NHAS - Today in Astronomy History

	1850	Italian astronomer Annibale de Gasparis, director of the Capo di Monte observatory in Naples, discoveres asteroid 13 Egeria.
	1885	American astronomer Harlow Shapley born. As a research student, Shapley worked under Henry Norris Russell at Princeton on the study of eclipsing binary stars. He later studied the distribution of globular star clusters and armed with that data determined the size and shape of our galaxy, and the direction to its center. He also discovered the Sculptor and Fornax dwarf galaxies.
	1889	American astronomer Edward Emerson Barnard observes an eclipse of Saturn's moon Iapetus by Saturn's ring system. Variations in Iapetus' brightness as it passed through the shadow of the rings led to the conclusion that the B-ring is opaque, but the C-ring is partially transparent.
