A supernova is the explosion of a star -- the largest explosion that takes place in space. A supernova is a transient astronomical event that occurs during the last stellar evolutionary historical supernovae are known simply by the year they occurred: sn 185, sn 1006, sn 1054, sn 1572 type ia supernovae follow a characteristic light curve—the graph of luminosity as a function of time—after the event.
