The true story of Henrietta Swan Leavitt, one of the historic “computer ladies” at Harvard’s observatory in the early 20th century. Despite never being allowed to use the telescope, Henrietta made ground-breaking discoveries that shook the foundations of astronomy and made possible the work of Dr. Edwin Hubble and every astronomer to follow. Alternately poignant and funny, Silent Sky is a sweet, surprising look at
 one of the long-forgotten women of history.
