"Every evening, from the time she was a child, Maria Mitchell stood on her rooftop with her telescope and swept the sky. And then one night she saw something unusual--a comet no one had ever seen before! Miss Mitchell's extraordinary discovery made her famous the world over and paved the way for her to become America's first professional female astronomer."-- Provided by publisher.
