Join us for this presentation in honor of Women's History Month! In the late 19th and early 20th centuries\, women a stronomers of Harvard College Observatory calculated the distances\, tempe ratures\, and composition of the stars. They faced many challenges includi ng sexism from their male colleagues whose common belief was that women we re not worthy of earning college degrees and could never achieve serious s cientific accomplishments. Henrietta Swan Leavitt \;led the shift in a stronomical understanding of the scale and understanding of the universe. Annie Jump Cannon \;was instrumental in the development of the first s erious attempt to organize and classify stars based on their temperatures and spectral types. Cecilia Payne discovered that the stars were primarily composed of hydrogen and helium. Everyone has heard of Galileo and Newton \, now it&rsquo\;s time to learn about The Women Who Measured the Stars!&n bsp\;
