Henrietta Swan Leavitt's Astronomical Distance Method Recognized

Henrietta Swan Leavitt developed a key method for measuring astronomical distances while working at the Harvard College Observatory in Cambridge, United States. According to Space Daily, her work on Cepheid variable stars established the period-luminosity relation, which became a cornerstone for determining cosmic distances. This discovery has remained vital to modern cosmology, providing astronomers with a reliable tool to gauge the scale of the universe.
