When Cecilia Payne wrote her Ph.D. thesis in 1925, she quietly cracked open the sky.
Using spectral data, she made a shocking discovery: the Sun—along with most stars—is made almost entirely of hydrogen, the lightest element in the universe. This flew in the face of what every expert believed at the time.
A senior astronomer, Henry Norris Russell, told her not to publish. Four years later, he confirmed her findings—and got most of the credit.
Cecilia had already overcome the odds just to get that far. Cambridge wouldn’t award her a degree because she was a woman, so she left England and came to Harvard. There, she earned the first Ph.D. in astronomy from Radcliffe, a degree later called the most brilliant thesis in astronomy ever written.
Her work became the foundation for nearly everything we know about stellar composition and variable stars. She was eventually named Harvard’s first woman professor promoted from within—and later, first woman to chair a department.
But when she died in 1979, most newspapers barely mentioned her greatest discovery. No memorial. No textbook chapter.
Just hydrogen. Everywhere.
Cecilia Payne helped us understand the stars.
Now it’s time we remember hers.
