SAT Writing Passage Title: Classifying the Stars

In astronomy, stellar classification is governed by the Morgan-Keenen system, which categorizes stars based on their composition and surface temperature. The origins of this system can be traced back to the work of Annie Jump Cannon, a late nineteenth century and early twentieth-century   1  astronomer. Spending over forty years classifying stars based on their unique spectra of transmitted light. [1]

Beginning early in her life, Cannon demonstrated an exceptional aptitude for the physical sciences. [2] Later, as a student at Wellesley College, Cannon earned a degree in physics and became an expert in spectroscopy: the process by which light is separated into its component wavelengths. [3] During this period, she also took up photography and traveled extensively in order to experiment with the newly invented black-box camera. [4] As a child, she developed an interest in astronomy and purportedly used her attic as a makeshift observatory.  2  

Cannon’s background in physics, astronomy, and photography provided her with a unique skillset that  3  will serve  ae her well for the rest of her career. After working as a research assistant for a number of astronomers at Wellesley and Radcliffe Colleges, Cannon was hired by Professor Edward Charles Pickering, the director of the Harvard College Observatory. Under Pickering, she classified over 300,000 stars-more than any other human in history-using only a telescope, a spectrometer, and a camera. Using this knowledge, she developed her own classification system that relied on the surface temperature of the stars, which could be approximated using the spectrum of light transmitted from each star. It was said that Cannon could classify three stars a minute and, using a magnifying glass, could classify stars down to the 9th magnitude-sixteen times fainter than  4  humans.

Today, Cannon’s unique classification system is used by countless astronomy enthusiasts around the world.    5  Pickering was succeeded by Harlow Shapley. Shapley once said that Cannon’s contribution to astronomy was “a structure that probably will never be duplicated in kind or extent by a single individual.”  Indeed, Cannon’s work has forever shaped our comprehension and perception of the vast and elaborate universe.
