galaxy (gāl'ək-sē) Pronunciation Key

Any of numerous large-scale collections of stars, gas, and dust that make up the visible universe. Galaxies are held together by the gravitational attraction of the material contained within them, and most are organized around a galactic nucleus into elliptical or spiral shapes, with a small percentage of galaxies classed as irregular in shape. A galaxy may range in diameter from some hundreds of light-years for the smallest dwarfs to hundreds of thousands of light-years for the largest ellipticals, and may contain from a few million to several trillion stars. Many galaxies are grouped into clusters, with the clusters themselves often grouped into larger superclusters.

"I never saw that great woman, Mary Wollstonecraft, but I have read her eloquent and unanswerable arguments in behalf of the liberty of womankind. I have met and known most of the progressive women who came after her—Lucretia Mott, the Grimke sisters, Elizabeth Cady Stanton, Lucy Stone—a long galaxy of great women.... Those older women have gone on, and most of those who worked with me in the early years have gone. I am here for a little time only and then my place will be filled as theirs was filled. The fight must not cease; you must see that it does not stop."
