Supernovae are among the most energetic transient objects in the Universe. They briefly outshine entire galaxies of stars, and are responsible for the formation of almost all of the elements heavier than helium. They dominate the energetics of the interstellar medium. Type Ia supernovae are the most accurate distance indicators for external galaxies.

超新星是宇宙中能量最高的瞬变天体之一。 它们的亮度短暂地超过了整个恒星星系，并且是几乎所有比氦重的元素形成的原因。它们支配着星际介质的能量学。Ia型超新星是外部星系最精确的距离指示器。
