In the mid-nineteenth century, Harvard Observatory began hiring women as calculators to interpret the results of nightly astronomical observations made by men. At first they were the wives, sisters, and daughters of the observatory's staff astronomers, and later they were joined by graduates of women's colleges. When photography became part of astronomical practice, the women, in addition to computing, began to study the stars captured at night on glass photographic plates. "The "glass universe" of half a million photographic plates accumulated at Harvard over the decades enabled women to make remarkable discoveries that were globally recognized. They helped to understand what stars are made of, to classify them and to find a way to determine interstellar distances. The book contains a wealth of interesting facts, with many excerpts from letters, diaries and memoirs. In fact, it is the story of the women whose contributions to science changed the way we think about the stars and humanity's place in the universe.
