which caused it to exit hyperspace near a black hole, pulling the ship in and destroying it.
