Description:
(American Astronomer and Astrophysicist) Cecilia Payne-Gaposchkin, an astronomer and astrophysicist, is renowned for her pioneering research on the composition of stars. In her 1925 doctoral thesis, she suggested that stars were chiefly composed of hydrogen and helium, a concept initially met with skepticism by the scientific community. Subsequent independent observations validated her conclusions. Her investigations into variable stars made substantial contributions to modern astrophysics, solidifying her status as a trailblazer in the exploration of the cosmos.
