Caption: Michael Mumma. Portrait of Dr Michael Mumma, astrophysicist, on a background of a comet on a starfield. Dr Mumma works at NASA's Goddard Space Flight Centre on extraterrestrial physics, and studies the nature and composition of comets. Comets are lumps of rock and ice believed to be remnants from the formation of the Solar system. Dr Mumma and others believe that comets can reveal clues about the birth of this and other planetary systems, and even the origins of life. Only a fraction of the comets in the Solar system come close enough to the Sun and Earth to allow detailed study. Photographed in 1997.
