The cataclysmic explosion of a massive star. A Supernova may, for a short time, out shine an entire galaxy of a hundred billion ordinary stars. It is thought to leave behind a highly compressed neutron star.

Violent explosion of a star. The star is destroyed, with a remnant forming a neutron star (pulsar) or black hole (collapsar) depending on the residual mass.

There are generally two forms of supernova. One results at the end of the life of a star with at least about eight solar masses, which in a series of progressively shorter-lived and less efficient thermonuclear reactions generates ever heavier chemical elements in layers about the core. Effectively this is a star that lives fast and dies young. When each step in the process chokes up the core with nuclear "ash", contractions follow under gravity, driving up temperatures until they are sufficient to synthesise the next heavy element from this waste product. When the core fills with iron, the end point is reached; it takes more energy to fuse iron into anything heavier than the fusion reaction produces. At this point the star collapses, driving temperatures into perhaps twelve figures

A spell used in Final Fantasy VII by the final boss Sephiroth. He summons a massive comet into the solar system, which proceeds to demolish the outer planets up to Jupiter. It then crashes into the sun, causing it to go supernova and destroy Mercury and Venus. As the sun continuously expands toward Earth, Sephiroth basks in the sun itself, while your party is damaged heavily. The animation for the spell takes nearly 2 minutes to complete.
