Born in Estonia, Öpik studied and began research at Moscow University. During World War I he helped establish Turkestan University in Tashkent. In 1921 he returned to Estonia to complete his doctorate and direct astronomy at the University of Tartu. He remained there, aside from four years at Harvard College Observatory, until forced to flee the Red Army by horse cart during World War II. His last four decades of active research were at Armagh Observatory, Northern Ireland, where he edited the Irish Astronomical Journal from 1950 to 1981. During part of this period he also held an appointment at the University of Maryland. Öpik established the foundation of the physical theory of meteors, developed new statistical methods and performed statistical studies of meteors, comets, and asteroids, and predicted the martian craters and the nature of the surface of Venus. He also made early contributions to stellar structure and evolution theory, showing the significance of nonuniform chemical composition in stellar interiors, and explaining the structure of giant stars. Öpik demonstrated that the spiral nebulae were extragalactic as early as 1922. Several of his contributions were not accepted until rediscovered by others much later. Although primarily a theorist, he invented a rocking camera for observations of meteors.
