Quizplus · Accepted Answer

Type I supernovae, specifically Type Ia, are among the brightest objects in the universe when they occur, outshining entire galaxies for a short time. RR Lyrae stars and Type II supernovae are also bright, but Type I supernovae, due to their consistent maximum luminosity, are used as standard candles for measuring astronomical distances.
