Great Minds of Astronomy: Cecilia Payne-Gaposchkin

The video explores the groundbreaking work of Cecilia Payne, who challenged early 20th-century beliefs about the composition of stars. Initially, it was thought that stars shared Earth's elemental makeup. Payne's research, however, revealed that stars are primarily composed of hydrogen and helium. Despite facing gender-based challenges, Payne's work laid the foundation for modern astrophysics, allowing scientists to understand star compositions and the universe's evolution. Her findings were initially dismissed but later recognized, leading to her becoming a prominent figure in astronomy.
