When Henrietta Leavitt begins work at the Harvard Observatory in the early 1900s, she isn’t allowed to touch a telescope or express an original idea. As Henrietta attempts to measure the light and distance of stars, she must also take measure of her life on Earth, trying to balance her dedication to science with family obligations and the possibility of love. Directed by Katie Hahn. Appropriate for all audiences.
