Question

Quizplus · Accepted Answer

Type I supernovae, particularly Type Ia supernovae, are used as standard candles for determining distances to other galaxies. This is because they have a consistent peak luminosity, allowing astronomers to calculate distances based on the observed brightness of the supernova.
