Performances at 6 & 7:30 PM. The universe is both the setting and the story in Silent Sky by Lauren Gunderson, a play based on the life of astronomer Henrietta Swan Leavitt and her work with a dedicated group of women, including Annie Cannon and Williamina Fleming, at Harvard Observatory in the 19th century. It is a tale of passion, tenacity, sacrifice, luminosity, and working to find our place in the vastness of space.
