This biography illustrates the accomplishments of a woman who developed a system of classifying stars and who-to this day-holds the record for identifying more stars than anyone else in the world. In 1925, Annie Jump Cannon became the first woman to be honored by Oxford University with a doctor of science degree. In addition to noting the achievements of the astronomer and her contributions to science, the book details Cannon's work and system of ranking stars by heat.
