Edward Emerson Barnard,US astronomer
Edward Emerson Barnard (1857-1923),American astronomer. Having fostered interests in photography and astronomy from an early age,Barnard went on to become a pioneer in astrophotography. His technique allowed him to describe and catalogue a series of dark nebula. He acquired a reputation for astronomical observation,discovering numerous comets and Amalthea,the fifth moon of Jupiter. He deduced that novas were stellar explosions after noticing their gaseous emissions. The faint Barnard's star is named after him,as his observations led him to notice its unusually large proper motion,or speed across the sky,a sign that the star is close to the solar system
