A Force-induced supernova

"Without precise calculations, we'd fly right through a star, bounce too close to a supernova, and that'd end your trip real quick, wouldn't it?"
Han Solo, to Luke Skywalker[1]

A supernova occurred when a giant star ceased to fuse light elements into heavier elemental products. The loss of internal heating allowed the star to collapse onto itself to form a neutron star or a black hole. Supernova could happen naturally or be induced by a superweapon.

Many systems had been destroyed or rendered uninhabitable after their suns exploded. A supernova had also killed life in neighboring systems, and thus interstellar evacuations had been necessary many times in galactic history. In a placid spiral galaxy as large as the extent of the Galactic Empire, approximately three supernovae occurred every century.[source?] Nonetheless, gas and dust within the plane of the galactic disk could limit a supernova's visibility to a few thousand light years.

If a star was massive enough to perish in a supernova explosion, it produced, in its final stages of nuclear fusion, large amounts of heavy elements in its core. The supernova then scattered these elements into the surrounding nebulae.
