How are Cepheid variable stars used in measuring distances in astronomy?
Cepheid variable stars are used in astronomy to measure distances by observing their pulsation periods. The longer the period of pulsation, the brighter the star, allowing astronomers to calculate the star's true brightness and therefore its distance from Earth. This method, known as the period-luminosity relationship, helps determine distances to faraway galaxies and other celestial objects.
How are cepheid variables utilized in the process of determining distances in astronomy?
Cepheid variables are used in astronomy to measure distances to faraway objects. By observing the pulsation period of these stars, astronomers can calculate their intrinsic brightness. By comparing this to their apparent brightness, they can determine how far away the star is, helping to map the vast distances of the universe.
