Happy birthday to #astrophysicist Cecilia Payne-Gaposchkin (1900-1979), trailblazer for women in #astronomy who discovered that hydrogen and helium are the most common elements in the universe.
Born England, she won a scholarship to Newnham College Cambridge in 1919 where she heard a lecture which changed her life. She wrote, “My world had been so shaken that I experienced something very like a nervous breakdown.” 🧵
