What descriptive term might appear in less formal writing to emphasize the sudden appearance and immense light output of a supernova?

Answer

gigantic stellar flare

When astronomers or writers seek alternatives in less formal contexts, descriptive phrases that emphasize the visual impact of the event are sometimes employed. One such term mentioned that focuses on the transient nature and overwhelming luminosity output is 'gigantic stellar flare.' While this term conveys immensity, it is generally less precise than 'supernova' and might be used where dramatic effect or accessibility for a general audience is prioritized over exact scientific classification.
