Quizplus · Accepted Answer

Edwin Hubble is renowned for measuring the distance to the Andromeda "nebula," classifying galaxies by their shapes, establishing the universe's expansion, and discovering the law that describes the motion of galaxies moving away from us. However, the discovery of the relationship between the period and luminosity of a Cepheid variable, which is crucial for measuring cosmic distances, was made by Henrietta Swan Leavitt.
