n. pl. su·per·no·vae (-vē) or su·per·no·vas
A rare celestial phenomenon involving the explosion of a star and resulting in an extremely bright, short-lived object that emits vast amounts of energy. Depending on the type of supernova, the explosion may completely destroy the star, or the stellar core may survive to become a neutron star.

n, pl -vae (-viː) or -vas
(Astronomy) a star that explodes catastrophically owing to either instabilities following the exhaustion of its nuclear fuel or gravitational collapse following the accretion of matter from an orbiting companion star, becoming for a few days up to one hundred million times brighter than the sun. The expanding shell of debris (the supernova remnant) creates a nebula that radiates radio waves, X-rays, and light, for hundreds or thousands of years. Compare nova
