Cecilia Payne's Revolutionary Discoveries
Cecilia Payne made groundbreaking discoveries about the composition of stars, determining they are primarily made up of hydrogen and helium. Her findings challenged the existing belief that stars contained similar elements in proportions to that of Earth. This insight was achieved through her detailed analysis of stellar spectra, previously organized by other astronomers into classifications, without a deeper understanding of their significance. By demonstrating that these elements were vastly more abundant than previously thought, she revolutionized the field of astrophysics.
