I bet you’ve heard of Galileo & Hubble, but what about Henrietta Swan Leavitt?

Leavitt changed astronomy. She figured out new ways to measure a star’s distance from Earth & her work helped determine the universe is expanding.

Her boss, Edward Pickering, published her findings UNDER HIS NAME. Later, Shapley used her findings to determine distances around the Milky Way w/o credit.

Leavitt’s work is still used today. Next time you hear about famous men in #science share her story. #HistoryRemix
