Lightsaber Pulsar

The Lightsaber Pulsar, originally BXC 2934, was a pulsar located 59 light years from Qruash. It regularly emitted a blue jet of material outward from its spinning core. At the advent of the lightsaber, the pulsar was given its name due to its appearance to the new weapon. It was later classified as H250, as an honorary addition to the Hullian system.

Interestingly enough, during the era of the Galactic Empire and the rule of the Sith, the jet turned to blood red and returned to blue-green during the New Jedi Order.
