Before they even had the right to vote, a 
    group of remarkable women were employed 
    by Harvard College Observatory as ‘human 
    computers’. In the glass photographic 
    plates made by their male counterparts, 
    the women made extraordinary discoveries 
    about the night sky: they discerned what 
    stars were made of and measured distances 
    across space using starlight. 
                
  
    The author of Longitude, Galileo’s Daughter 
    and The Planets illuminates the hidden 
    history of these incredible women
    who changed the burgeoning field of 
    astronomy, our understanding of the 
    stars and our place in the universe.
