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.
