How can we use Type Ia supernovae to measure the distance to faraway galaxies?
Answer 1
Jasmine Martin
Type Ia supernovae serve as ‘standard candles’ in astronomy because they have a consistent intrinsic brightness. By comparing the observed brightness of a Type Ia supernova to its known intrinsic brightness, astronomers can calculate its distance using the inverse square law of light. This method allows for accurate measurements of distances to faraway galaxies.
