Quizplus · Accepted Answer

Type Ia supernovae are the most powerful and brightest explosions in the universe, making them visible from extremely far distances. They have a consistent luminosity, which allows astronomers to use them as standard candles to measure distances. This method has been used to estimate the distance to remote galaxies and helped discover the accelerating expansion of the universe.
