Cepheid Variables
Cepheid Variables are a type of pulsating star that has a predictable relationship between its luminosity and pulsation period. This relationship allows astronomers to use Cepheid Variables as standard candles to measure distances to other galaxies. In space and astronautical engineering, Cepheid Variables are important for determining the scale of the universe and for calibrating the brightness of other astronomical objects. They are also used in the study of stellar evolution and the formation of galaxies.
