Question

Quizplus · Accepted Answer

A white dwarf supernova is a very luminous standard candle, meaning that we can use its brightness to determine its distance. This information is crucial for calibrating Hubble's Law, which relates the distance of a galaxy to its redshift (a measure of how fast it is moving away from us). The brightness of a white dwarf supernova allows us to accurately determine the distance to the galaxy hosting it, which in turn helps us to better understand the relationship between galaxy distance and redshift.
