S. Shoemaker and D. H. Levy at Palomar. George Coyne (b. 1933), S.J., has been an astronomer at the Vatican Observatory since 1969 and its director since 1978. He has helped with the completion of the large Vatican telescope on Mt. Graham, Arizona. His polarimetric studies have centered on cataclysmic variables, among other subjects.
