Barnard, Edward Emerson (1857-1923), an American astronomer, became famous for his skill as an observer. He studied at Vanderbilt University. In 1887, he joined the staff of the Lick Observatory at the University of California. There, he discovered the fifth satellite of Jupiter in 1892, and began a series of Milky Way and comet photographs. In 1895, Barnard joined the staff of the Yerkes Observatory in Wisconsin. His observations there led him to conclude that many starless spaces in the Milky Way are dark nebulae, consisting of clouds of dustlike particles. Barnard was born on Dec. 16, 1857, in Nashville, Tennessee. He died on Feb. 6, 1923.
