For the mid-23rd century slang term, please see Nova (slang).

A nova was an event in which a star dramatically increased in brightness for a relatively short period of time.

The term nova was also occasionally used to describe supernovae, which are a separate type of event.

A supernova could be induced by firing an antimatter missile into a nova's core. (DIS: "Such Sweet Sorrow") After finding an entire solar system reduced to rubble and asteroids, James T. Kirk stated that only a nova could do such a thing. (TOS: "The Doomsday Machine")
