What celestial event provides the brightest standard marker for measuring distances across billions of light-years?
Answer
Type Ia supernovae
Type Ia supernovae result from white dwarfs in binary systems reaching a critical mass, leading to a thermonuclear explosion with a highly consistent peak absolute luminosity, allowing them to be seen across immense cosmic distances.
