What “nova” means

Wiktionary · Wikipedia

nova/ˈnəʊ.və/

  • nounAny sudden brightening of a previously inconspicuous star.
Full entry on Wiktionary →

A nova is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star that slowly fades over weeks or months. All observed novae involve white dwarfs in close binary systems, but causes of the dramatic appearance of a nova vary, depending on the circumstances of the two progenitor stars. The main sub-classes of novae are classical novae, recurrent novae (RNe), and dwarf novae. They are all considered to be cataclysmic variable stars.
